sculpt mode, while others can work without problems on really high poly meshes with similar hardware.\n\n - On my main computer, brush strokes with TBB disabled feel more responsive regardless the mesh vertex count. When TBB is enabled, strokes usually stop generating new samples in the middle of the stroke or take a fraction of a second to start. I know this is happening to some other users. \n\n - Simple operations that need to loop over all vertices on high poly meshes are extremely slow for no specific reason. (doing x = 1.0f - x on a 25M elements array often takes up to 5 seconds). When the operation is more complex (like updating the normals or updating the nodes on the GPU), this can take minutes to finish. \n\nWe are not getting the reports of people that may be affected by this issue because most of them assume that Blender sculpt mode performance is just bad by default, so I can't tell if this is a problem with a specific configuration of hardware/software or a general problem in how the scheduler works. It would be nice to have more data from this test (and sculpt mode performance in general) on different hardware/software configurations to have a better understanding of how we can improve it. \n\n**How to test:**\n\n - Apply this patch: [P1202](P1202.txt)\n - Add a cube, subdivide N number of times and apply\n - Enter Sculpt Mode\n - Run \"Invert Mask\" (press A + drag left)\n\n\n**My results**\n\nOperating system: Linux-5.4.2-1-MANJARO-x86_64-with-glibc2.29 64 Bits\nCPU: Intel i7 6700K @ 4.00GHz x 8\nRAM: 32GB\nGraphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.64\n\n\nSubdivide default cube N number of times:\n\n| N Subdivisions | Vertices | PBVH Nodes | TBB ON (seconds) | TBB OFF (seconds) | DIFF |\n|--------------|----------|------------|------------------|-------------------|---------|\n| 11 | 25165826 | 7596 | 2.474073 | 0.571511 | 432.90% |\n| 10 | 6291458 | 1920 | 0.307948 | 0.159395 | 193.20% |\n| 9 | 1572866 | 464 | 0.111459 | 0.096845 | 115.09% |\n| 8 | 393216 | 112 | 0.002289 | 0.007297 | 31.37% |\n\n\nSubdivide default cube 6 times, use multires to N level.\n\n| Level | Vertices | PBVH Nodes | TBB ON (seconds) | TBB OFF (seconds) | DIFF |\n|-------|----------|------------|------------------|-------------------|---------|\n| 6 | 26763264 | 3696 | 1.076635 | 0.322183 | 334.17% |\n| 5 | 7102464 | 912 | 0.074586 | 0.113303 | 65.83% |\n| 4 | 1990656 | 232 | 0.012938 | 0.048273 | 26.80% |\n| 3 | 614400 | 56 | 0.004059 | 0.012778 | 31.77% |\n\n\nAs you can see, a simple loop over all vertices in the mesh is way faster on my setup with TBB disabled.\n\nIf I change the ##LEAF_LIMIT## in ##pbvh.c## to 100000 (x10) in order to increase the amount of work each node has and reduce the number of total nodes: \n\n| N Subdivisions | Vertices | PBVH Nodes | TBB ON (seconds) | TBB OFF (seconds) | DIFF |\n|--------------|----------|------------|------------------|-------------------|--------|\n| 11 | 25165826 | 760 | 0.106868 | 0.210985 | 50.65% |\n| 10 | 6291458 | 184 | 0.029088 | 0.105376 | 27.60% |\n| 9 | 1572866 | 56 | 0.007168 | 0.029653 | 24.17% |\n| 8 | 393216 | 8 | 0.002261 | 0.006321 | 35.77% |\n\nIf we compare the two results with TBB on:\n\n| Vertices | 1000 LEAF_LIMIT (default) | 10000 LEAF_LIMIT (new) | Perf. gain |\n|----------|-----------------|------------------|------------|\n| 25165826 | 2.474073 | 0.106868 | 2315.07% |\n| 6291458 | 0.307948 | 0.029088 | 1058.68% |\n| 1572866 | 0.111459 | 0.007168 | 1554.95% |\n| 393216 | 0.002289 | 0.002261 | 101.24% |\n\nIt seems like if we avoid starting TBB with a large number of nodes the performance improvement is huge. Increasing the leaf limit makes these kinds of operations up to 23 times faster, but that would be like disabling multithreading for small brush strokes.\n\n- Is there a way to fix this in the scheduler?\n- Can we do something like sending small chunks of nodes to TBB instead of starting the loop with 7000 nodes at the same time?\n- Can we find a better optimal leaf limit to get a better workload per core suitable for modern processors by comparing the results on different hardware? Dyntopo leaf limit is in 100 elements, which I think it does not make much sense.

", "[WIP] Design: Painting Color Management\nThis design are based on the next principles:\n\n* When mixing colors, do it always in the linear scene reference space. For Blender that is linear REC709.\n* Include the color space when storing colors for color picker and don't convert it the color channels.\n\n**Issues**\n\nCurrent issues we try to solve:\n\n* #68242 (Color space seems wrong while painting in image editor.)\n* Color picker stores in sRGB or linear REC709. the storage is defined by the RNA (COLOR, COLOR_GAMMA). Since blender 2.80 the default color picker is set to HSV, what has some usability issues (HSV has multiple values that represents the same black in sRGB and linear REC709). User notice this when they set `Value` to 0, that the next time they open the color picker that the `HUE` and `Saturation` are also set to 0. \n\n**Scoping**\n\nThe solution is focused on Sculpt/Paint brushes, but will be reusable in other areas. The solution is designed on single colors. `ImBuf` should be used when working with buffers. Changes to `ImBuf` are not in scope.\n\n**Proposal**\n\nProposal is to implement a framework for color picking and mixing colors. To test the framework we include the first implementation in the Paint and Sculpt Brushes. The idea of this approach is to be more explicit when colors are being used.\n\n__DNA__\n\nIn `DNA_color_types.h` add a struct that can store a color and relevant information of the color.\n\n```\ntypedef struct Color_RUNTIME_Color {\n float color_straight_alpha[4];\n float color_premult_alpha[4];\n} Color_RUNTIME_Color;\n\ntypedef struct Color_RUNTIME {\n /* flag contains the validity of the other fields */\n int flag;\n Color_RUNTIME_Color linear_scene;\n Color_RUNTIME_Color display;\n\n ...\n\n} Color_RUNTIME;\n\ntypedef struct Color3 {\n float components[3];\n float alpha;\n ColorManagedColorspaceSettings color_space;\n Color_RUNTIME runtime;\n} Color3;\n```\n\n`Color3.alpha` is always stored as straight alpha.\nThe runtime caches common conversions of the color in different OpenColorIO roles and alpha association. The `Color3.runtime` field will be flagged to be invalid when the scene color management is changed or a different scene is loaded. The runtime is also updated when the color management roles in the scene are changed, a another scene is loaded.\n\nIn `DNA_brush_types.h` deprecate the `rgb` and `alpha` and add a new field `Color3 color;`.\n\n__BKE__\n\nAdd functions in `BKE_colortools.h` for getting the values for a color in a specific OCIO Role, invalidate all `runtime` fields in loaded data, invalidate one `runtime` field.\n\n__UI__\n\nUpdate the color picker template to support this data structure. This also means that we don't do the pixel read to find the selected color, but interpret the screen coordinate on the wheel to find our what color has been picked.\n\n__Painting/Brushes__\n\nWhen doing this change a lot of compile errors needs to be fixed. This gives us the opportunity to migrate them to the new implementation and make sure we tackle these cases. Textures still needs special attention.\n\n\n__OCIO__\n\nThe color configuration needs to be adjusted with color spaces for the color picker role.\n ", "The Hair Particles interprets the color from the newer vertex domain and float color types wrong\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15\n\nBroken: version: 3.3.0\n\nI am trying to modify hair color using color attribute (called as vertex color in previous versions).

This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. For instance really dense drawings with small lines with little to no curvature still tends to flicker a lot.\nAnother case is when the gpencil strokes intersects the scene geometry. This makes the line less thick to the post process which makes it too small.\n\n## Proposed solution:\nWe propose to implement a Temporal AntiAliasing solution. It is robust and will match Cycles & EEVEE's film filtering if using the same filtering function. This only adds one temporary buffer (low VRAM usage compared to rendering at higher resolution) and is completely self contained (works with transparency and don't interfere with other features).\n\nI propose to only implement this for final rendering since it might introduce flickering that might be annoying while drawing.\n\nHowever this wouldn't solve the issue of gpencil strokes intersecting geometry.\nFor this I propose to erode or reproject the render's depth to match the render sample of the new AA scheme. This should fix the second problem completely.\n\n## Technical details:\n- Implementation just need to be ported from Workbench which has a lighter form of TAA than EEVEE. Also [D10414](D10414) can be of great help to reduce render/convergence time.\n- Depth buffer modification can be implemented after new AA is in." ]

that there is an access violation when reading at position `0xFFFFFFFFFFFFFFFF`. `node->typeinfo` does exist (is not null), but `freefunc` (and actually most of the other attributes) point to `0xdddd...`. Because of that, I think that this bug might be caused by a similar issue as described in #72833.\n\nI'm not sure if a core dump helps you, it's quite large (1GB + another GB for the .pdb file) so if you need it I can look for a way to make it available to you. I'm not a C or C++ dev so I don't know what is helpful.\n\n**EDIT**: I think this crash is caused by opening files files with nodes that were registered while the file was originaly saved but not anymore.\n\nIt's a bit complicated because it doesn't happen all the time. The particular file(s) where I observed this issue use nodes from an addon (Armory3D) which supports per-project custom nodes which get registered via a `on_load_post()` handler (so there is a delay between opening the file and registering the nodes). I'm not entirely sure, but it seems like the crash occurs when the nodes are registered again. The crash even occurs when unregistering the nodes before saving the file.\n\nBecause of that complicated setup (addon required + project setup + custom node package) I will go without an example file. If you aren't able to find the cause without one, please tell me so that I can prepare a minimal project setup for you.\n\nThank you very much!\n\n*Original issue*: 1890", "CommandBuffer Failed: cycles metal integrator_ shade_volume --MacOS--\nOperating system: macOS-13.3.1-x86_64-i386-64bit 64 Bits\nGraphics card: Metal API AMD Radeon Pro 5700 XT 1.2\n\nBroken: version: 4.0.0 Alpha\n\nStarts rendering fine until the error.

[ "Cycles: Vertex Color shader node is not handled properly/ignored if no vertex color is specified (should use the 'active_render' then)\nOperating system: Windows\nGraphics card: AMD Radeon R9 200 series\n\nBroken: 2.81a\n\nThe Vertex Color shader node is either ignored or not handled properly by the Cycles renderer. It works correctly in Eevee, and most (perhaps all) of the viewport rendering modes. In Cycles, the output of the Vertex Color node is always black. In order to have Cycles process vertex colours, it is necessary to use the old-style approach of creating an Attribute node and assigning it to the \"Col\" (default) attribute, or whatever the vertex colour data is named, if it is not the default.\n\nThe Blender project at Blender_Debugging-Vertex_Colours-0001.7z (also attached to this ticket) contains a minimal reproduction of this issue. It contains two cubes which are identical except that one uses a material where the output colour is based on the Vertex Color node, and the other contains one which is based on the Attribute node set to \"Col\". It will appear to be correct in most (if not all) of the interactive views in Blender, as well as when rendered in Eevee. When rendered in Cycles, the cube on the left will appear 100% black. The Vertex Color output is also treated as zero in any more complex shading pipelines, when rendered in Cycles specifically.\n\n[Blender_Debugging-Vertex_Colours-0001.blend](Blender_Debugging-Vertex_Colours-0001.blend)\n\nSample rendering in Cycles: (also available at Cycles_Vertex_Colours-0001.png)\n\n" ]

The compositor issues are more tangable.", "Mistranslated Modifier Option on MacOS using Logitech Mouse\nOperating system: MacOS 12.6\nHardware: Mac Studio M1\nBlender Version: 3.3.0\n\nI use a Logitech M500s corded mouse (FW 53.00.0011) and I programmed the 4th and 5th buttons (on the side) using Logi Options (version 9.70.29) to Modifiers, Shift on one, and either Ctrl or Cmd (I have not settled on which is better) on the other. This has worked fine on all my software until Blender.\n\nAlso, since the Middle button on the mouse is critical in Blender, and since the M500s defaults to side scrolling (which I never use) when you tilt the wheel and these activate way too easily, I re-programmed both the tilts to emulate a Middle mouse button click. I left the normal wheel scrolling untouched. This allows me to click or tilt the wheel to get a Middle mouse click without worrying if I hit it correctly. This has worked great in Blender, both the normal scrolling and middle mouse clicks work as expected.\n\nWhat does not work in Blender is my using buttons 4 and 5 as modifiers when I combine them with other mouse actions. I was getting unexpected results, so I used Keymap to find out what was happening, and discovered the following:\n\nPressing button 4 (or 5) alone works: I see the appropriate \"Ctrl\" (or \"Shift\") appear but it does not map, of course, as I am only providing a modifier. I see the same effect on the status bar when I press the buttons in the editors. I see the guides correctly change for each modifier press.\n\nPressing button 4 (or 5) with a keyboard key works: Blender correctly maps the appropriate modifier (Shift, etc.) with the selected key. Same happens in the editors, e.g. when I use the modified mouse button for \"Shift\" and hit \"A\" on the keyboard, the Add menu pops up correctly.\n\nPressing button 4 (or 5) with mouse Left or Right buttons fails: Blender maps the appropriate modifier (Shift, etc.) but with button 4 (or 5) instead of with the pressed Left or Right button. If Blender is doing this elsewhere, it would explain why I am not getting expected results in the Editors.\n\nPressing button 4 (or 5) with a Middle mouse button (any as programmed) fails: Blender maps the appropriate modifier (Shift, etc.) but with \"Wheel Up\" instead of with the Middle button. Again, this could explain my unexpected results in the Editors.\n\nBy the way, when I press button 4 (or 5) and move the wheel, I get the same map, the appropriate modifier with the appropriate \"Wheel\" direction, although I can get \"Wheel Down\" with the actual wheel.\n\nAlso, when I press a Middle mouse button alone (any three): Blender correctly maps the Middle mouse button as pressed. As it does with any other mouse action except the buttons modified to be Modifiers.\n\nI tested for this problem on my Windows 11 system. Different mouse, G502, and different options software (G Hub vice Logi Options) but same Modifier settings (Shift and Ctrl) for buttons 4 and 5.

When using touch, two fingers will scroll up and down. In Blender, two finger touch should work like an Apple touch pad or Apple magic mouse: two finger movement will orbit the view; holding down command zooms, holding down shift pans. Instead, it simply does nothing.\n\nBlender.app, default cube. Place two fingers down on a Wacom Intuos Pro tablet and move them around; it should orbit, but nothing happens. Well, the bottom status bar flickers back and forth as though command/shift or alt is pressed. \n\nThere are two reasons why this happens. \n1. Blender has incorrect Cocoa/AppKit code. I worked on AppKit for ~13 years at Apple. Below is a diff that addresses some of the issues. The code attempts to keep track of m_multiTouchScroll, but this isn't needed. It should key off of hasPreciseScrollingDeltas instead. I tested this diff with: Apple Magic Mouse, old school Apple scroll wheel mouse, Wacom tablet; all things work the same (except Wacom, which has the bug I'm reporting fixed). There is also a comment about intuos5, but that seems to be incorrect and outdated, but I don't have an Intuos 5 to test with.\n\n[0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch](0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch)\n\n2. Wacom's tablet touch drivers do link-checked behavior based on the bundle identifier \"org.blenderfoundation.blender\". In other words: they change the touch behavior when they see the target application is Blender. Wacom needs to fix this, but I'm not sure how to log a bug report for them.\n\nTo prove this, I created the sample application:\n\n[TabletTest.zip](TabletTest.zip)\n\nThe sample application has the blender bundle identifier set, as seen in this screen shot:\n\n\n\nIn ViewTest.m I log the flagsChanged:\n\n``` - (void)flagsChanged:(NSEvent *)event\n```\n{\n NSLog(@\"%@\", event);\n}\n```\n```\nIf you run the app and do a two finger scroll in the window you will see some flagsChanged logged, which is very strange because Shift/Alt/Cmd have not been pressed! Wacom is faking them for some reason, and changing the scrolling data, which messes up Blender.\n\nChange the applications's bundle identifier to \"org.blenderfoundationXX.blender\" (you can simply edit the info.plist) and run it again; it will then behave correctly.\n\n\n\nI don't know how to fix item 2 for Blender; I'm fixing it in my own build of Blender by changing the bundle identifier to org.blenderfoundation.bl3nder after it is built. I looked into identifying the events, and I can could identify the source as coming from the wacom driver but I can't fix them. \n\nI'm trying to find a contact at Wacom to have them fix this, but once it is fixed we still need item 1 fixed. \n\n\n\n", "Warnings, Restrictions, & Centralized Administration\nWith more organizations adopting Blender there is increasing need to simplify the deployment, maintenance, and administration of the program in large installations. This plan is meant to be a number of incremental steps that, once approved, I could implement myself. I have about 10 years of prior experience as a Domain Administrator on a network of approximately 600 users and 1000 computers in a Windows domain, and am familiar with the pitfalls and best practices.\n\n**Improved Warnings**\n\nThis doesn't seem related, but is. I would like us to implement something like [D10955: UI: Improved Operator Confirmations](D10955), which allow us to make warning dialogs much more easily than now that are also more informative, more customizable, and more differentiable. This way we can define many more than we have now to cover almost any situation where some users might want warnings, like when overwriting existing files or when files differ in version. We can define more because we'd also add the ability for users to easily enable/disable them.\n\n**Move Warning Configurations from Keymap to Settings**\n\nRight now the configuration of warnings is quite obscure, buried in the keymaps as an attribute of the entry. Most users will not be able to change the current warnings. I'd like to make a \"Warnings\" section in Settings with checkboxes to allow quick enabling and disabling of warnings.\n\n**Expose Factory Settings**\n\nRight now the default startup file and the factory preferences are only stored inside the executable. I'd like to optionally expose those for customization. Perhaps add a command-line argument to the executable that extracts copies of the embedded \"default.blend\" and \"prefs.blend\" to the install folder. These would be used instead, if present, in the same way that you can now override the splash image with a custom \"splash.png\".\n\nIn a large deployment you would put the blender installation folder in a shared read-only location that everyone would launch. That way you only have to install it once, not on every workstation. With this change you could, for example, change the fonts directory to be a shared network location. Change that in this one place and it becomes the default for everyone.\n\n**Add Restriction Settings**\n\nLike the \"Warnings\" section in Settings, I'd like to add \"Restrictions\". So checkboxes that, once enabled, restrict the user from doing some operations. For example to not allow the installation of addons. In a single-user installation this would not be used. But imagine an administrator setting these, along with warnings, and placing a \"prefs.blend\" file in the shared read-only network location of the Blender installation. It now means everyone on the network has the same defaults, warnings, and restrictions.\n\n**Project Settings**\n\nAs another layer of granularity, allow putting these shared defaults and preference files within the folder path of blend files. So while loading any \"blend\" file we also look in its folder and parent folders for defaults and prefs. This way you can have per-project settings.\n\n**Platform Enhancements**\n\nDuring startup we are loading settings for settings, warnings, and restrictions. Once this is done we could also call platform-specific routines if they exist, like checking settings in the Windows Registry for example. This is all that is required to support Group Policy, so an Administrator can set a path for all user, allow some groups to add addons, and only leaders to change restrictions, etc.\n\n" ]

However, there are many situations where it would be handy to be able to edit actions that can be reused on other levels instead (for example, actions for different sets of colour+intensity cycles for lamps - e.g. for a disco scene or something like that).\n\n**Problem**\n*1) How do we make it clear to users which level/slot they're editing?*\n- For example, with a single Cube selected, we could potentially have Scene, Compositing Nodes, World, Cube Object, Cube's Material 1, Material 1's Texture..., Material 2, ..., Cube Mesh, ShapeKeys, Particle System 1, Particle System 2,..., and perhaps a few others I've overlooked.\n\n*2) How do we allow users to select which level + slot they're editing?*\n- This naturally follows from the first problem. Basically, if we can display a slot, we can probably try to reuse that mechanism for primitive selection techniques.\n\n**Solutions**\n # **Level + Slot Selectors** - This would be similar to what the IPO Editor used to have (File:ManAnimationEditorsIpoWindowDefaultViz.png).\n - *Benefit:* This is a fairly self-contained approach, and one of the easier ones to implement.\n - *Problem 1:* This was quite nasty if you selected another object that didn't have the types of data that the previous one had. Then again, the Properties Editor suffers from similar problems too.\n - *Problem 2:* Also, it didn't really handle things like materials that well (these were accessed using a number box to choose the index being edited)\n # **Mini-Outliner of Available Slots** - This is a more advanced version of the Level + Slots idea, except that we display a mini tree of available levels that can be edited given the current selection, with the hierarchical relationships between datablocks visible\n - *Benefit:* This copes better with things like Materials and Particles\n - *Benefit:* This is still a \"self-contained\" approach (i.e. each editor doesn't need to know anything about other editors' states)\n - *Problem:* We'd have to develop a new widget to do this - somewhat hairy in the current UI widget toolkit, but we'd want to do this for RNA Path building anyway\n - *Problem:* We'd end up with a semi-blocking/overlapping view that users have to interact with everytime they hunt for this info.\n # **Defer to Outliner (Proper)** - Instead of creating our own outliner tree and using a localised pointer, we just defer these capabilities to the main Outliner. Thus, clicking on Action Slots there (or just the Animation Data entries) tells the Action Editor where it needs to be.\n - *Benefit:* Potentially simpler for users who just expect applications to be monolithic blobs where every single view cooperates with every other view to present a single editing state/context\n - *Problem:* What happens when we've got multiple of each type of window, and we want to have separate views in each?\n # **Controlled by DopeSheet** (From an old suggestion by @venomgfx) The Action Editor can only be entered via DopeSheet. Double-clicking on a channel there opens Action Editor for just that action+level (i.e. in effect it filters the visible channels to just those in that action). When selected object changes or we exit action editor (i.e. back to dopesheet), the slot/level pointer stuff gets reset and/or the Action Editor simply becomes unavailable.\n ", "Stronger binding of Active and Selected\n**Context**\n\nFor many things that can be *Selected*, there is also a state called *Active*. There can be 0..∞ *Selected* things, and 0..1 *Active* things. This applies to objects, bones, fcurves, fcurve keys, mesh elements, and more. These will just be referred to as *thing* in this task to avoid having to repeat that entire list.\n\nThe *Selected* and *Active* states are independent, so there are four states a thing can be in:\n\n| | Not Selected | Selected |\n| -- | -- | -- |\n| Not Active | x | x |\n| Active | x | x |\n\n**Problem**\n\nThere are two states possible that can cause issues:\n1. **There are *Selected* things, but none of them is *Active*:** a sidebar/numerical/properties panel will not show information, and generally be empty without explanation why.\n2. **There is an *Active* thing, but it is not *Selected*:** this is not shown in the UI, as there is no separate color for this situation; all *Active* things are shown the same way regardless of them being *Selected* or not. This causes confusion and unexpected behaviour, and also doesn't allow for an actual clear use of this possibility.\n\n**Related Reports**\n\nThese reports are examples of confusing situations where the disconnect between *Active* and *Selected*. The list is not exhaustive, and may be expanded later.\n\n- #14429 (selected bone is not active)\n- #65219 (Objects don't become active object if they are selected by a box)\n- #68647 (objects selected using box select cannot be moved to collection if there is no active object)\n- #81922 (The Graph Editor doesn't show any curve of the Armature (if in Pose mode, but armature unselected, with box/circle/lasso tools))\n\n**Proposal**\n\nThis design task proposes linking *Active* and *Selected* such that:\n1. If there are *Selected* things, there is always one of those that is the *Active* thing.\n2. If a thing is *Active*, it is also always *Selected*.\n\n**Hurdles to Overcome**\n\nRule 1. above requires that one of the selected things is marked active. There is not always a unique, obvious choice here, for example when box-selecting multiple things at the same time. In this case the choice should at least be consistent so that users know what to expect after a while. The thing closest to the mouse cursor (when using the mouse to select) could be a reasonable choice.\n\nRule 2. above can be dealt with in various ways:\n- Create a function that returns the *Active* thing, and make it return nil when that thing is not also *Selected*. This is what was implemented for the Active Keyframe (983ad4210b).

I'd like to share some of my observations and maybe discuss possible \nimprovements for consistency with you. \n \nOverview: \nBlend file: [booleans-bmesh-vs-carve.blend](booleans-bmesh-vs-carve.blend)\n(Note that you need an older Blender build with Carve) \n \nOur premise always was to make the Fracture Modifier a robust tool that should \nnot be nitpicky about the given input mesh. It should basically work for the \nartist at all times. This means the FM should also accept and work with \nnon-manifold, self-intersecting and complex meshes which are typical use cases \nin production and provide solutions for that. We have used Carve for this in \nthe past and analyzed and utilized its behavior to make that possible, thus my \ntests include all those possible variants. \n \nResults:\n\nMy first impression was that Bmesh is doing quite well now. It produces more \npredictable results for non-manifold targets and even for some manifold ones. \nHere are my observations: \n \n1 - Bmesh is leaving free edges in non-manifold results (well visible in orange \nin the lower right), those should be removed after operation. \n \n2 - Bmesh is not face normals aware. I'm not sure if this is good or bad thing \nin a higher sense, but I know that this is limiting factor for some users (see \ninverted normals variants which would flip results in Carve). \n\n3 - As a result of 2. Bmesh can produce meshes with inconsistent normals as it \nkeeps the original normals of the operator object but ignores them for the \nactual boolean operation (row 3 and 6). \n\nThis is what I could see, maybe there are more differences. I think that Bmesh \ncould be more consistent with Carve in general but it should at least output \nclean results.

Because of that, I think that this bug might be caused by a similar issue as described in #72833.\n\nI'm not sure if a core dump helps you, it's quite large (1GB + another GB for the .pdb file) so if you need it I can look for a way to make it available to you.

The particular file(s) where I observed this issue use nodes from an addon (Armory3D) which supports per-project custom nodes which get registered via a `on_load_post()` handler (so there is a delay between opening the file and registering the nodes). I'm not entirely sure, but it seems like the crash occurs when the nodes are registered again. The crash even occurs when unregistering the nodes before saving the file.\n\nBecause of that complicated setup (addon required + project setup + custom node package) I will go without an example file. If you aren't able to find the cause without one, please tell me so that I can prepare a minimal project setup for you.\n\nThank you very much!\n\n*Original issue*: 1890", "inset and bevel edits crashing blender 3.x\nThreadripper 1950x 128 gb ram 2tb SSD (home)\nNVIDA 3080 updated to latest drivers\n\nIntel i7 64 gb ram 2 tb SSD (work)\nAMD 6900xt updated to latest drivers\n\n\nHappens on all 3.x versions of blender.\n\nIssue happens on both my home PC (the thread ripper) and my work PC.\n\nStart editing default cube add bevels, insets place some cuts... crashes within a couple of minutes.

I'd like to share some of my observations and maybe discuss possible \nimprovements for consistency with you. \n \nOverview: \nBlend file: [booleans-bmesh-vs-carve.blend](booleans-bmesh-vs-carve.blend)\n(Note that you need an older Blender build with Carve) \n \nOur premise always was to make the Fracture Modifier a robust tool that should \nnot be nitpicky about the given input mesh. It should basically work for the \nartist at all times. This means the FM should also accept and work with \nnon-manifold, self-intersecting and complex meshes which are typical use cases \nin production and provide solutions for that. We have used Carve for this in \nthe past and analyzed and utilized its behavior to make that possible, thus my \ntests include all those possible variants. \n \nResults:\n\nMy first impression was that Bmesh is doing quite well now. It produces more \npredictable results for non-manifold targets and even for some manifold ones. \nHere are my observations: \n \n1 - Bmesh is leaving free edges in non-manifold results (well visible in orange \nin the lower right), those should be removed after operation. \n \n2 - Bmesh is not face normals aware. I'm not sure if this is good or bad thing \nin a higher sense, but I know that this is limiting factor for some users (see \ninverted normals variants which would flip results in Carve). \n\n3 - As a result of 2. Bmesh can produce meshes with inconsistent normals as it \nkeeps the original normals of the operator object but ignores them for the \nactual boolean operation (row 3 and 6). \n\nThis is what I could see, maybe there are more differences. I think that Bmesh \ncould be more consistent with Carve in general but it should at least output \nclean results. We have no \"make normals consistent\" modifier in Blender for \ninstance to fix normals within a modifier stack. \n \nI'm aware that these are not necessarily considered being bugs, so I'm just \nputting it here for discussion and making you aware of that.\n", "particle system collisions stop working outside 255 blender units\nOperating system: windows 10\nGraphics card: gtx 1080\n\nBroken: 2.79b 2018-3-22, \nparticle systems do not interact with faces which are oriented in the axis where the face is more than 255 blender units away from the origin\n[name ]([particleproblem.blend](particleproblem.blend))", "Vertex Paint Viewport Overlays stencil mask not working\nplatform: Windows-10-10.0.19042-SP0\nGraphics card: 1080\n\nBroken: 3.1.0 Alpha \n```\n commit date: 2021-11-14 00:26 hash: 7e82c840b7a4\n build date: 2021-11-15, 00:51:48\n```\n\nWorked: Has'nt worked for ages\n\nGo to vertex paint mode, select some polys on a model.\nGo to overlay options/vertexpaint/stencil mask opacity the slider does nothing to unselected polys overlay.\n\n\n\n\n", "Regression: Surface Deform modifier bind to object with different viewport/render subdiv level will be buggy when rendering\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.49\n\nBroken: version: 3.3.0 Alpha\nWorked: version: 3.2.0\n\nIf object A has a subdiv modifier with different level for viewport/render, and object B has a SurfaceDeform modifier that bind to A.\n\nWhen A is deforming in viewport, B will also deform normally in viewport. However in rendered result, B will become chaotic. Clearly the 'bind' option in B's SurfaceDeform modifier remembers A's vertices that subdived for levels of viewport setting, but when rendering, A will be subdived for levels of render setting, and have a different number of vertices, making B's bind invalid.\n\nAny other modifiers with bind option, e.g. MeshDeform, may also suffer from this.\n\nI wonder if this can be fixed. Two possible solutions:\n1. for every subdiv step, add additional vertices at the end of original vertices. So the original vertices will remain index unchanged, and the bind may work as well.\n2. When rendering, check if render subdiv level != viewport subdiv level, and always use viewport subdiv level for binding of any other modifiers.

Fixing both of these doesn't correct any of the above issues -- although it IS normally advised since it prevents a few shading and modelling issues -- but it does, for some reason, change how the errors manifest, like the model collapsing in a slightly different way or the CTRL-R shortcut suddenly causing the same issues the tool version of loop cut and slide has.\n\nConclusion: you've somehow managed to turn this mesh into some form of invalid geometry that Blender can't seem to handle properly.

Right now, I'm trying to decimate a simple model with about 45k vertices only. The decimate modifier is working fine on default settings i.e., on 'Collapse' setting .. but as soon as I switch to 'Planer' .. Blender becomes unresponsive for several minutes at least (and also indefinitely in some cases). \n\nI noticed that in my task manager, the Blender is only using 29% of CPU.. and regarding RAM .. on one side it shows 61% usage, while the actual usage is only 289MB in the value column (see screenshot).

For example, if the frame I wanted to render was 187, I would render frame 187.1 or 187.2 until blender would render the frame.\n\nI believe the problem relates to a model I had commissioned, but I cannot recreate the issue in other blend files with that model.\n\nGPU memory usage is about 7.6/8 Gb, so there is headroom, and there is plenty of RAM. It does not matter if it is rendered on GPU/CPU, GPU only or CPU only it will always crash.\n\nI have tested on 2 other Windows computers with the same results, so it is not Ubuntu related.\n\nOther frames render perfectly.\n\nThere is no issue with viewport render mode. Often I get \"out of memory\", but that is only because Blender does not dump some things from memory before viewport rendering an updated scene. It's bound to be a known issue and easy to work around.\n\nI have prepared the file to upload here, but it's 1.9 Gb zipped.

I have spent 3 solid weeks trying to troubleshoot this and the only reliable way I know of reproducing the issue is with the full file.\n\nN.B. The update to 3.6.1 saw me return to this with an updated and improved version of the file. Background rendering will SOMETIMES render problem frames.

[ "Subdivision modifier does not interpolate zero weights.\nOperating system: Linux\nGraphics card: Intel UHD\n\nBroken: 2.90.1\nWorked: ???\n\n\nThe subdivision modifier usually interpolates both value and membership across subdivided vertices.\n\nThis allows it to be used in non-destructive, modifier-based workflows that operate on or using vertex groups.\n\nIt does not do this, however, when vertex weights are equal to zero. The original vertices retain their (zero-weighted) vertex group membership, while new vertices in between them have no vertex group membership.\n\nAn example of why this is problematic is screenshotted below, with the file attached:\n\n\n\nEach Subdivision'd sphere has a bumpy texture applied using a Displace modifier after a textured VertexWeightMix modifier.\n\nThe rightmost sphere has its vertices weighted to 0.01, and interpolates and behaves correctly.\n\nThe leftmost sphere has its vertices weighted to 0.00. It intuitively (and, numerically/extrapolatively) should be indistinguishable to the 0.01 sphere. Because its weights aren't correctly interpolated, it instead ends up with a bunch of spikes at each of its original vertices.\n\nThe middle sphere has vertices weighted in a gradient from 0.00 to 0.50. It serves as an example of a feasible real-world application which would be broken by this kind of behaviour. Perhaps the original vertex weights act as a sort of base heightmap for a terrain model, and the changes made by the Subdivision and textured VertexWeightMix modifiers add an extra layer of detail. In this case, the clear and useful behaviour would be for behaviour to be continuous in the transition from 0.01 to 0.00. Instead, there is a sharp cutoff at 0.00, and inconsistent and discontinuous behaviour after that.\n[ZeroWeightSubdiv.blend](ZeroWeightSubdiv.blend)\n\nApply a subdivision modifier to a mesh with zero vertex weights, then check the vertex group membership of its vertices afterwards.\n\nOr download and open the attached `.blend` file.", "Bevel modifier/tool expands vertex groups into surrounding geometry\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3060 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 497.09\n\nBroken: version: 3.1.0 Alpha\n\nWhen beveling geometry with avertex group assigned, some of the surrounding vertices are added to that group after beveling.

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "GN: Delete Geometry node hides edges in some cases\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.23\n\nBroken: version: 3.2.0 Alpha\n\nHard to describe this one more abstract..\n\nI start with a mesh line primitive (0,0,0) (0,1,0) and extrude it **n** times along **x** to get a grid.\nNow I try to delete all points with a distance from the **y** axis greater than **d** \nWhenever **d** lies between the first and the last extrusion, the edges of the starting primitive are not displayed.\nIt shows up in the spreadsheet however and reappears if I apply the modifier and tab into edit mode and back \n\n[2022-02-05 19-27-50.mp4](2022-02-05_19-27-50.mp4)\n[del_geo_node.blend](del_geo_node.blend)\n\n", "Working on a mesh that has a high multires subdivision causes blender to build Up memory even on lower levels.\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.99\nRAM: 16GB\nCPU: AMD Ryzen 7 3800\n\nBroken: version: 3.6.0\n\nWhen editing a mesh that has been subdivided a few times will cause blender to increasingly start to consume more and more memory aggressively even if the modifier is turned off.\n\nSubdivide the mesh a few times using the multiresolution modifier, noted on 5-up levels on a mesh with originally 9 272 faces. then either switch the modifier Viewport Level to either 1 or disable It entirelly, start editing the mesh in edit mode the memory consumption stats will start to skyrocket with no signs of going back down until blender starts slowing down the computer and/or crashes entirely.

Create a scene in Cycles.\n2. Change to the rendered viewport.\n3. Open a shader editor and change to the `World` shader and delete the `Background` node.\n4. In the `World Shader`add a `Magic Texture` node and connect one of the outputs to the `Volume` socket on the `World Output` node.\n5. You will noticed that in the viewport you can see the `Magic Texture` is projecting light onto objects in the scene, but you can't see the `Magic Texture` directly.\n6.

Place a `Volume Scatter` node in the `World Shader`, connecting the output to the `Volume` socket on the `World Output` node and connect the output of the `Color Ramp` node to the `Density` input of the `Volume Scatter` node. You can now see the noise texture in the volume if you have a light in your scene.\n8. Select the left most handle (the handle that is black) in the `Color Ramp` node and drag it closer to the position `0.5`. You will see the results you expect until you reach the position `0.5` where the volume will seem to disappear from your scene.

It seems that Cycles is only partially recognising changes made to the scene in the pre_render, pre_frame, and post_frame handlers. \n\nIn the below zip file there are 3 directories, each containing a blend file with a simple script to demonstrate the issue. The script changes the file output node's base path, and it also changes blender own render.filepath in the output properties panel. The new file name includes the scene camera name (which changes on frame 1 and 3 using markers) and the frame number when the handler updated the filepath/base_path properties, followed by the __0001 added by Blender. For example frame one should read: left cam_updated_path_on_frame_1__0001.png\n\n**Steps to reproduce problem**\n\n\n\n - Unzip [cycles handler bug.zip](cycles_handler_bug.zip)\n - open each of the blend files in place (use 'load UI' as I've set up the workspace for the easiest testing)\n - notice that the blender output is set to 'not set yet', as is the file output node in the compositor.\n - choose to render the animation\n # In the folder where the current blend file resides there will now be two additional folders, one for blender's output, and another for the file output node's results.\n\n\n**Results**\n\n**pre_render handler**\n\nAs expected the camera is incorrect because the pre_render handler happens before the scene has been evaluated. Although strangely some of the information is for the unevaluated frame that the playhead has just moved to (the frame number) and some is for the frame the playhead was on prior to beginning rendering (the camera name which was active on frame 4 before the playhead moved to the beginning of the animation ready for rendering in this example).\n\nBlender's own image sequence output does use the new path which was assigned whilst in the first frames pre_render handler, but on the first frame, the camera name is incorrect and the frame number is correct:\n\n\nThe file output node images however show that cycles didn't recognise that the base_path property had been updated until the next frame. We can see here that the file ending in __002.exr was updated on frame 1, but not used until frame 2, and this continues all the way through.\n\n\n\n**pre_frame handler**\n\nStrangely, although this handler also fires prior to the scene being evaluated (directly after the pre_render handler), this time Blender's own output shows the camera name is now correct, but again, the updated file output node is still not being used until the following frame:\n\nblenders output:\n\n\nfile output node's output:\n\n\n\n**post_frame handler**\n \nBlender's output again is correct, but the file output node's new path is not being recognised:\n\nBlender's output:\n\nFile output node's output:\n\n\n\nThe above can be worked around with code by grabbing the camera from the marker list instead of the active scene camera, but one really major issue for us is that even when locking the viewport prior to rendering, if we update the file output node's base_path, we start experiencing occasional Access Violations and instant crashes, this happens even if the file output node's path is not visible to UI. (perhaps this is related to the reason why the base path isn't being recognised until the next frame?)\n\n\n", "Auto perspective sometimes fails\n**System Information** \nOperating system: Windows 10\nGraphics card: 3070\n\nBroken: 3.2.0 and 3.2.1\nWorked: 3.1\n\nAuto perspective setting doesn't work in this case: if you are in camera view or any side view and then you are switching to another side view you have this smooth transition animation between views.

These are still modifiers and show up in the list as such, but they show a \"_Settings are inside the -context- tab_\". Not ideal.\n\n\n\nIn recent years, users have gained the ability to build their own modifiers using Geometry Nodes. This has led to incredibly complex modifiers featuring long lists of settings.\n\nThere has to be an easy way to list, and tweak modifiers.\n\n## The Solution\n\nLists.\n\nThis is not a new idea. Lists have been proposed several times with the oldest record I could find dating back to [this PDF from 2014 by Cole Reed](Modifier_Proposal.pdf). As well as [design tasks](38178), [RightClickSelect proposals](?sorting=hot), [community hacks](1106948247489257475), and [add-ons](1147752).\n\nThis was proposed over the years again, with the most recent being for Blender 3.0. The main reason against turning the modifier stack into a `UIList` widget is the loss of the [nice drag & drop](9b099c86123fc828a194c59ce5b8bbf5a56f9cdb) that was added back in 2020. With the new **List** widget this will no longer be an issue.\n\n## The List\n\nA list will contain all modifiers for the active object.\n\nAdding and removing modifiers will be done via the familiar `+` and `-` icons, same as in every other List in Blender.\n\nVisibility settings for each modifier will be icons on the right side. Dropdown items to `Apply`, `Apply as Shape Key`, and so on, will be in the dropdown button (under `+`/`-`). This dropdown could contain new operators that apply to the entire stack. Like `Apply All Modifiers`, `Delete All Modifiers` (some operations part of the popular **Modifier Tools** built-in add-on).\n\nModifier settings will still be inside a panel as it is currently, but the panel's header will be much simpler since visibility toggles are in the list now.\n\n\n\nThe `Particles` tab goes away. Particles Systems show up in the list of modifiers. When a Particle System is active, their settings will show up in a panel. All panels currently containing particle settings will be sub-panels.\n\nMost of the physics systems will show up in the modifiers list as well. With the exception of those that are not part of the modifier stack (**Force Fields** and **Rigid Body**). Each physics system will be a panel (just as it is currently).\n\n### Multiple Items\n\n_Optional. Just food for thought._\n\nOne modifier must be active, but several could be selected and displayed at the same time, to easily compare values or apply settings to multiple at once.\n\n\n\n## The Add Menu\n\nImplemented in !111717\n\n----\n\n\n\n\nThe current menu has issues:\n* Can't be searched\n* Too many items for accelerator keys to be useful (Mirror is one of the most popular modifiers yet it's not underlined)\n* Won't fit in small windows (an issue on all big dropdowns)\n* Categories are vague (is the Ocean modifier considered physics?, Mask modifier doesn't \"Generate\", it removes geometry)\n\nBut the main issue is that it can't be extended. Users could make their own modifiers and have them show up in the Add menu.\n\nSimilar to the `Add Object` or `Add Node` menus, a new list-style `Add Modifier` menu will look more familiar and be easier to navigate. With the upcoming [search in menus](110855) feature allowing to quickly find what we're looking for.\n\n\n(mockup using the current categories as example, this should be re-organized once the new system is in place)\n\nAt the bottom of the menu there will be our custom-made modifiers, grouped by catalogs, similar to how Node Group assets show up in the `Add Node` menu in Geometry Nodes.\n\nTo make adding modifiers faster, users can press `Shift+A` with the mouse over the properties editor to spawn the `Add Modifier` menu.\n\n## Conclusion\n\nAgain, this is not a new idea, but I believe Blender now has many of the pieces required to make this finally happen (the new Lists view, node/modifier panels, modifier assets).\n\nThis will make it easier to replace (and improve) the current modifiers with the help of the community, and make custom-made ones integrate seamlessly.\n\n## Plan of Action\n\nThis project will need a team. Some of the work can be done simultaneously by two devs, such as the `Add` menus is a separate project from the List display.

The duplication automatically selects the new object in the 3D viewport but this selection differs from that shown in the outliner. This means dragging to, say, a new collection does not work as expected (only the parent object is moved leaving the child behind).\n\nThe set up (this is the attached blend file):-\n1. Create two cubes (or any meshes) and parent one to the other to form a hierarchy.\n2. Add the object(s) to a collection.\n3. Create another top level collection which is empty.\n\nThe aim:-\nTo duplicate the object(s) (not the collection) and copy the duplicate to the second (currently empty) collection.\n\nThe steps:-\n1. Right click the parent object in the outliner and choose \"Select Hierarchy\". Note that the outliner shows the selected objects with a blue background bar (as expected).\n\n2. In the 3D viewport, use Shift or Alt D (doesn't matter which) to create new duplicate objects. Note that the 3D viewport shows the duplicate parent and child selected. The outliner shows a new object selected (with blue bar) but the tree is collapsed so we can't see the child.\n\n3. In the outliner, click and drag the selected parent object to the empty collection. Note that only the parent moves, the child is left behind. This child has then to be dragged separately.\n\nAfter step 2, every visual cue leads the user to believe that the duplicate hierarchy is selected. And this is the intuitive behaviour expected. But expanding the outliner tree shows the child object is not, in fact, selected (no blue bar). So an additional step of having to reselect the hierarchy is required before step 3.\n\nThe main issue is that with lots of objects and detailed hierarchies, just forgetting that additional \"select hierarchy\" step before dragging means that child objects can be scattered all over the place away from their parent and the user is left picking through the large list trying to sort it out.\n\nThis may not be a bug, it may be working as designed.

It will be worked a bit more after discussion within the module, and presentation and diagrams will become more clear.\n\nThis document describes caching system which design and implementation for the `VSE 2.0 project` (#78986).\nThere is some intersection of performance topics listed in the `VSE 2.0: Performance ` (#78992). \n\n## User level design\n\nOn user level cache system should follow zero configuration principle: the video playback and tweaking should be as fast as possible without user spending time on fine-tuning per-project settings.\n\nThe only settings which user should be interacting with are in the `User Preferences`:\n* In-memory cache size limit\n* Disk cache size limit\n* Disk cache folder\n\nThese settings are set once in the User Preferences and are used by all sequencer projects. The default values are based on the minimal [[ requirements/ | hardware\nrequirements ]].\n\n## Code design\n\n### Levels of caching\n\nFor best editing and playback performance multiple levels of cache are needed.\nThe most important ones are:\n\n* Cache of strip input (colormanaged using general Blender color space rules)\n\n```\nThis allows to faster, without lag, move image strip in time, adjust strip settings like transform, by avoiding need to re-read file on every modification. Lets call this cache level `STRIP_INPUT`.\n```\n\n* Cache of the final sequencer result.\n\n```\nThis allows to have realtime playback after the sequencer got cached. Lets call this cache level `SEQUENCER_FINAL`.\n```\n\nThe simplified flow of the image from disk to the artist is presented in the following diagram:\n\n\n\n---\n**NOTE**\n\nNeed to think about whether having strip output cache is helpful. If the stack rendering is fast, having extra levels of cache will have negative affect due to less final frames fitting into the memory.\n\n---\n\n### Cache referencing\n\nCache levels are to utilize reference counting as much as possible. For example, when having single Image Strip without modifications set up in the strip the final sequencer frame in the `SEQUENCER_FINAL` cache is to reference the image from `STRIP_INPUT` cache. This allows to minimize memory footprint, playback performance for the story boarding type of tasks performed in the sequencer.\n\nThe following example visualizes cache frame referencing in the following scenario:\n\n* Sequencer have single Image Strip using `HappyFroggo.png` as an input. The strip has length of 4.\n\n\n\nIn Blender terms, the cache contains a single copy of `ImBuf` created for `HappyForggo.png`. All the sequencer cache entries are referencing this `ImBuf` for lowest possible memory footprint.\n\n### Cache resolution\n\nIn a typical video editing scenario an artist views the sequencer result in a rather small area of the screen layout:\n\n\n\nThis behavior can be exploited in the following way: the sequencer processing and caching can happen in the lower resolution. This is something what current proxies design is solving, but does in the fully manual manner.\n\nThere is a possibility to make proxies behavior more automatic, by performing downscale on an image after it was read from disk, but before it gets put to the `STRIP_INPUT` cache. Default behavior could be something like:\n\n* Use closest power-of-two downscaling (similar to mipmaps)\n* The target resolution is 50% of the window resolution, but no more than 1080p.\n\nIn order to support workflows where an artist needs to investigate in a close-up manner the final result, there will be a display option `Best Quality` (but defaulting to `Best Performance`). This could fit into existing `Proxy Display Size` menu.\n\nIn the future more automated input resolution selection is possible to be implemented. For example, it is possible to automatically switch to the\n`Best Quality` mode when zoom-in is detected.\n\nImage scaling with a power-of-two scale factor can be implemented very efficiently using threading and vectorization.\n\nOn a performance aspect, for image sequences such scale down will be an extra computation, which will only pay off if effects/transformation is used.\n\nFor the movie files, this step will actually make things faster because it is required to convert color spaces (happening in `sws_scale`), which is not\nthreadable. The scale down will be done together with color space conversion, which is expected to give better performance compared to the current state of the sequencer playback.\n\n---\n\n## Task progress\n\n- [x] Cache referencing\n - d837923a56\n - c74086376f\n\n- [x] User level design\n- [x] Levels of caching\n - f448ff2afe\n - 445ebcaa30\n\n- [ ] Cache resolution\n - [D9414: VSE: Render in size nearest to preview image](D9414)\n - Update/followup above patch to work on images" ]

[ "Update property when adding or removing keyframe\nRemoving keyframe can cause issues in all editors and adding keyframe needs to update VSE.\n\nWhen removing keyframe, RNA update function should be called, since property value may change. This is reproducible with simple 3 keyframe animation, place CFRA on middle keyframe, remove (press Shift + Alt +I on propery in side panel) it and no update will happen.\n\nWhen adding keyframe, sequencer prefetch is not notified about this change. So it works on outdated data until keyframe is added. Simply notifying prefetch is not enough and cache must be cleared too which is currently done from RNA update function.\nSimilar case is speed effect, where it calculates input frame based on animation, which is integrated over time. Array mapping current to input frames is cached and recalculated in RNA update function." ]

[ "Menus & Context Menus: What to do if operators aren't valid\nThis is a design doc to clarify how we should handle cases where operators aren't applicable. \n\nCurrently, we deal with this poorly:\n\n - In the context menus, we often show properties that won't work (such as when nothing is selected)\n - In regular menus, sometimes operators don't work in certain criteria, but it isn't communicated\n\nHere's how I think we should solve it:\n\n## Context menus\nRule: Only ever show operators here that actually work in the current context.\nThis means that, if nothing is selected, we should not show operators to act on the selection, since this will fail.\nIn general the context menus are always meant to show the user relevant items for the current situation, so this fits with that concept.\n\n**When nothing is selected**\nFor the case where nothing is selected, there often won't be very many applicable operators. In that case, we should add operators to add new items (objects, meshes, strips etc).\n\n## Regular menus\nThese we should keep constant, and not hide or show items, since it breaks muscle memory. Instead, we should use greying out. Preferably we should improve operator polling so that operators get greyed out when not applicable. When nothing is selected, or the wrong kind of item is selected, operatoers that don't do anything then should become greyed out.", "Improve keyboard usage for menu search popup\nNA\n\nBroken: example: 2.78\nWorked: >new feature request<\n\nwhen spacebar search menu popups and user start writing the required command, only down-arrow keyboard shortcut are allowed to select the required command, starting from first item on top.\nIt will be very useful and faster if also up-arrow can be usable to select the last item in the list (so starting from bottom).\nSee image as reference: green arrow show the required feature, red one is the only one actually working.\n\n\nnot an error, only UI usage improvement :)\n", "popup window call operator will crash blender\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.96\n\nBroken: version: 3.2.0 Beta\n\nThis script is use to check the active material, it can be run correct in the main window, but not popup window(change the pref window to node editor)\n```\nimport bpy\n\nbpy.ops.screen.userpref_show(\"INVOKE_AREA\")\narea = bpy.context.window_manager.windows[-1].screen.areas[0]\n\n\narea.type = 'NODE_EDITOR'\nflip_header = True\narea.ui_type = 'ShaderNodeTree'\narea.spaces[0].node_tree = bpy.data.materials['Material'].node_tree\n\nfor region in area.regions:\n if region.type == 'HEADER':\n with bpy.context.temp_override(area=area, region=region):\n if flip_header: bpy.ops.screen.region_flip('INVOKE_DEFAULT') # this line will not\n\n if region.type == 'WINDOW':\n with bpy.context.temp_override(area=area, region=region):\n bpy.ops.node.view_all(\"INVOKE_AREA\") # this line will report context error\n```\n\n- Open .blend file\n- Execute script\n[#98491.blend](T98491.blend)\n\n\n\n", "Move To Line Begin and Reset View operators in the console editor conflict when pressing Home key\nOperating system: Windows-10-10.0.19042-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1650 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.95\n\nBroken: version: 3.4.0 Alpha\n\n\nIn the python console editor, both the Move To Line Begin and the Reset View operators have the same shortcut \"Home\", so it is not possible to invoke the Move To Line Begin operator.", "Tablet/Pen Usability Problems\nFor the most part any user who is using a Pen/Tablet can easily use Blender but there are still a few inconsistencies in the navigation and functions where in the worst case, you need to constantly switch to a mouse.\n\nFor one there is the inability to scroll through certain areas without using the mouse wheel.\nWhen opening a popup list for example when selecting a material, texture, brush, etc, you can only scroll through the window by using the mouse wheel or by typing in the result that you are looking for. But in all other menus that are not popup related, there is the option to scroll by holding the middle mouse button and moving the cursor up/down. \nAdding this option to these popups or at least adding a scrollbar to the side would make it possible for pen users to scroll through these windows without switching to the mouse temporarily.\n\n\nSome tools have a radius that can be adjusted by either using the mouse wheel or using the Numpad +/- keys. \nThis is the case for example in the Circle Selection and Proportional Editing.\nFor pen users the Numpad +/- keys work but are slow and awkward to use because because you have to cross your arms (depending on your layout & right/left handed) and you have to hit the keys in very quick succession for a while or hold it which created a delay of when the scale changes. \nAdding an extra key like using the F key to change the radius in the Paint/Sculpt Modes could be a solution but can be equally awkward and even more confusing to use.

But there are plans to extend this to:\n* Drag & drop\n* #68933 (Collections for Import/Export)\n* Geometry nodes\n* Asset system\n\nFor this we need a unified system to handle I/O for various file formats, to provide consistent functionality across these areas and avoid code duplication.\n\nIt will also make a better user interface for the import operator possible, with a single `File > Import` menu entry where you can then pick a file and see the appropriate options, without having to determine the file format first. Drag & drop similarly should be able to recognize the file type automatically.\n\n## Design Proposal\n\nAdd new `IOHandler` type that can be subclassed, similar to operators or render engines (maybe a better name can be found).\n\nIt would include:\n* List of file extensions (or method to determine if a filepath matches)\n* Method to create import / export settings\n* Method to make UI layout of import / export settings\n* Method to import a file\n* Method to export to a file\n* Method to provide metadata about file\n\nThe precise functionality needs to be determined by looking at the various use cases. But a few general points:\n* Settings:\n**Can be stored as ID properties.** Potentially the defined properties may depend on the use case, for example an import operator may have additional properties relating to how it affects the scene, compared to collection I/O which may be more local.\n* Import:\n** This could work similar to library linking .blend files. That is, importing would populate its own main database with datablocks. The operator, geometry node, assets system would then receive this main database and use, copy or link the datablocks as appropriate for each. This gives each use case more control over the ownership, and by not affecting the main .blend database there should be no side effects from running the import method.\n* Export:\n**Exporters typically export depsgraph evaluated scene data. They also have options for exporting only selections or the entire scene. There is some potential here for an abstraction that provides the relevant subset of evaluated scene data to the exporter, but the right API for this is not obvious.** On the other hand for syncing with Omniverse or other collaborative tools, the data you import and export needs to match, so then you might be exporting original scene data? This might be something we do for USD only and after the basic I/O handler is in place, it's unclear if this would be part of the same system and how it would fit in.\n* Assets:\n**Currently assets must always be datablocks from .blend files, but ideally any importable file would be indexable by the asset browsers as well. For this it's important to be able to quickly read metadata, maybe read or generate a preview image.** Being able to get the file as a set of datablocks in a database could allow reusing existing code more. Even image files could be read as an image datablock for example. However the asset system might already have plans for its own abstractions here, we need to check how it fits.", "Small improvements to 3D View Transform Manipulators\nAs per feedback from the Spring team, we would like to make some smaller improvements to the 3D View transform manipulators:\n\n\n - Increase the treshold for hiding the planar transform widgets, so that users don't accidentally drag the plane when they meant to drag the arrow\n - Increase arrow click threshold. Currently it's very unforgiving. Even if you click outside the arrow by one pixel, it doesn't register as an arrow click. Give it a few more pixels all the way around.\n - Separate the view-aligned rotation handle from the X, Y and Z rotation handles, so that users don't accidentally click the wrong one.

It's standard practice for riggers to make these text datablocks a dependency of the rig to make sure that it's brought along when the rig is appended or linked somewhere. However, such scripts will not run on append or link.\n\nThis introduces a piece of poor UX for animators, which in my experience results in a huge amount of confusion. The animator would have to save and reload the file, or open a text editor and run the script file, but they have no reason to know that they have to do either of these, unless the rigger tells them so. @Hjalti and @PabloFournier probably remember running into this on many occasions.\n\n# Proposal\nMy idea is to add a piece of functionality to the append and link operators; A \"Run Scripts\" bool param, enabled by default, with a tooltip like \"Execute scripts which are set to register on file load after appending/linking\". Can probably come up with better wording, but I guess you get the idea; Appending or linking(directly or indirectly) a text datablock with the register checkbox enabled(`use_module==True`), will also execute it.\n\nIf the user has Auto-Run Python Scripts user preference disabled, it should throw up the usual pop-up to request permission to run the script.\n\nAn example file with a rig and rig UI script, all ready to be linked/appended:\n[custom_rig_ui.blend](custom_rig_ui.blend)\n\nThoughts?

A big reason is that undo writes and reads all datablocks in the file (except from linked libraries). If we can only handle the ones that actually changed, performance would be much improved in common scenarios.\n\nThis proposal outlines how to achieve this in 3 incremental steps. Only 1 or 2 of these steps would already provide a significant speedup.\n\nAt the time of writing there is no concrete plan to implement this, but I've had this idea for a while and it seemed useful to write down in case someone likes to pick it up.\n\n## ~~1. Read only changed datablocks~~ DONE\n\nLinked library datablocks are already preserved on undo pop. We can do the same thing for all non-changed datablocks, and only read the changed ones.\n\nWe can detect which datablocks were changed by checking that their diff is empty. Addition and removal of datablocks also needs to be detected. We need to be careful to exclude runtime data like `LIB_TAG_DOIT` from writing, to avoid detecting too many datablocks as changed. Most changes to runtime data go along with an actual change to the datablock though.\n\nSince unchanged datablocks may point do changed datablocks, we need to reload datablocks in the exact same memory location. We can safely assume the required memory size stays the same, because if it didn't those other datablocks' pointers would be changed as well. In principle other datablocks should not point to anything but the datablock itself, but there may be exceptions that need to be taken care of *(e.g. pointers to [armature] bones hold by [object] pose data...)*.\n\n`Main` fields other than datablock lists may need some attention too.\n\n## ~~2. Optimize post undo/redo updates~~ DONE\n\nThe most expensive update is likely the dependency graph rebuild. We can detect if any depsgraph rebuild was performed between undo pushes, and if so mark that undo step as needing a depsgraph rebuild. This means the undo step is no more expensive than the associated operation.\n\nThis requires the dependency graph to be preserved through undo in scene datablocks, similar to how images preserve image buffers. This would then also preserve GPU data stored in the dependency graph. If the dependency graph supports partial rebuilds in the future, that could be taken advantage of.\n\nThere may be other expensive updates, to be revealed by profiling.\n\n## 3. Rethink how we handle cache preservation across undo steps.\n\n#76989 seems to point to some pointer collision issue, similar to the reason that lead us to add session uuid to IDs when we started re-using existing pointers in undo.\n\nNote that according to the report, there were already issues before undo refactor - hard to tell though if they had the same root cause?\n\nThis needs to be investigated further.\n\n## 4. Write only changed datablocks\n\nWhile undo/redo is usually the most expensive, the undo push that happens after each operation also slows down as scene complexity increases. If we know which datablocks changed, we can only save & diff those.\n\nThis could be deduced from dependency graph update tags. However there are likely still many operations where tags are missing. If it is not done correctly, then instead of a missing refresh there is a more serious bug of not undoing all changes. So this needs verification throughout the Blender code for correct tagging, before it can be enabled.\n\nDebug builds could verify correctness by testing the diff is empty whenever there was no tag.\n\n\n-----------------------------\n\n\nCurrent Status and Plan\n****\n\nThere is an experimental option in 2.83 to address step 1 and (part of) step 2. This was developed in branches and is now in master. Implementation of step 3 has not started.\n\n- [x] [id-ensure-unique-memory-address]() implements the idea of never re-using a same memory address twice for IDs. This is required to allow usage of ID pointers as uids of datablocks across undo history.\n - [x] Add storage of addresses history for each ID (has to be stored in blend memfile, can be ignored/reset when doing an actual blendfile reading).\n - [x] Discuss how to best implement the 'never get same allocated address again' process, current code here is basic, we could probably be much smarter and efficient with some changes to our MEM allocator itself.\n - [x] We are going to try and use session-wise uuids for data-blocks instead.\n - [x] Make new undo behavior controllable from Experimental preferences area.\n- [x] [undo-experiments]() Implements detection of unchanged datablocks at undo, and re-using them instead of re-reading them.\n - [x] Switch to using id addresses instead of names to find back a given data-block across undo history (depends on completion of work in `id-ensure-unique-memory-address` branch).\n- [x] [undo-experiments-swap-reread-datablocks]() implements re-using old ID address even for changed IDs that need actual reading from memfile. Also adds support for more refined depsgraph update flags handling from undo. Both changes combined allow to reduce dramatically depsgraph work needed during most undo steps.\n - [x] Switch to using id addresses instead of names to find back a given data-block across undo history (depends on completion of work in `id-ensure-unique-memory-address` branch).\n- [x] Investigate crashes due to invalid or used-after-free memory in depsgraph after undo step.\n- [x] Investigate why some undo steps are still using full reload of the memfile. Some may be necessary, but think we can improve here.\n - [x] In particular, the absolute last undo step (the first to be undone) is always seen as 'all data are changed', for some reasons...\n- [x] Investigate how to discard runtime data from 'data is changed' detection (probably by nullifying those pointers at write time?).\n- [x] Fix slow undo of adding/duplicating/deleting datalocks. The undo diffing does not appear to be smart to match up the right datablocks in such cases, causing many unrelated datablocks to be marked as changed, which also means excessive memory usage.

I checked the face count and it was just 150k faces which is not a lot at all. It's definitely a modifier problem because when I apply the subd modifier the lag goes away completely even when sliding twice the amount of edges around. I thought that was maybe a hardware issue so I opened task manager and while sliding edges with subd on I get like 4 fps with severe stuttering to top it off. All that while the cpu was at 10% usage and 5% gpu usage with memory barely touched (6gb used out of 64gb). I have nothing else running in the background like an ativirus or music app, I have the latest version of windows 10, latest gpu and chipset drivers, latest bios etc... I even have gpu subdivision enabled without autosmooth to make sure it actually works properly. I even run an sfc/scannow to check for other kinds of issues but nothing changed. Subd in edit mode however is not only slow when sliding edges and vertices but also in adding loop cuts or insetting faces. It is extremely frustrating so it would be great if you could fix this. I know edit mode was not made to handle massive polycounts but 150k is again not a whole lot and definitely comfortable to run on my PC.

I'll link to the pull requests of each individual feature, they don't have much in the way of description and are behind the main build I made, but I will be updating them. \n\n**Edges and Faces**\nAt 0:42 in the video above. \n#109309\n\nGive some options in the keymap for more control over how user can box/circle/lasso select edges and faces. \n\nA dropdown for Edge Select with up to 3 options:\nDefault does Blender does, and Circle doesn't have this option\nTouch will select anything the selection area touches\nEnclose will select edges that have both ends inside the selection area\n\nAll 3 tools have 4 options for selecting Faces:\nDefault does what Blender does\nTouch will select anything the selection area touches\nEnclose will select a face if all their verts are inside\nCenter will select a face if you touch their center\n\n**X-Ray**\nAt 2:38 in the video above.\n#109318\n#109319\n\nBlender doesn't select unseen mesh. You select what you can see. If user wants to box/circle/lasso select something on the other side of a mesh, they'd either turn on X-Ray or move the camera until it's visible. With objects Blender always selects through, and it can't be turned off. Give user control over this, and provide some convenience features. \n\nMake a popover for the X-Ray button. Move the X-Ray settings here from the Shading Popover. Give them new names so it's more clear that wireframe and solid have separate X-Ray properties.\n\nIf user wants to box/circle/lasso select unseen mesh without X-Ray, they can use Select Through. They can decide which tools and modes will use it. \n\nIf they don't want to change how X-Ray affects box/circle/lasso selection, they can use Automatic X-Ray. When they start to drag select it will turn X-Ray on, and when the selection is done X-Ray will turn off. They can decide which tools and modes will use it. \n\nInclude some operators. User can show any combination of them in the Header. If everything necessary for the tool and mode is enabled, the button for the operator will be lit up. It's modular, so there are many ways for the user to setup their shortcuts. Make new icons for Auto X-Ray and Select Through, the ones in my build were made by Alexey Adamitsky.\n\n**Viewport Facing Select**\nAt 4:17 in the video above.\n#109357\n\nBlender _does_ select unseen Mesh, and not in a good way like Select Through. If user can see some verts of an edge or face, they're potentially selectable regardless of their visibility. If it isn't truly random which unseen edges and faces this applies to, it may as well be. The 3 drag selection tools select the same wrong things, but if the viewport camera is moved or rotated, this will usually mean that different unseen edges and faces are now selectable.\n\nThe opposite is also a problem, where user cannot select visible mesh. If user zooms out, has a complex mesh, or a shallow angle on it, selection bitmap will only capture some of the mesh and give a patchy bit of what the user wanted. Long term, need to increase resolution of selection bitmap, whatever that would mean. Maybe Vulkan affects this in a positive way, maybe it has nothing to do with it. \n\nFor now I made Viewport-Facing Select to deal with this. Put it in Toolsettings. It works in near select, X-Ray, or both. When user drag selects with box/circle/lasso, it compares mesh normals to the viewport. If they aren't facing each other within the threshold, they won't be selected. Has a range from +/- 0.999999. Greater or equal to 0 means the mesh normal is pointed in the direction user has it set to. The higher they set the threshold, the more the mesh needs to be facing in that direction. A value of 1 should mean the viewport and mesh are aligned, but was only working from the front perspective (numpad 1) and from nowhere else regardless of ortho. Max threshold of 0.999999 is functionally the same as having it at 1 except it works from any angle. Negative values can select unseen mesh.\n\nAll Verts setting saves performance without compromise, because Blender doesn't select unseen verts. They're dimensionless, and since there's only one position for them to be drawn in, they shouldn't be in the selection bitmap unless they're visible.\n\nFront Verts will select verts based on their normals,. Some of the verts at the edge of a mesh are excluded. Verts of Front Face will fix that, it selects verts if they're part of a face with a viewport facing normal. There's also rear facing counterparts to these, they do the opposite where they'll select stuff pointed away from the viewport. Not sure if they're useful but it's easy to include.\n\nThe settings for edges work the same as verts. Using edge normals will exclude things the user probably wants to select, and Edges of Front Face will correct that. Same goes for face settings, except Front Faces are what give accurate selection. Faces of Front Vert will select faces that have at least one vert with a viewport facing normal. This means it can select unseen faces, which is what I'm trying to avoid, but maybe it's useful for something.\n\nSometimes user will be able to see a face even though it has a rear-facing normal, and VFS won't select it. Usually this is because they are dealing with two triangles that have no business sharing the same quad, but that's going to happen from time to time, and they'll need a way to select them. Besides turning this feature off temporarily, triangulating or otherwise fixing the mesh, single-clicking, or rotating the camera, they can drop the VFS threshold into the negative. How negative they go depends on what they're willing to live with, and it gets worse the lower they go. I keep it at zero, because at least I have a chance of noticing things I didn't select. Hard to keep track of random selections that you can't see. It's not perfect, but it's predicable, and should work with most geometry.\n\n**Object Origin**\nAt 7:35 in the video above.\n#109373\n\nMy implementation of this feature is incomplete, but functional. Circle and lasso are forced to select objects by their origin, while box cannot do this. Put a checkbox in the Keymap so user can control this. Call it Select Object Origin. With my build box origin seems ok, but circle is a little off and lasso has enough problems with non-origin that I left it out. There's an addon that does this fine though from what I've been told. I looked at it but I couldn't figure out how to give object mode access to vert info, just kept getting errors so I left it at that for now. Addon is called [X-Ray Selection Tools](DaLdj)\n\n**Unsolved Mesh Select Issues**\nAt 8:32 in the video above\n\nIntersect doesn't work with Touch or Enclose face in X-Ray and Select Through. Don't know why, looked at it a few times, doesn't make sense to me. With my build it will fallback to a Center select instead. Figured it's better to do something close to what is expected rather than nothing.\n\nEnclose face works in near select, but it's hard to use if user can't see all the verts of a face. If there is a visible face, but some of it's verts that would otherwise be on screen are behind something else, the selection bitmap thinks they don't exist. This means that it also thinks that part of these faces are outside the selection area, even though they aren't, and they get excluded from selection. One thing user can try is avoiding the selection bitmap entirely. Turn on Select Through, and set Viewport Facing Select to work in X-Ray, Verts of Front Face, Edges of Front Face, and Front Faces. Threshold at zero is best in my opinion. Now they get a decent result, but have to deal with the baggage that comes with Select Through and VFS. They don't always get everything they can see, at least when encountering some weird faces that have triangles pointing in very different directions. Also, they're going to select like X-Ray so if there's something that is facing the viewport, but they don't have line of sight, they're going to select it without actually seeing it.\n\n**Drag Direction**\nAt 9:56 in the video above.\n#109726\n\nBlender let's you assign a direction to click-drag in the Keymap. There are 8 of them, which is nice, but it's confusing and inaccurate if all you need are 2. Provide some alternatives in Preferences->Input->Mouse. I'd like to put them at the top of the keymap in that preferences area, but I noticed how that thing will disappear if you load a keymap or use one other than the default. Didn't look into it yet. \n\nKeymap Drag Direction has 3 options. Eight, which is what Blender does, Left Right, and Up Down. The tradeoff for the new ones is that they're exclusive. If you use Left Right, the only Keymap items Blender will match with are Any, Left, and Right. Unless something has been manually set to a direction, there shouldn't be anything besides View Axis, the ones where you hold ALT and Middlemouse while dragging in the direction that corresponds to the view you want.\n\nWith Blender's way, try to set Box select to Extend when dragging left aka West, and Subtract when dragging right aka East. If user doesn't initiate a mouse drag within 45 degrees of left or right, they get a Tweak Event instead of what they expected. There's a way to make this work better using the keymap alone. They can set Extend to Any, and Subtract to East, Northeast, and Southeast. The Keymap item set to Any needs to be after the other 3 or they'll be undetectable. Not intuitive, and I didn't figure out this was possible until after making this feature.\n\nWith the new ways I made there's 3 operators that will set drag direction. If a Keymap item is undetectable, it will warn the user about it. Not ideal, but nothing bad will happen, it's just telling them that this Keymap item won't do anything because Blender can't see it anymore.\n\nDrag detection has some perpindicular bias. If the user is on the Left Right setting, and they drag up or down far enough before moving to the right, they're going to get the Left Keymap item instead of the Right Keymap item that they intended. If they're on Up Down, and move horizontally before going up, they would get the Down Keymap. With Blender's Eight way, assuming they set it like I described, the dominant Keymap item is the one that is set to the Any direction. The Left Right and Up down options are a lot more precise so it's hard for this to happen. The Eight way calculation rounds to the nearest int, so it treats every mouse drag within 45 degrees of a cardinal direction like it went straight vertical or horizontal. This problem can be mitigated by increasing drag theshold in Userprefs->Input->Mouse.\n\n**Selection Radius**\nAt 12:48 in the video above.\n#109729\n\nSingle-click an edge, vertex, or facedot and there's a pretty big area the user can grab it from. Faces in near select have zero radius, so the cursor needs to be right on top of them. Make this adjustable and consistent. Preferences->Editing->Miscellaneous-> Adjustable Click Select is where I put it, but that is not a good spot. It makes faces act the same as the others, and the user can change the size of the selection radius. Blender gives unselected mesh a slight bias, this can be turned off. Very minor detail that would not likely be noticed.\n\n**Conclusion**\n Nothing is really done all the way, but it is closing some gaps. Lot's of things can be moved, renamed, tweaked. That's what I'd like to do, and maybe some of it can make it into real Blender.\n\n", "Wire objects that are being displayed on front only updates visibility after interaction\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.14802 Core Profile Context 22.2.1 30.0.14023.7007\n\nBroken: version: 3.2.0 Alpha\n\nThis problem is similar to the one found in #84717, but in this case it is only affecting objects that are marked as in front and wired mode.

If face dots are visible in x-ray, they should be used for selection in box/lasso/circle. If facedots are not visible, use the alternative selection via their \"face area\" for box/lasso/circle. \n\nProbably don't carry this logic over when Xray is disabled though, because enforcing solid facedot select in this manner would disrupt the established method of \"face area\" selection in when Xray is disabled.\n\n# Open Questions\n\nDisabling facedot display in x-ray leads to at least two questions:\n1. Do you have two facedots (solid and xray) so that they can be toggled separately? I think this is good because it means if you want them on in xray only, and not in solid, you don't need to toggle them when going between solid and xray.\n\n2. Is the ability to disable xray facedots, and the alternative face area select in this mode, worth the potential confusion introduced for single click face select? \n\nI can't think of another way to select faces by single click in xray. So potential for not seeing facedots, and then needing them for single click, leads to some issues. If user wants to use the alternative \"face area\" select in x-ray, they will no doubt need to single click on faces in x-ray as well. I think another way to do this could be that instead of linking facedot selection with their visibility, we could have a checkbox somewhere like toolsettings. Or directional based (dragging clockwise vs counterclockwise or left/right) to choose either facedot or \"face area\" is also a pretty cool idea. This way you don't need to have facedots turned off to use the \"face area\" method, which alleviates some problems for single click selection of xray faces.\n\nOne more thing to consider is adding facedot selection to solid shading, this has some usefulness:\n514?u=lcas", "Improve Interior Face Selection Method #2\nOperating system: Win 10 Pro\nGraphics card: nVidia GeForce GTX 1070ti\n\nBroken: tested in 2.80 stable and 2.81-dcad1eb03ccc\n\n\nIn Edit Mode Select -> Select all by Trait -> Interior Faces does not select all expected Faces.\n\n\nIn the attached blend file try to select the interior faces by trait and nothing happens.

In the modal operator equivalent (Shortcut C) it's just about pressing + and - or using the scrollwheel but this is not an option for the Tool. Generally there are no shortcuts for Tools before they are initiated. If the settings need to be changed then this needs to happen in the Tool Settings in the header or sidebar.\nBut changing the radius via that slider in the settings is awkward and appears visually glitchy since it's intersecting with the UI itself.\n\n\n\n## Proposals\n\nSo how can this be fixed. Ideally the solution should be as straight forward as possible without reshuffling the keymap. But it is very important that this is a general solution that can also be used for other brush-like Tools in the future (like proposed retopology tools that also rely on a brush radius)\n\n**1. More integrated modal shortcuts**\n\nOnce a Tool is initiated (usually by click & dragging) it uses the modal operator. This means that when using the Circle Select Tool and click & dragging, the radius can be changed with the mouse wheel & the + and - keys. \nThe current issue with this is that the Gizmo drawing is conflicting with the Tool Radius and that any changes to the radius are not updated in the tool settings.\nKeeping these 2 more in sync would be one solution or at least a great added feature.\n\n\n\nIt should be updated to the way the annotate eraser tool works but with more accessible shortcuts for radius changes if the mouse wheel is not an option (pen users)\n\n**2. Include Brush Tools in more modes**\n\nAnother solution is to redesign the Circle Select Tool (and any tools, present or future, that work similarly) as a brush like in sculpt mode or the painting modes.\nThis means that when the Tool is active it does have a set of shortcuts that can change the tool settings before the tool is initiated.\n\n**Conflicts**\n\nAlmost all are already taken like the typical F for brush size changes. It's not clear what shortcut can be used. \nAlso any shortcut that would be available must then be exclusively used for those brush tools to avoid any conflicts. \n\n**Solutions**\n\n1. Find or make an available shortcut for brush tools radius. But this shortcut then needs to be left exclusive of those tools.\n2. Override needed shortcuts when brush tool is used (In this case F for the radius). This does introduce difficulties and extra tool switching in edit mode though. \n3. Reuse the shortcut C that is used for the Circle Select Tool to change the radius once the tool is active. This will be awkward and incompatible with future tools that will work similar though.\n\n## Open Topics\n\n- Can it be achieved to use both solutions to improve brush like tools?\n- Are there possibly other ways of solving the conflicts in proposal 2?\n- For proposal 1, what shortcuts could be better for adjusting the brush size? + & - are on the numpad and the brackets are too far to the right and on for example German keyboard layouts not very accessible.", "Outliner Sync Selection: Use general update method\nCurrently there is a callback to flag the `wmWindowManager` as needing selection to sync to the outliner `ED_outliner_select_sync_from_object_tag`.\n\nUsing this requires us to explicitly tag on any selection change.

This only works well for mesh and grease pencil edit-mode, however it has some down-sides.\n\n- We would be using all number keys by default, any additional modes or sub-modes wont fit.\n- Some sub-modes wont fit:\n - Particle edit (currently uses keys 1-3 to switch sub-modes).\n - Weight paint.\n - Texture/Vertex paint.\n\nThe ideal solution in this case isn't clear, either we accept loosing shortcuts for switching sub-modes or accept some inconsistency (having to add a different shortcut for sub-mode switching for modes besides edit-mode).\n\nThere are plans to merge painting modes into a single attribute painting mode, even if this is done, it might make sense to expose weight/texture/sculpt as sub-modes... either way, I don't think we should rely on this change unless it's committed to master before the keymap changes. The same applies to the future of Particle Edit once the new Hair object type is implemented.\n\n**What to do when pressing a modes key a second time?**\n\nCurrently nothing is planned. Options are to toggle the mode or cycle through sub-modes. Both have their pro's and con's so there are no plans to use second-time presses.\n\n**Is overwriting edit-mesh modes acceptable?**\n\nBy switching directly into vert/face/edge modes, this will overwrite the mixed modes which the user will need to manually set every time they enter edit-mode. Holding Shift while changing selection modes will extend the selection as it does currently.\nEven though this isn't such a common functionality, it would be good to avoid breaking peoples workflows.\n\n----\n\n*Updated by @pablovazquez based on notes from the UI meeting on 20 May.*", "Linked data-block has \"pointer\" property still active\nBroken: version: 3.4.0 Alpha, branch: Unknown, commit date: Unknown Unknown, hash: `rBUnknown`\nWorked: Probably never\n\n\n\n[torus.zip](torus.zip)\n\nOpen torus.blend.

Texture nodes can be though of as a geometry nodes field, and when evaluated in the context of geometry nodes they are.\n\nHowever they can also be evaluated outside of a geometry node tree. In particular, they can be evaluated on:\n* Geometry domains vertex, edge, face, corner, for geometry nodes and baking of textures to attributes. Possibly also sculpting and vertex color painting.\n* Geometry surface, for image texture baking and painting.\n* 2D or 3D space not attached to any geometry. For brushes, 2D image painting, physics effectors.\n\nTo support the last two cases in the geometry nodes infrastructure (but not the geometry node evaluation itself), a new field context named `TextureFieldContext` is added. This represents a continuous texture space, that may be mapped to a geometry surface or not. It has one domain, `ATTR_DOMAIN_TEXTURE`.\n\n**Compilation and Execution**\n\nThe texture nodes compilaton and evaluation mechanism uses much of the same infrastructure as geometry nodes, but is separate to be usable in different contexts. It's meant to be possible to execute texture nodes efficiently many times, for example paint brushes are multi-threaded and each thread may execute the nodes multiple times. This is unlike geometry nodes where multiple threads may cooperate to execute nodes once.\n\nThe current compilation mechanism is as follows:\n* Multi-function nodes are compiled into a `MFProcedure`, which bundles multiple multi-functions into one for execution. Geometry nodes do not currently use this mechanism, but it is designed for this type of evaluation. This is rather inefficient currently for individual points, but should get more efficient when evaluated in big batches.\n* Remaining nodes are input nodes, and execute `geometry_node_execute` as part of compilation, which then outputs fields and values. The execution context for these nodes is limited, unlike geometry nodes there is no geometry, object or depsgraph.\n* For evaluation, fields are converted into `GVArray` using the provided geometry.\n\nWe could consider making geometry available and to the compilation and caching the compilation per geometry, though it's not clear there will be nodes that need this. Alternatively we may cache just the `GVArray` per geometry.\n\n**Fields**\n\nInput nodes return fields, which are then turned into `GVArray` for evaluation. For the texture domain, this is a virtual array that interpolates attributes. There may be some possibility here to share code with data transfer field nodes, or nodes that distribute points and curves on surfaces and inherit attributes.\n\nShader nodes need additional fields that are not currently in geometry nodes:\n* Generated / Rest Position / Orco\n* Normal, taking into account face smooth flag and custom normals\n* UV maps (planned to become available as float2 attributes)\n* Active render UV map and color layer\n* Tangent\n* Pointiness (Cavity)\n* Random Per Island\n\nIt's unclear to me what the best way to specify these as fields is, if we should add additional builtin atttribute names or `GeometryFieldInput`. Some of these like Pointiness would also make sense to cache as attributes, and make available to external renderers.\n\nOne constraint is that it must be efficient to evaluate only a small subset of the domain. For many field inputs and operations this works, but there are some that will compute a data array for the entire domain. This can be enforced by just not making such nodes available as texture nodes, or caching the data array on the geometry.\n\nFor sculpt and paint modes, there is a question if and how we can make all these attributes available. The challenge is that it has different mesh data structures (bmesh and multires grids), which are not supported by geometry nodes. Additionally, recomputing for example tangents and pointiness as the geometry changes during a brush stroke would be inefficient, especially if it's for the entire mesh and not just the edited subset.\n\n**Batched Processing**\n\nFields and multi-functions are not optimized for evaluating one point at a time, there is too much overhead. That means we want to process texture evaluations in batches, and all (non-legacy) code that uses textures should be refactored.\n\nFor geometry nodes, modifiers and 2D brushes this is most likely straightforward. However for 3D brushes, particles and effectors it will be more complicated.\n\nThere is currently a mechanism to single evaluations possible while code is being converted. However this is rather inefficient, with quite a bit of overhead in `MFProcedure` execution. It may be possible to do some optimizations there for legacy code that we may not be able to easily convert to batches.\n\n**Node Graph Transforms**\n\nTo support sockets like Image datablocks, and to automatically insert Texture Coordinate or UV Map nodes for textures coordinate sockets, we need to transform the node graph. The texture node layering will also need to do significant node graph transformations. In order to share code with Cycles and other external engines, it may be best to do this as part of node tree localization.\n\n**Relation to Other Node Systems**\n\nThere are many node evaluation systems in Blender, and the question is if we can somehow share this implementation with anything else. I don't think the CPU evaluation can be directly shared, but will make the old texture nodes evaluation obsolete at least. The GPU implementation can probably be largely shared with shader nodes, and that implementation could be refactored to use DerivedNodeTree for consistency and to simplify that code.", "Geometry Node in World Shaderworkspace does not output the same coordinates in Eevee like in Cycles.\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.27\n\nBroken: version: 3.0.0 Alpha\nWorked: None same in 2.83\n\nGeometry Node works differently for Cycles and Eevee in the World Shader Tab, The Coordinates are distorted with Eevee.

They are left as floating particles which is a big issue for final renders with posed characters/objects. \nFurthermore, if the surface mesh is subdivided, more curves appear that do not pose with the mesh correctly and instead stay in rest position, however these are not considered an \"invalid surface UV attachment\", and thus cannot be removed with the 'hair attachment info' node's selection.

Some use cases for it could be:\n\n- Editing IDs on face corners to modulate materials in a shader\n- Painting velocity vectors on vertices to guide a particle system\n- Editing the weights of a rig\n- Editing per face colors for low poly models without using textures\n- Setting custom values on edges for a motion graphics animation\n- Modifying mesh values for procedural modeling\n\nSome of these task could use a brush, but they don’t need a brush with artistic painting functionality. It does not make sense to edit the weights of a rig with a brush with wet paint and density noise.\n\nFurthermore, these task could take advantage of a mode with more control and precision tools than an artistic painting mode, like precise elements selection and data editing, controlled value interpolation…\n\nThe plan is to use the current Vertex Paint mode as a base implementation for this mode and start adding all necessary features during multiple releases. It already has quite some work done because most users were using it with these use cases in mind.\n\nThis task is not as detailed as the Sculpt/Paint mode, but it should be enough to have an idea of its purpose, use cases and design goal.\n\n### Tools\n\n**Simple brush tools**\n\nThe current Blender brush functionality is enough to support this kind of painting, if we consider painting changing the values of elements that are inside the cursor radius. We can reuse the current brush code for that.\n\n**Value interpolation tool**\n\nThis tool could produce controllable interpolations of an attribute between two mesh elements following the mesh topology. For example:\n - Select the base of a cone and assign the value of one \n- Select the top vertex of the cone and assign 0 \n- Let the tool generate the rest of the values across the cone surface\n\n**Mesh elements selection**\n\nAttribute paint should provide tools for selecting mesh elements and assign values directly to them. This provides much more control than a brush. This could be useful when working with low poly models, where you want to assign values like armature weights in a precise way.\n\n**Mesh element masking**\n\nWe can support a basic masking functionality for the brush that supports all mesh elements (not only vertices like the Sculpt/Paint mask). This can make easier some painting task.\n\n### Features\n\n**Data conversion operators**\n\nAttribute edit mode should provide a set of conversion tools to convert data between elements and other Blender data layers when possible. For example:\n\n- Convert a per vertex attribute to a per face corner attribute\n- Convert a per edge attribute to a vertex attribute averaging the\n```\n values\n```\n- Generate material slots from an ID attribute stored on faces\n- Generate an editable 2D vector attribute from an UV layer\n\n**Per face corner color data to sculpt/vertex color data**\n\nThis is a specific case of a conversion operator. Other conversion operators can be added in the future as we support more attribute types.\n\n**Internal attribute conversion**\n\nWe need to identify what element/attribute type conversion combinations are more frequent and design how they can work (usually averaging the values). For example\n\n- Converting an attribute from face corners to faces by averaging the\n```\n values of all the face corners in the face\n```\n- Converting from vertex to edges by averaging the value of the two\n```\n vertices of the edge\n```\n- Converting from vertex to face corners assigning the same vale of\n```\n the vertex to all the face corners that use that vertex\n```\n\n**Topology symmetry**\n\nWe could support editing operations with symmetry based on the mesh topology instead of mirroring the XYZ axis.\n\n**Attribute data type selection**\n\nThe use should be able to choose what kind of data he/she wants to edit and in which mesh element that data should be stored. For example\n\n- A float factor stored on faces\n- A vector stored on vertices\n- A color stored on face corners (Current supported MLoopCol)\n\nAll tools should be aware of the data type of the layer and behave accordingly.\n\n**Import/Export**\n\nIt should be possible to import and export meshes with different attributes in mesh elements. We need to check format compatibility.\n\n### Rendering\n\n**Attribute edit overlay**\n\nAs we can make assumptions that the attributes are colors, we need to render a configurable overlay to display the data in an appropriate way.\n\n**Attribute rendering mode selector**\n\nThe attribute rendering overlay should provide and UI to choose which rendering mode the user wants to render the data. This should include tools like a gradient editor, rendering two attributes at the same time, render vectors and randomly generated ID maps.\n\n**EEVEE/Cycles attribute node**\n\nThe current attribute nodes exposes MLoopCol and UVs to the render, which are both loop attributes. We need to investigate how to expose face, vertex and edge values.", "Moving reroute nodes with click-drag behaves unpredictably\nOperating system: Windows-10-10.0.19042-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 496.76\n\nBroken: version: 3.1.0 Alpha\n\nThe recent builds of Blender 3.1 add an option to finally move reroute nodes with mouse only, like any other node types.

I often I solidify and displace surfaces in the processes I work on -- recently for 3d printing custom assistance devices including molds for casting rubber, customized computer peripherals, etc. Whether or not they use clear-cut geometric forms, or are of organic nature, they often succumb to the issue of intersections with displace/solidify. I've wanted to work out some details on processes which would enhance these modifiers, but need some help. I'd attempt to implement it so it would be inactive normally, and use thresholds when enabled, so as not to slow down the normal modifier functionality, and a require a minimum processing when the features are used.\n\nThe main issue I'm having is that the modifiers do not presently have access to information on adjacent vertices, and my first approach to an algorithm would examine, with some function fn(vertex_normal, displacement_amount), if there would be a crossing (e.g. if faces would intersect).

Refresh states not working automatically from outliner in some cases, save/open file again solving problem.\n - also suggestion is to hide all child objects in parent when parent status is changed to hide to not child one per one, or give to hide just this object (eg. contex menu by RMB)\n - this management can solve problems around operation as in point 1,b) issye\n\n2. When refresh states not working on timeline and when just animation refreshing coordination **not when objects are moved,**etc. (just play changing eg. x,y,z on this same frame in case operations as move, scale, rotate not doing this - so backing to main frame when was operation, update etc. not giving effect, just play)\n - for both solution is suggestion to **give option for viewport rendering** as this same like final render, regarding the states and depth levels of parents/child/collections \n\n\nMaybe is know issue, maybe some on meet this and can explain better than me, or some part of code can be checked to see relations for this type issues.\n\n</details>", "Shading change (smooth/flat) resets current simulation cache. \nOperating system: Windows-7-6.1.7601-SP1 64 Bits\nGraphics card: GeForce GTX 660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.19\n\nBroken: version: 2.83 (sub 5)\nversion: 2.82 (sub 7)\nWorked: 2.79\n\n[2020-02-26_04-40-40.mp4](2020-02-26_04-40-40.mp4)\n\nSet simple simulation, play it (to the end or pause), change shading to smooth/flat.

These will just be referred to as *thing* in this task to avoid having to repeat that entire list.\n\nThe *Selected* and *Active* states are independent, so there are four states a thing can be in:\n\n| | Not Selected | Selected |\n| -- | -- | -- |\n| Not Active | x | x |\n| Active | x | x |\n\n**Problem**\n\nThere are two states possible that can cause issues:\n1. **There are *Selected* things, but none of them is *Active*:** a sidebar/numerical/properties panel will not show information, and generally be empty without explanation why.\n2. **There is an *Active* thing, but it is not *Selected*:** this is not shown in the UI, as there is no separate color for this situation; all *Active* things are shown the same way regardless of them being *Selected* or not. This causes confusion and unexpected behaviour, and also doesn't allow for an actual clear use of this possibility.\n\n**Related Reports**\n\nThese reports are examples of confusing situations where the disconnect between *Active* and *Selected*.

If there are *Selected* things, there is always one of those that is the *Active* thing.\n2. If a thing is *Active*, it is also always *Selected*.\n\n**Hurdles to Overcome**\n\nRule 1. above requires that one of the selected things is marked active. There is not always a unique, obvious choice here, for example when box-selecting multiple things at the same time. In this case the choice should at least be consistent so that users know what to expect after a while. The thing closest to the mouse cursor (when using the mouse to select) could be a reasonable choice.\n\nRule 2. above can be dealt with in various ways:\n- Create a function that returns the *Active* thing, and make it return nil when that thing is not also *Selected*. This is what was implemented for the Active Keyframe (983ad4210b). This has the downside that now nothing is active, breaking rule 1 and forcing the selection-changing code to pick another thing to become *Active*.\n- Refuse deselection of the *Active* thing.\n- ... something more elegant.\n\n**Goal of this Design Task**\n\nThe goal of this design task is to answer the following questions:\n- Is there an agreement that the current situation causes issues, and that having a stronger correlation between *Active* and *Selected* is a good thing?\n- Is there an agreement that the proposed two rules are the way to go?\n- How do we implement these rules in a way that makes sense to artists?\n- Can we implement this in a way that can be reused by all the affected parts? Some unified selection/activation API that can be implemented for different data types?\n", "Keyed Particle Physics Incorrectly Rendered Under Eevee and Cycles, but Correctly Rendered in Viewport Render\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: Radeon RX550/550 Series ATI Technologies Inc. 4.5.14736 Core Profile Context 20.8.3 27.20.12027.1001\n\nBroken: version: 2.91.0 Alpha\nWorked: Never (2.80+)\n\nCreate two objects.

Therefore, particles should move from the first object to the second object. If the starting velocities are non-trivial and the keyed particles are generated over three or more frames (e.g., start time 10, end time at least 12) then the particles of the keyed system are correctly rendered in the viewport (rendered mode) but appear in different positions when actually rendering (pressing F12).\n\nI first discovered this with a more complicated example, and the same behaviour occurred under both 2.90 and 2.83 (normal releases). Googling did not turn up anything relevant. (Motion blur is off.)\n\nI have been able to recreate it with a simple .blend file attached. Included are two screenshots at frame 20, one of the viewport, one of the rendered image. While the difference is just one particle here (a red particle is over the left square in the viewport but off the square in the rendered image), vastly different behaviour can be achieved by increasing the difference between start and end times. \n\nIn the more complicated example, not included here, a particle would appear at the top of the screen and move towards its final destination. When rendered though, it would appear in the correct place on that frame but then immediately jump to a very different location on the next frame.\n\nNote: This bug might depend on the first object's particles having a short lifetime - the original motivation is having one object explode then morph into another object.

In the ui it will be called `Hair Curves` for now to distinguish it from the old curve type. \n* - [x] Decide on and implement exact data structure used for curves.\n * Should be stored compactly in continuous arrays.\n * Should support arbitrary attributes on points and splines.\n * Ideally, the actual curve data structure is embedded into the `Curves` data block as a separate struct, so that the same struct could e.g. be used for grease pencil.\n* - [x] Refactor geometry nodes to use the `Curves` data block instead of `CurveEval`. (#95443)\n* - [x] Remove the runtime-only `CurveEval` data structure added for geometry nodes.\n* - [ ] Render geometry nodes curves as with the new type in Cycles and Eevee (#96455)\n* - [x] Curves sculpt mode that is mostly focused on hair use cases\n* - [ ] Curves edit mode, similar to existing curve edit mode\n\nFurther in the future:\n* - [ ] Add existing necessary features from the legacy curve object (features like shape keys may add complexity)\n* - [ ] Use versioning to convert legacy curve objects to the new curves object\n* - [ ] Add support for simulations through a generic simulation system involving geometry nodes\n* - [ ] Use versioning to convert hair particle systems to the new curves object\n\n", "Cycles: Refraction shaders work incorrectly with normals as mesh attributes\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.94\n\nBroken: Last main.\nWorked: Never?\n\nNormals created as Normal input node in Geometry Nodes.

So we still need some ability to make normals more custom.\n\n**Option 1: Custom Normals**\nOne solution is to use a \"Set Custom Normals\" node. However, that requires accepting that the normals might not be orthogonal to the tangent, or making it a lossy operation.\n\n**Option 2: \"up\" Attribute**\nAnother option is adding another attribute that influences the automatic calculation of normals like `tilt` does currently.\nThe `up` attribute would be an initial starting direction for the normal.

The vertices created by the by the bisection are mapped to the original mesh data in a way that appears to be based on blenders internal representation of the mesh and not based on something observable to the user.\nThe behavior when selecting should feel consistent to the user. To fix this, I suggest that the vertices created by the bisection should always map to the vertices on the original mesh that are on the removed side of the bisection plane.

The linked bug is closed as a presumed limitation of Grease Pencil.

Namely, \"the strokes are always drawn as a billboard face to point of view\" prevents them from looking flat, despite being drawn with a brush defined in 2d space.\n\nI do not know Blender internals, but visually it looks like the problem is elsewhere: blending of colors in \"Stroke Depth Order: 3D Location\" binarizes (at least in some cases) the brush' alpha (opacity) channel.

Often I get \"out of memory\", but that is only because Blender does not dump some things from memory before viewport rendering an updated scene. It's bound to be a known issue and easy to work around.\n\nI have prepared the file to upload here, but it's 1.9 Gb zipped. Before I send it there maybe some advice about troubleshooting my end someone might know and can help me with. I have spent 3 solid weeks trying to troubleshoot this and the only reliable way I know of reproducing the issue is with the full file.\n\nN.B. The update to 3.6.1 saw me return to this with an updated and improved version of the file. Background rendering will SOMETIMES render problem frames. I have included debug files for this as well.\n\nIs there any advice I can get as to how to narrow down this problem?\n\n", "Viewport Compositor: Render passes support\n# Scope\n\nThis design task describes integration of multiple render passes of the same view layer to the viewport compositor.\n\nWhile ultimately multiple view layers would need to be supported as well, it will be handled separately as there more design considerations to be solved to keep performance and memory usage under control/\n\n# Overview\n\nThe overall overview of the proposal is quite simple:\n\n- Render engine provides GPU textures for all render passes.\n- The compositing is done by the draw manager from the Blender side.\n\n# Breakdown\n\n## GPU texture management\n\nThe render engine manages GPU textures on the engine side, and allows them to be bound for the viewport compositor shaders. This allows the engine to have full control over data management and synchronization for updates. For example, it allows engine to do proper initialization order for the graphics interoperability.\n\n## Overlays\n\nSome of the data which a render engine wants to visualize does not fit into the compositing pipeline, and is better suitable as an overlay. On example of such visualization is the `Active Pixels` (available with `Cycles Debug`).\n\nSuch overlays will be moved from \"being\" baked into the combined pass and instead will become a dedicated call in the render engine `draw_overlay()`.\n\nOn the render engine side it will behave the same way as the current `draw()`: \"just\" draw a texture(s) with overlays.\n\n## Data structures\n\nThe proposal is to base the data passed in the API on the `RenderResult`, and not to create a dedicated specialized data structures. This will allow maximum code re-usaiblity between the viewport, viewport compositor, final renders, and eventually GPU compositor for the final renders.\n\nThere are changes which needs to be done in the `RenderResult` in order to support this, with the final goal is to allow `RenderResult` to point to a GPU texture instead of CPU-side memory buffer. The proposal here is to:\n\n* Make `RenderResult` to use `ImBuf` to store passes data.\n* Make `ImBuf` to have GPU texture without CPU side buffer.\n\nConsiderations for such decision:\n\n* The `RenderResult` is heavily integrated into the image drawing (for the `Render Result` image data-block, multi-layer EXR images). If the `RenderResult` stores data as `ImBuf` then it will simplify drawing, which will no longer need to do shallow copies.\n* The `Image` data-block already uses GPU textures, which can be moved to the `ImBuf`.\n\n## Synchronization\n\nUpdate of the GPU texture and its use by the draw manager happens from different thread, . This is already the case where `DisplayDriver` takes care of synchronization.\n\nTo start with the synchronization strategy will not change:\n\n* The render engine will lock the GPU textures at the moment when it knows its internal render buffer is in a consistent state (in case of Cycles: when the entire wavefront finished sampling), and will copy data to the GPU textures.\n* From within the same lock the render engine will copy data needed for the overlays.\n* Once the data is copied, the render engine releases the textures lock.\n* When draw manager requests `RenderResult` it will lock the textures, and will hold the lock until the drawing and compositing pipeline is finished.\n\nThis potentially introduces wait-on-a-lock for the render thread: if the compositing takes longer than sampling.\n\nWhen CPU rendering is used it is relatively easy and beneficial to allow \"interleaving\": render more samples while the draw manager is still busy with compositing. In the case of Cycles it will mean that the `PathTrace` will need to take time spent in drawing into account and schedule more samples to fill it in.\n\nFor the GPU rendering the story is more complicated:\n\n* If the rendering and compositing done on the same GPU the interleaving might not be desired at all, as a lot of supported GPUs do not allow interleaving GPGPU and viewport rendering without performance impact.\n* If the rendering is happening on a different GPU than viewport rendering then interleaving is possible.\n\nFor the latter either engine could do a guess which GPU is used for viewport, or it would need to be a dedicated API call to provide this information explicitly.\n\n## Used render passes\n\nCurrently for the viewport render the used render passes are in the full control of the render engine. This needs to be changed to something:\n\n* Render engine provides list of supported render passes\n* The viewport compositor provides information which of them are actually needed for the viewport\n\nThe former is probably already covered with the render passes integration used to create sockets in the Render Layers nodes.\n\nThe latter one is needed to make it so unused passes do not take memory: for example if some passes are only used to write to file.\n\nThe render pass display option (currently available in Cycles, and allows to choose which render pass is displayed in the viewport) will behave more like it does in the Image Editor where it is possible to choose between Composite output and View Layer / Passes, can then can work for any render engine.\n\n", "Crash Guide during render complete 2 December 9, 2022\nOperating system: macOS-13.1-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 575 OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.9.51\n\nBroken: version: 3.4.0\n\nCrash Guide during render 2\n\nSame crash guide during render before and today.\nSee youtube: ZeCA2p5wISY\n\nHistory previous.\nT100691\n\n\n\n\n[Blender-2022-12-09-161546.ips](Blender-2022-12-09-161546.ips)\n\n[Horizontal Video.zip](Horizontal_Video.zip)", "Blender 3.6.3 SegFault Crash at startup on MacOS Ventura 13.5.2\nOperating system: MacOS Ventura 13.5.2 (22G91)\nGraphics card: Intel Iris Plus Graphics 650 1536 Mo\n\nBroken: 3.6.3 (3.6.3 2023-09-21)\nWorked: None tried on this machine\n\nCrash on startup with `Segmentation fault: 11`\n\nEither:\n- Double-click on Blender application icon\nOr:\n- command line : `/Applications/Blender.app/Contents/MacOS/Blender` with or without option `--gpu-backend`\n\n", "Crash without warning when opening material properties panel.\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: AMD Radeon RX 540 Series, ATI Technologies Inc., OpenGL, 4.5.0 Core Profile Context 22.20.16.03.220829\n\nBroken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: 55485cb379f7\nBroken: version: 3.5.1, branch: blender-v3.5-release, commit date: 2023-04-24 18:11, hash: e1ccd9d4a1d3\nWorked: no newer version works.\n\nWe get a hard crash without warning when opening the material properties panel in the \"Layout\" workspace right after startup (i.e. with a clean \"General\" new file).

I checked the face count and it was just 150k faces which is not a lot at all. It's definitely a modifier problem because when I apply the subd modifier the lag goes away completely even when sliding twice the amount of edges around. I thought that was maybe a hardware issue so I opened task manager and while sliding edges with subd on I get like 4 fps with severe stuttering to top it off. All that while the cpu was at 10% usage and 5% gpu usage with memory barely touched (6gb used out of 64gb). I have nothing else running in the background like an ativirus or music app, I have the latest version of windows 10, latest gpu and chipset drivers, latest bios etc... I even have gpu subdivision enabled without autosmooth to make sure it actually works properly. I even run an sfc/scannow to check for other kinds of issues but nothing changed. Subd in edit mode however is not only slow when sliding edges and vertices but also in adding loop cuts or insetting faces. It is extremely frustrating so it would be great if you could fix this. I know edit mode was not made to handle massive polycounts but 150k is again not a whole lot and definitely comfortable to run on my PC.

And it's particularly problematic in UPBGE (a fork of the old BGE based on the latest Blender source) because a game engine must animate objects in realtime with relatively small number of samples per frame.\n\nUpon an examination from the developers of UPBGE, it is found that the problem is due to the fact that the current implementation of alpha hashed transparency uses the world coordinate instead of the object space, as it is often recommended (e.g. [2017 ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games](p4TYf5DDpbQ)).\n\nIt appears that a simple change from the world to object coordinate fixes the problem as shown in this [test commit (see line 80) ](e0a8638d0b255f2fc6ce778d10dd0d12a467b4d3#diff-2b8bf4f9e10009510d02c14e3659ee032c73f829de5453d6abcdf6a3f884fdfdR80), which produces the following result:\n[alpha-hashed-problem-solved.mp4](alpha-hashed-problem-solved.mp4)\n\nIt's my understanding that the [original author ]() decided to use the world matrix to avoid the difficulties with certain corner cases, like when the object is scaled by an extreme factor. However, while such a problem may be circumvented relatively easily (e.g. discard the scale information from the matrix) such a problem described above may pose more substantial issues with making an animation or rendering in realtime.\n\nSo, I hope this problem and the suggested fix may be evaluated again since we have more people interested in using Blender for such purposes now, thanks to the gaining popularity of EEVEE.", "Incorrect Fresnel layer weight shading on backfacing geometry\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: Radeon (TM) RX 470 Graphics ATI Technologies Inc. 4.5.13587 Core Profile Context 20.4.2 26.20.15029.27017\n\nBroken: version: 2.91.0 Alpha\n\nFresnel layer weight creates a sharp boundary instead of a smooth falloff when viewed on backfacing geometry.\nIn this example there are 2 hemispheres with the same material, but the left one has inverted face normals.\n\n\n[fresnel bug.blend](fresnel_bug.blend)\n", "\"New Image\" UI improvement\nNOTE: This design is still under discussion and is incomplete.\n\n# Current Issue\n\nThe UI for image creation in Blender doesn't make it very easy to pick an optimal resolution and could be improved for usability.\n\n\nExperienced Blender users might know that you can:\n- Drag over both fields to edit both at the same time\n- Type `*` or `/` to multiply or divide the resolutions to keep standard resolutions\n\n# Proposal\n\nWe need to make these options more obvious and readily available:\n- Add a dropdown for common resolutions (128,256,512,1024,2048,...)\n- Add a toggle to either keep image square.

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "VSE: Tool option Drag options exposed in Annotation & Sample Tool\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 462.59\n\nBroken: version: 3.0.0 Alpha\n\nDrag options shouldn't be exposed in the Annotation and Sample Tool, as it doesn't make sense to change dragging behaviour in these tools:\n\n\n", "Mesh selection in viewport broken with scenes using a high number of models\nOperating system: Windows-10-10.0.22621-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3080 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.02\n\nBroken: version: 3.5.0 Alpha\nWorked: Never (2.8+)\nWe are working on a commercial project with imported SketchUp scenes using 55K+ models and running more and more into broken scenes with selection issues in the viewport.\n\n`What we figured out so far:`\n- Selection in the outliner works\n- Some models can be selected by a point and click\n- Other models can't be selected by a point and click\n- Models at a different location will be selected by a point and click and not at the mouse pointer location\n- Box select is messed up and doesn't work overall (selects just parts of the model or fails completely)\n- Lasso select seems to work as intended\n- Circle select seems to work as intended (but can freeze Blender)\n- Some random models can cause a hard crash of Blender when selecting them by a point and click\n**When we delete all my other scenes in the Blender file and purge the data the selection modes work again.**\n\n\n\n\n[T104008_Selection_Bug_350_v006_CUBES_REPORT.blend](T104008_Selection_Bug_350_v006_CUBES_REPORT.blend)\n\nTry to select cubes.\n\n", "Add In Front/Visible option to lasso and box mask tools\nCurrently Box Mask and Lasso Mask create the mask through the object, which is not useful in some cases.

I'm not sure how common it is that middle-click gestures are enabled without having to manually configure it.\n\nAre there systems where using a middle-click still isn't practical?\n\nOptions could be:\n\n- Remove this preference.\n- Remove the keys that use Alt-LMB *(means re-working the keymap in some places)*.\n- Use an alternative shortcut that doesn't conflict, eg: OSKey (Cmd / Super / Windows-Key).\n\n *(By default this conflicts on Linux with many window-managers, these would need to be re-configured not to use Super-LMB).*\n\nUnless this is given some attention it's likely Alt-LMB will be used more, to the point Emulate-Middle-Mouse preference isn't useful and we'll need to remove or document all it's known limitations and accept Blender isn't fully usable with this

Run Blender\n2. Open `ellie_animation.blend`\n\nSomething else worth noting is that apparently a group of people on the Blender Artists forums are experiencing the same issue: 1342795\n\n`blender-stdout.txt` and `blender-stderr.txt` were generated like so:\n`C:\\Users\\Mustafa\\blender-4.0.0-alpha+main.66d20c8723e6-windows.amd64-release>blender --factory-startup --debug-all > blender-stdout.txt 2> blender-stderr.txt`\nI've even provided a file (`gdb-blender.txt`) containing the output of interactively debugging blender with the GNU Debuger, in case you'll need it.\nAll debug logs and related files were created on Windows.\n\nThanks in advance!

Anyone is free to pick up this task and contribute. For any questions or needed reviewers, please tag @JosephEagar and @JulienKaspar .\n\nThere are a number of operators in sculpt mode that affect hidden geometry. As a general rule this should be avoided.\n\n- [ ] `bpy.ops.sculpt.face_set_edit` to Grow/Shrink, Fair or Delete face sets needs to have the \"Modifiy Hidden\" property disabled by default and disabled in all menu and keymap entries.\n\nList of further operators:\n- [ ] `bpy.ops.sculpt.face_sets_init` \n- [ ] `bpy.ops.sculpt.face_sets_create(mode='SELECTION')`\n- [ ] `bpy.ops.mesh.paint_mask_extract()`\n- [ ] `bpy.ops.mesh.paint_mask_slice()`\n\n", "Mesh-based armature interaction (\"Mesh Gizmos\", \"Face Maps\")\n# Preface\n\nThe current way of interacting with bones in a production environment is based on Custom Shape Objects, which can disappear inside the mesh, be at a completely different place from the area they control, and in general require a fair bit of design from the rigger and learning from the animator to efficiently use.\n\nUsing the Python Gizmo API, I created a prototype of an alternative system, where we can click on geometry on the deformed mesh itself to select bones and control said mesh.\n\nThe goals of this task are:\n- Gather feedback from animators and riggers.\n- Finalize a design, to the extent that is possible within the limitations of a Python prototype.\n- Find developers who could implement this in core Blender.\n\n### The Prototype: \"Bone Gizmos\" add-on\n\n[Video: Setting up a single bone gizmo](attachment)\n[Video: The add-on in use](attachment)\n\n\nYou can [download the addon](bone_gizmos) as part of the Blender Studio Pipeline. You have to download the whole repository from the repo's home page, then extract the `bone_gizmos` folder into your addons folder.\n\n### Features\nA list of proposed features, partially working in the prototype, although there is plenty of space for UX discussions.\n\n- A gizmo's shape can be:\n - An entire object (in the bone's local space, with the already existing transform offset options applied)\n - A vertex group/face map/any attribute of an object (in world space).\n- Gizmo Colors:\n - There are three states to worry about: Unselected, selected, hovered.\n - Currently, user can specify two colors: Unselected and Selected. Hover-state is indicated by opacity ONLY. Having only one color, or three colors, is something to discuss.\n - The colors can be taken from the bone group's colors, if the bone has a group assigned, or set uniquely on a per-bone basis.\n - Colors should actually NOT be this customizable. Instead, users should be forced into a set of pre-defined colors, that can only be customized at the Theme level.\n- Gizmo Display:\n - A gizmo's visibility is based on the bone's visibility; From user POV, a bone and its gizmo should be a single entity.\n - If the selected object/vertex group cannot be used to construct any faces, draw the edges with line drawing instead.\n- Interaction:\n - Since it's just a prototype, it's currently left-click only, and doesn't account for mouse drag threshold, which is very bad for auto-keying. In the final implementation, it should behave the same way as bones do now, except:\n - Default transform mode: Translate/Rotate/Scale, including trackball rotation, rotating along view, and locking any transformation to 1 or 2 axes. These defaults are defined by the rigger on a per-bone basis, and can be bypassed by the animator with a button press, or in a nuclear fashion by disbaling them altogether as a user preference.\n - Snapping: It is possible, only through Python, to specify an operator name and parameters that should be executed when a gizmo is touched. This can be used for automatic IK/FK snapping. But it would need an interface similar to a Keymap entry, where we can pick an operator and feed it parameters.\n\n\n**Design Questions**:\nWhile making the prototype, I ran into some design questions where the answers aren't so simple:\n- Ways to minimize set-up time? Currently, each gizmo needs a vertex group. That's fine, but may need workflow operators to quickly switch from Pose Mode to Edit Mode on the relevant mesh.\n- How to avoid overlapping gizmos? I think there are cases where they might be necessary, and a system that allows the rigger to create bone layers that are mutually exclusive, would be a potential solution.\n- If there is more than one way to deform some geometry (eg.: Shape Key, Armature, Lattice), how to communicate which out of several potential controls was used to achieve the current shape?\n\nThere might be no perfect answer to all of these, but they are things to keep in mind and mitigate.\n\n### Prototype Limitations\nThese issues are listed just to clarify that these behaviours are known, and would most likely be easy to fix/avoid in the final implementation, but can't really be addressed in the prototype:\n\n- - [ ] Mouse hovering does not take depth into account. This was fixed! [#94794]\n- Visual depth culling stops working when gizmo is being hovered. [#94792]\n- Transparent lines appear between the triangles. [#94791]\n- Currently the mouse movement threshold user preference is not being taken into account, which is terrible when trying to use the system with auto-keying enabled.\n- Performance is poor; Grabbing the vertex positions from the evaluated mesh takes about 2ms per gizmo.\n- Interaction is always with left click and cannot be customized.\n- Gizmo can not be visible during interaction.\n- When the mesh is modified, user must press a Refresh button to synchronize the gizmos.\n- Renaming bones will leave a gizmo orphaned, don't do it! :D \n\nFeedback and discussion welcome!

Because the areas in the centimeters model are so big number-wise it doesn't find any match. So either I think the amount needs to be unlimited (I would put in 100 and that would probably have the same results as when the mesh is 100x smaller) or this needs to be addressed from the unit scale side of things.\n\nThis is in Meters (scaled the mesh 0.01), we get a good window selection because they are mostly the same:\n\nAnd in Centimeters nothing more than the one face is selected.\n\n\nMaybe the scale in Units should be used in these operators to make the mesh smaller?\n\n\nThanks for looking into this.", "Fullscreen doesn't activate if the 3d Viewport is maximized \nTested on :\n\n2.73 a\n\nGooseberry 2.73 # d92f591\n\nWhen the viewport is maximized ( Ctrl + Up Arrow).

The first problem occurred when I tried to open an HDRI File. I could load the HDRI file in a fresh new file as long as I loaded the image file in the devlook viewport mode into the world shader node. Switching to the rendered viewport setting afterwards worked. But as soon as I loaded the hdri file into the world shader node while having the viewport in rendered mode it didn't worked. I read that other users also had this Problem.\n\n2.) Another problem I ran into was, that material changes while displaying rendered viewport with eevee didn't effect the viewport. Also the material preview wasn't affected by the changes. Somehow the changes worked after using the undo command! As a workaround I did two changes in a material node f.e. changing the roughness twice, then doing one undo command and the first change was shown in the rendered viewport.\n\n3.) also had some problems that objects wouldn't show textures even with the proper uv unwrapping and mapping. Even on simple objects like a cube or a plane. However after some time fiddling around with the problem, magically after switching between editing and object mode at some point the textures appeared. I think there could be some kind of texture-display error concerning the edit mode.\n\nOtherwise great work! im really looking forward to the 2.8 stable release!\n\nGreetings from Germany,\n\nMoritz\n\nBased on the default startup file.", "Blender 2.8 / rel.

This is because there can be a large time difference between the recording of the two points; The first vertex stores a record of the pressure only at the moment the stylus first touches the tablet, subsequent changes of pressure before the stylus begins to move across the tablet are not recorded in the stroke. Only after the stylus starts moving is the second point recorded with the current pressure.\n\n**Proposed solution**\nAny time the stationary stylus tip is touching the tablet, the drawing routine polls the changing tablet pressure continuously. When the detected pressure is higher than the pressure of the last recorded point, the pressure of the last recorded point is overwritten by the newly detected (higher) pressure. This way, the pressure of the first and second points in a stroke is much more likely to be similar, the width of the start of the line will more closely match the artists intention, and the likelihood of artefacts is reduced.", "C and V keys pressed while drawing a Grease Pencil stroke unchangeable in keymaps\nOperating system: Windows 10\nGraphics card: RTX 3070\n\nBroken: 3.0.0\nWorked: n/a\n\nWhile in the middle of drawing a stroke, pressing C and V keys toggle guides on and off. \n\nThe C and V keys can be bound to something else in preferences, but whatever you bind them to, pressing them while in the middle of drawing a stroke still turns the Guides on and off.

However there are two distinct use cases which require different settings.\n\n* Meshes with autosmooth and/or custom normals.

If you use it on non-Basis shape key, in addition to the described behavior with remaining shape keys, the Basis shape key will always use the default settings (smoothness and fractal = 0).\n\n**Exact steps for others to reproduce the error / sort-of-transcript of the video**\nwatch?v=s9dPcdHOlpo\nIf you use the Subdivide Edge Ring, leave the default settings, and go through the shape keys, you can see that the positions of vertices are slightly off between the current/modified shapekey and others.\nHowever, that changes when you change interpolation to \"Linear\" - then they start being the same.\nWhen you go through various options it seems that the only thing applied properly across all shape keys is the number of cuts.\nAll shape keys other-than-the-active-one seem to always be using the \"Linear\" interpolation, and profile factor = \"0\"\nFrom my tests it doesn't matter which shape key you use this action on - it will always have the same effect between the current shape key and all other.\n\nNow, there's something even weirder goin on with the regular Subdivide.\nIf we Subdivide the mesh with default settings, it will look the same in all shape keys - that's great.\nHowever, if we change something, then the mesh across shapekeys will look different.\nAs a general rule, if we Subdivide a shapekey like Key 2, then the Basis will look like it was Subdivided with the default settings instead of the chosen ones (besides the number of cuts), but all other shape keys will also be modified, just in a different way than the active shapekey.\nFor example, if we change the smoothness of our Subdivide, then other shapekeys will look just \"less modified\". If we check the coordinates of the vertices, then we can see that in Key 1 they are transformed exactly half-way to their position in Key 2.\nHowever, if we use the Fractal setting, then the results are different: The Basis is still default-Subdivided, but the vertices of Key 1 are not just halfway there to the positions of Key 1 - they're completely different.\nOn a final note, with regular Subdivide, if, instead of Subdividing Key 2 you did that to the Basis, then both Key 1 and 2 would look like Key 1 in my example.

What I'm currently using to revert the child of' constraint the base formula that I use to find the offset is\n\n```\noffset = con.inverse_matrix.inverted() @ con.target.matrix_world.inverted()\n```\nTo calculate it also with the influence I use this formula to append and calculate each constraint offset\n```\noffset = Matrix.Identity(4) + con.influence * (parent_matrix @ con.inverse_matrix - Matrix.Identity(4))\n```\nThis works good for location, for rotation and scale I use lerp\n```\noffset_lerp = Matrix.Identity(4).lerp(parent_matrix @ con.inverse_matrix, con.influence)\n```\nand then **invert and multiply all the offsets** with the desired matrix.\n\nFor all the other tranformation constraints I found that I could find the difference between matrix world and matrix basis and then multiplying the inverted difference, but this requires to isolate each constraint, which can cause issues when drivers are applied.\n\n```\ndiff = basis.inverted() @ obj.matrix_parent_inverse.inverted() @ obj.parent.matrix_world.inverted() @ matrix_world \nobj.matrix_basis = obj.matrix_parent_inverse.inverted() @ obj.parent.matrix_world.inverted() @ matrix @ diff.inverted()\n```\n\n", "Python API: TRANSFORM_OT_resize unrecognized in bpy.ops.mesh.extrude_region_move (macros can change their operators during execution)\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce RTX 2070 Super/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.76\n\nBroken: version: 2.91.0\nWorked: (newest version of Blender that worked as expected): don't know\n\nError displayed in the system console: \"Converting py args to operator properties: : keyword \"TRANSFORM_OT_resize\" unrecognized\n\nIn a blank view \n- add a circle (with 'bpy.ops.mesh.primitive_circle_add(radius=1, enter_editmode=True, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))' in the Python console)\n- then extrude it toward the center by typing {key E}, then {key S} to create an annulus. \n- The command shown in the Info window is: \n\n```\nbpy.ops.mesh.extrude_region_move(MESH_OT_extrude_region={\"use_normal_flip\":False, \"use_dissolve_ortho_edges\":False, \"mirror\":False}, TRANSFORM_OT_resize={\"value\":(0.560534, 0.560534, 0.560534), ...etc\n```\n\nSo `TRANSFORM_OT_translate` (in a \"normal\" extrude_region), became `TRANSFORM_OT_resize` (by hitting {key S})\n\nThis same command pasted into the Python Console or in the text editor gives the error shown above.\n\n\n", "Snap Increment with \"Absolute Grid Snap\" not working correctly in XY plane\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: Radeon RX 580 Series ATI Technologies Inc. 4.5.0 Core Profile Context 23.Q3.230719\n\nBroken: version: 3.6.2\n\nDescription of error\nWhen moving an object by using Increment Snapping with \"Absolute Grid Snap\" enabled and constraining the plane the object no longer moves with the mouse cursor.

This will make possible to have brushes with 1px size (diameter) to paint single pixels.\n- Add alternative squared paint cursor display over cursor settings to have a better feedback.\n- Add AA toggle as a unified paint setting to make possible paint in pixel art with any brush and size.\n- Add pixel grid overlay in the overlays panel.\n\n**CONS:**\n- Cursor isn't aligned with pixel grid.\n- So much options user have to configure before doing pixel art.

When using touch, two fingers will scroll up and down. In Blender, two finger touch should work like an Apple touch pad or Apple magic mouse: two finger movement will orbit the view; holding down command zooms, holding down shift pans. Instead, it simply does nothing.\n\nBlender.app, default cube. Place two fingers down on a Wacom Intuos Pro tablet and move them around; it should orbit, but nothing happens. Well, the bottom status bar flickers back and forth as though command/shift or alt is pressed. \n\nThere are two reasons why this happens. \n1. Blender has incorrect Cocoa/AppKit code. I worked on AppKit for ~13 years at Apple. Below is a diff that addresses some of the issues. The code attempts to keep track of m_multiTouchScroll, but this isn't needed. It should key off of hasPreciseScrollingDeltas instead. I tested this diff with: Apple Magic Mouse, old school Apple scroll wheel mouse, Wacom tablet; all things work the same (except Wacom, which has the bug I'm reporting fixed). There is also a comment about intuos5, but that seems to be incorrect and outdated, but I don't have an Intuos 5 to test with.\n\n[0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch](0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch)\n\n2. Wacom's tablet touch drivers do link-checked behavior based on the bundle identifier \"org.blenderfoundation.blender\". In other words: they change the touch behavior when they see the target application is Blender. Wacom needs to fix this, but I'm not sure how to log a bug report for them.\n\nTo prove this, I created the sample application:\n\n[TabletTest.zip](TabletTest.zip)\n\nThe sample application has the blender bundle identifier set, as seen in this screen shot:\n\n\n\nIn ViewTest.m I log the flagsChanged:\n\n``` - (void)flagsChanged:(NSEvent *)event\n```\n{\n NSLog(@\"%@\", event);\n}\n```\n```\nIf you run the app and do a two finger scroll in the window you will see some flagsChanged logged, which is very strange because Shift/Alt/Cmd have not been pressed! Wacom is faking them for some reason, and changing the scrolling data, which messes up Blender.\n\nChange the applications's bundle identifier to \"org.blenderfoundationXX.blender\" (you can simply edit the info.plist) and run it again; it will then behave correctly.\n\n\n\nI don't know how to fix item 2 for Blender; I'm fixing it in my own build of Blender by changing the bundle identifier to org.blenderfoundation.bl3nder after it is built. I looked into identifying the events, and I can could identify the source as coming from the wacom driver but I can't fix them. \n\nI'm trying to find a contact at Wacom to have them fix this, but once it is fixed we still need item 1 fixed. \n\n\n\n", "Grease Pencil drawing sticks to Camera (when stroke placement is Surface and drawing outside of camera border)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12\n\nBroken: version: 3.0.0 Alpha\n\nGrease Pencil drawing sticks to Camera (when stroke placement is Surface and drawing outside of camera border)\n\n[#92351.blend](T92351.blend)\n- open .blend\n- start a stroke inside camera bounds and end it outside camera bounds\n- stroke will stick to the camera on the end\n\n\n", "Draw Face Set brush bug\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 950M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.40\n\nBroken: version: 3.0.0 Alpha\n\nDraw Face Set brush doesn't work properly and select faces randomly\n[DjHiCdF9fE.mp4](DjHiCdF9fE.mp4)", "Select Interior Faces is not working\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA RTX A4000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.24\n\nBroken: version: 4.0.0 Alpha\nWorked: \n\nthe operator \"select > select all by trait > interior faces\" is not working at all.
