It doesn't remember original layout.\n - Expected: It will restore original layout.\n\n-----------\n\nOriginal description:\n\nWhen rendering, the user's layout will not be recovered after some specific conditions are met:\n- The `preferences.view.render_display_type` is set to \"SCREEN\"\n- The Screen in the current window has been maximized in any way (by a previous render call, or if the user has manually maximized some area)\n- A render is called with the Screen already maximized\n- The area passed to the render call is invalid or doesn't match the maximized area in the window.\n\n\n1) Set Preferences > Interface > Temporary Editors > Render In to \"Maximized Area\"\n2) Maximize the Screen in some way (call a render or maximize any area manually)\n3) With the maximized screen, call a new render, making sure to prevent the render operator from receiving the maximized area as context, that is, prevent the cursor from being on top of the maximized area. This can be done in several ways:\n - Put the cursor outside the active Blender window and call a render with F12 (the area passed to render operator will be None)\n - Put the cursor in an empty area of the Topbar and call a render with F12 (the area passed to the render operator will be of type \"TOPBAR\")\n - Call the render from the Topbar menu > Render > Render Image (the area passed to the render operator will also be of type \"TOPBAR\")\n4) The Screen Layout conflict has been created. Now click \"Back to Previous\" button on top trying to recover the original Layout. This will fail and the user's layout will be now lost. This always happens when the render operator doesn't receive the maximized area in its context.\n\n**This is commonly unnoticed because**\n\n- The user tipically has the cursor on top of the maximized area\n- The user rarely calls a new render from the Render menu. Using F12 is much more common.\n- It's rare to call a render with the window being in focus but with the cursor outside of its bounds.\n\nBut when it happens it's a shame, because there's no explicit way for the user to restore the original layout, and saving the blend file will also save this new broken layout.\n\nThis bug report is related to: #86708\n\n", "Panel order is not saved when preferences window closes\nWindows 10, GTX 1660\n\nversion: 2.83 (sub 7), branch: master (modified), commit date: 2020-03-10 07:58, hash: 1aa7c4c28a06, type: \nbuild date: 2020-03-10, 08:52:15\n\nWithin the Preferences Editor, you can change the ordering of various sections but the changes are not retained when you close the Preferences Editor.", "Modifiers added in edit mode are undone out of order if you go back to object mode\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1070 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66\n\nBroken: version: 2.83 (sub 13)\nWorked: Never (2.8+)\n\nModifiers added in edit mode are undone out of order if you go back to object mode and then start undoing.\n\nAffects both old and new undo system.

IOW, at the end of the timeline it should show a frame with no man — however instead it shows a frame with the man.\n\nFrom my experimentation it seems that the problem is somehow related to cuts in the video. Because when there's no cuts or only a cut at the end, video is rendered properly.\n\n\nI haven't figured a way to do this from scratch on an irrelevant video, so I attached an archive with a tiktok video I'm editing and a `bug-report.blend` file which has all the necessary setup (most importantly, cuts, because they seem to trigger the problem).\n\n1.

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.", "\"Add [Object]\" menu not working correctly or lagging\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.40\n\nBroken: version: 3.6.0\n\nI found out that the context menu that appears just after adding an object tends to lag or bug if you have split screen the viewport and the compositor with the checkbox \"use nodes\".\n\n1.

But in the days/weeks prior it was 3.4)\n\nOn my MacBook M1 Max (with all upgrades possible), I have had to force quit Blender countless times in the last 48 hours after turning on viewport Cycles view. Upgrading to 3.5.1 has seemingly made it a constant problem. Even now opening a brand new project, then turning on Cycles render, it starts saying it’s loading kernels (very slowly), and never renders, freezing the viewport, forcing me to force quit. So it seems I no longer can turn on Cycles in 3.5.1.\n\nThere is no further steps really, this is happening on a new project for me. Hopefully you all can see this and figure out something! I’m happy to provide further details if you need anything. I use Blender for my day-to-day at work so fingers crossed this isn’t the new normal for the foreseeable future.

When the crash occurs, the active shader program has an active uniform block 'sssProfile'.\n\nFor the 'sssProfile' uniform block, GL_UNIFORM_BLOCK_BINDING is 0.\n\nFor uniform binding 0, GL_UNIFORM_BUFFER_BINDING is 0.\n\nTherefore, there is no uniform buffer bound to the 'sssProfile' uniform block. I suspect there is also no texture bound to the 'sssTexProfile' sampler either. I am assuming for this shader this uniform block is coming from lamps_lib.glsl, although an identical uniform block is also present in effect_subsurface_frag.glsl.\n\nI can prevent the crash by binding a dummy uniform buffer of the correct size to 'sssProfile'. In this case the rendering of the material in the preview appears corrupt.\n\nI tried adding an `#if !defined(USE_TRANSLUCENCY) || defined(VOLUMETRICS)` around the uniform block and corresponding sss_profile function in the glsl file, but the problem persists. I suspect that there is a case where this uniform block is actually being accessed without the uniform buffer being bound.\n\nMy check for missing uniform buffers also fires on 'clip_block' in other shaders.\n" ]

opacity value doesn't work with Blender 2.83+ (Intel HD 630 with Mesa 20, regression from D6729)\nOperating system: Mageia 8 x86_64 (Linux)\nGraphics card: Intel HD Graphics 630, Mesa 20.1.0\n\nBroken: 2.83.0, 2.90.0-aed11c673efe\nWorked: 2.82a, 2.83-ce76e17584ee\n\nIn Blender 2.82a, when using a reference image with opacity between 0.0 and 1.0, the image is properly blended using the opacity value, provided that \"Use Alpha\" is enabled. (I.e. an image with opacity 0.20 will be less visible than an image with opacity 0.80, though both are transparent - like in most image editors.)\nA few weeks back I used 2.83-ce76e17584ee, and there the \"Use Alpha\" setting was renamed to \"Transparency\", but the behavior stayed the same.\n\nOpacity working in Blender 2.82a:\n\n\nAfter updating to 2.83.0 (stable) now, I see that opacity no longer works as intended, it behaves like an on/off switch without any blending.\nAn image will look the same with opacity 0.0001 or 1.0 (and will be invisible with opacity 0).\n\nOpacity not working in Blender 2.83.0 (same .blend):\n\n\nCurrent 2.90 alpha seems to suffer from the same issue.\n\n- Add > Image > Reference\n- Pick an image\n- In object properties, enable Transparency, and try different values of Opacity. Opacity doesn't impact the blending of the reference image in the viewport (unless it's 0, which makes it disappear).", "Fully transparent generated images draw colors in image editor\nGenerated images follow the next alpha association:\n* Byte images use straight alpha\n* Float images use premultipled alpha\n\nIt is easy to create a fully transparent image with a non black color. Since Blender 2.91 we introduced drawing of pure emissive colors in the image editor these colors resulting in drawing the generated color perceptually without alpha. This could introduce confusion to our users. This report will collect these reports.\n\n\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.

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 `Color Ramp` node between the `Magic Texture` and the `World Output` nodes. Now you can see the `Magic Texture` in the viewport.\n\nAnother test:\n1. 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. Add a `Noise Texture` node and connect an output to the `Volume` socket on the `World Output` node.\n5. Notice that you can see the impact the `Noise Texture` is having on the scene, but you can't see the `Noise Texture`\n6. Place a `Color Ramp` between the `Noise Texture` and the `World Output` nodes. You still can't see the `Nosie Texture` in the scene.\n7. 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. Yet when you look at objects in the scene, the light reaching them is still affected by a volume shader you can't see.\n\nHere's a video demonstrating this:\n[Volumetrics not visibile in viewport in certain sitautions.mp4](Volumetrics_not_visibile_in_viewport_in_certain_sitautions.mp4)", "Eevee Light Limitation testcase T91611 crashes on Win11 Intel Arc GPU \nOperating system: Windows-10-10.0.22621-SP0 64 Bits\nGraphics card: Intel(R) Arc(TM) A770 Graphics Intel 4.5.0 - Build 31.0.101.4090\n(note: also tested on driver .4032 latest stable, which also crashes)\n[blender_system_info.txt](blender_system_info.txt)\n\nBroken: 3.3.2, 3.4.1\n\n \n\nWhile tracking down another bug (direct lights not appearing in Eevee), I found that the test case for #91611 hard crashes blender.\n\nAnalyzing the code, the crash happens because the GPU module cannot create a 3D texture with dimensions `4096x4096x576`.

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", "Blender crashes right after loading up a blend file or when creasing a specific mesh on a slightly older version of said blend file\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.77\nCPU: Ryzen 7 3700X\nRAM: 16GB, roughly 7GB available when loading\n\nBroken: version: 3.2.0\n\nFollowing a sculpting course i'm currently trying to crease the claws of a model in the attched blend file.\nBlender keeps crashing without further notice when doing so.

[ "Viewport fps tanks when application is full screened on macOS\nOperating system: macOS-13.4.1-arm64-arm-64bit 64 Bits\nGraphics card: Metal API Apple M1 1.2\n\nBroken: version: 3.5.1\n\nI've noticed that when using either my M1 Air or M1 16\" Pro, when running Blender, the viewport performance is heavily dependent on the physical size of the viewport on screen. At first I thought this was just a limitation of my base model M1 Air, but it also happens on my M1 Pro Mac when plugged into a 4K or 5K display. Having Blender fullscreen will drastically reduce the viewport performance, but scaling the window down will fix it. Setting the scaling in macOS lower can also reduce the issue.\n\nAs far as I can tell, this happens in both 3.5 and 3.6, Metal and OpenGL backend. \n\nPerhaps this is intended functionality, but I can run Blender on potato PCs and not have frame drops like this. Even just the default cube will drop tons of frames on both my Macs. \n\nOpen Blender on a high resolution display and just start using it. The viewport performance is usually pretty poor on 4K / 5K displays if not scaling the window down.\n\n", "Crashes when Switching to Material Viewport / Rendered Viewport / Rendering\nOperating system: Windows 10\nGraphics card: 2 Nvidia GTX 1660 Super's\n\n[blender_system_info.txt](blender_system_info.txt)\n\nBroken: blender 2.8 / 3.4\n\n\nBlender runs completely fine when editing and building a model but once rendering is involved, even in preview, it immediately closes with no explanation.

[ "Advancing Displace and Solidify modifiers to handle overlaps\nI briefly discussed this with C. Barton. 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). Then the simplest method would angle the normals away from each other. However, this does all require the ability to examine adjacency, and I'm relatively inexperienced in blender internals, having only contributed minor bits to sculpting tools and physics code.

I sculpt the mesh in the Solid or Wireframe (I don't sculpt in Wireframe at all, but this problem occurs in that mode as well) viewport and then undo the changes, but the undo does not update the model in the Material Preview or Rendered viewports.\n\nWhy I sculpt this way and why this error (or by design) is problematic and annoying:\n- I can see the topology much better in Solid shading with matcaps. However, I also want to be able to see how the sculpt looks under more finalized lighting settings in real-time while I edit and experiment with different sculpting or placement of facial features, for example.\n- I am constantly undoing brush strokes in a sort of error-correction method of sculpting. Naturally, reducing undoing strokes would be more efficient overall, but not being able to see the reverted mesh from undoing strokes absolutely debillitates confidence of an artist when they're suddenly not working on the most updated model.\n- This can cause bad sculpting errors as one looks from one viewport to the other to \"sanity check\" or simply check progress and be fooled into thinking that the models are synced, when they're actually desynced. The artist might not notice this and continue sculpting, which will update both views again, but it can cause unintentional sculpting errors.\n\nI'm not sure if this was a conscious design choice (2.82 also has this problem. I did not test pre-2.79 versions), but if it was, it makes absolutely no sense why there is even the possibility of anything desyncing between viewports, no matter how the artist works.

Each one of these data as a different solution for this:\n\n- Coordinates are being applied to the base mesh from the grids manually by using the Apply Base operator. When modifying the base mesh, that changes the subdivision limit surface, updating the result as coordinates in grids are stored as displacement in the ##CD_MDISP## datalayer. This is not the standard design of a Multires sculpting software, but this approach works for all the expected use cases and it allows for some non-standard functionality (like sculpting the base mesh while previewing the displacement or sculpting in deformed meshes).\n- Element visibility is stored in the ##ME_HIDE## flag in ##MVerts->flag## for meshes and in a bitmap which is part of ##CD_MDISP## for grids. As far as I know, there is nothing that keeps this data in sync. \n- The Sculpt Mask is stored in the CD_PAINT_MASK for vertices and in the CD_GRID_PAINT_MASK for grids. The main sync point is in ##BKE_sculpt_mask_layers_ensure## were the current state of ##CD_PAINT_MASK## is copied into a new ##CD_GRID_PAINT_MASK## datalayer when grid mask data does not exist, and it is never updated again. When applying Multires with ##CD_GRID_PAINT_MASK##, the mask data is also not copied to the new base mesh. \n- Face Sets are stored in ##CD_SCULPT_FACE_SETS## for base mesh polys and Multires reads them directly based on the index of the face the grid is. This makes them to be always in sync, but they are not editable per element in Multires. \n\n\nThis is affecting future development in the following ways:\n\n- As the paint mask is not synced from grids to the base mesh, there is not possible to implement features like mask extract from Multires as there is no ##CD_PAINT_MASK## datalayer in the base mesh after applying the modifier to extract the new mesh. \n- The Sculpt Vertex Colors Multires implementation includes a ##CD_GRID_PROP_COLOR## datalayer and uses a similar approach as masks. If we replicate the same code to sync it with ##CD_PROP_COLOR##, were are going to have the same issues, but for this feature those are not acceptable. Vertex Colors should be always in sync between the base mesh and grids without requiring anything from the user. Also, there can be multiple ##CD_PROP_COLOR## datalayers, which is a feature that does not exist in the sculpt mask datalayer. \n- If we want to implement sculpt layers for displacement, that will require to add another datalayer to store them. I'm still not sure how they will be stored (coordinates, displacement relative to the layer 0...). Implementing this feature on top of the current design means dealing with the base mesh sync issue for multiple layers plus always running the Multires smooth propagation for all of them each time the base layer changes.\n- There are also some features that are trivial to implement (like PBR vertex painting using a datalayer that contains color + PBR values at the same time) that are also limited by not having mesh/multires data unified. \n\n\nThe mesh/grids datalayer management project should try to provide a common solution to all these problems. Ideally, it should be possible to use the same vertex datalayer transparently from the tools and the Multires code, having all these abstracted by another system that keeps the mesh and grids data always in sync.\n", "Multires: Editing base mesh creates random results on higher subdiv levels\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.67\n\nBroken: version: 2.90.1\n\nI applied a multiresolution modifier on this mesh, and it adds geometry that I didn't sculpt on the mesh (bumps, cracks...).

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", "Support dragging to change tabs in the side-bar\nNote, this was reported as a bug however it's a TODO (wasn't supported in 2.7x).\n\n----\n\n\nOperating system: Windows-10-10.0.17763 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.39\n\n\nBroken: version: 2.80 (sub 60)\nWorked: (version before the click transparent passthrought)\n\n\nCannot drag on the tabs to select other tab like normal tab behavior on Blender.\n\n- Factory defaults\n- Press 'N' on the 3D View.\n- Try to drag on the tabs on the \"WM_OT_context\", the result is the box selection.\n\nSee attached gif (ignore the mouse cursor offset, that is due to 4k display with only 125% scale applied.)\n\n\n\n\n", "Selecting vertices and centering the model crashes Blender\nOperating system: Windows 10\nGraphics card: RTX 2070 \n\nBroken: 03015a9b222e\n\n\nSelecting some vertices and trying to center the selection crashes blender.

First, the expected result: when using mouse, rotation of 360 gives a result of 360). Then, the result caused by the bug: when writing the angle by using the keyboard, 360 gives a result of approximately 0.\n\n\n[Default scene - 2.8.blend](Default_scene_-_2.8.blend)\n\n[Default scene - 2.79.blend](Default_scene_-_2.79.blend)\n\n" ]

Since autokeying doesn't insert a keyframe as the value changes, that's probably why the slider is unresponsive. \n\n**Solution**: Perhaps we should separate (despgraph-wise) NLA strip animated property evaluation from when we evaluate the NLA system for general animation? Animated strip properties would only be evaluated and flushed on frame change or when the whole frame needs refreshed. Then normal non-NLA animation evaluation will just read the strip properties as is. This would allow the slider be responsive. It also allows the user to change these properties and view their changes without having to keyframe, just like any other Blender animated property. \n\n**Potential Problems with Solution:** What do we do when strip influence is animated and the user changes it (without keying) then inserts keys on character bones.

It's a source of confusion. \n\n**Solution:** [Originally proposed by angavrilov]]. We treat extrapolation `Hold_Forward` as bounded on the left and infinite on the right.*FModifiers note:*It's important to note that the Action Track does not evaluate the same as normal strips which is [[https:*developer.blender.org/T66946#723602 |intentional](https:*developer.blender.org/T66946#724251). FModifiers will affect the track's boundaries so keyframes don't necessarily define the Action Track's evaluation bounds. So adding a default cyclic modifier to channels effectively makes the Action Track's evaluation bounds infinite. Even extrapolation `None` in this case appears to not work properly. This behavior is still intentional even though it appears broken. The user-side solution is to restrict the modifier's frame range.

This can cause a lot of confusion and uncertainty during production. Proper deletion of datablocks requires that they are first un-linked, then they can be purged via File->Clean Up->Recursive Unused Datablocks. This works beautifully, and I would like to propose adding an option to have this operation executed after existing deletion operators. For example, after deleting a collection of objects, it would then also delete everything that was used only by those objects, such as their mesh and shape key datablocks, materials, actions, textures, etc.\n\nMy previous proposal was to have an option to execute Recursive Purge only on file save, which seemed to make sense to everyone I talked to at the time. (@dr.sybren @mont29 @JulianEisel @SimonThommes ) \nI still think that solution would be a step forward, but the new proposal above would achieve the same goals in an even more foolproof way. \n\n### Use case\nCurrently, this can very easily happen:\n- Animator duplicates an overridden character. All its objects get a .001 suffix.\n- Animator deletes that copy, saves their file, and later re-opens it. Only one \"layer\" of unused objects has been cleaned, so there can still be orphan object datablocks lying around unseen.\n- Animator duplicates the character again. Now the number suffix of their objects are all over the place. Some of them have .001 and others have .002.\n\nAs they continue working and duplicating characters, the old, unused objects slowly get deleted, and the name suffixes really get all over the place. It's not nice to get your objects names all mixed up like this, as things get really confusing when trying to troubleshoot problems in a production file, since everywhere where one object references another, the mismatching suffixes give the troubleshooter anxiety and uncertainty. The only way to avoid this currently is to tell the entire production team to always run a recursive Purge after deleting anything, which is very error-prone. \n\n\n### Potential issues\n\n- ~~The current recursive purge purges Text datablocks, which is bad because they don't have the possibility of a \"Fake User\", so they should be excluded (or better yet, be included in the \"fake user\" system, and get a fake user by default). ~~ (Fixed by [D10983](D10983))\n- Actions don't have fake user enabled by default. The long standing issue of Action datablocks \"disappearing\" on users and making them lose hours of work if they forget to click Fake User would be exacerbated by this change. This could be trivially fixed by giving Actions a fake user on creation, and forcing users to clean up their unused Actions themselves.", "Blender development todo list -- Tools (migrated from wiki)\nNOTE: this is a direct dump of Tools (without cherrypicking the valid items)\n\n\n# Scene\n\n**New scene - Full Copy**\nSeveral things are still not copied or reassigned when using this tool:\n- [ ] Particles - Not even the particle systems themselves, not to mention re-assigning 'objects' pointers to copied IDs too, see #40891.\n- [ ] Textures when they are only used by e.g. modifiers (i.e. not by a material, world or lamp).\n- [ ] Textures used by modifiers are not re-assigned to new copies when possible either (only objects are handled).\n\n# Library System\n- [x] Hard (or even impossible) to relocate libraries that have been moved (#44958).

(#24534)\n- [ ] DOF node gives no realistic results as users expect, documentation needs upgrade for it.\n- [ ] Defocus node is very slow when large blur radius is needed, could be optimized somehow (mipmap, summed area table?) (#29481)\n- [ ] Defocus node does not work nicely without a camera controlling the blur radius. This makes external compositing workflows with defocus difficult. At the heart of this is a design conflict, because defocus is not a true postprocessing effect #36745\n- [ ] Fast Gauss (Gabor filter, Young/VanVliet) has bad results for edge cases.

This leads to confusion when nodes apparently don't work, because nothing prevents linking such variable values into constant inputs. Compositor nodes should keep track of constant values and limited inputs on the node level (also in node groups!).\n- [ ] Compositor gives unexpected results with specific curve mapping due to precision loss, see #36621\n- [ ] \"Full Sample\" merging does not work with the File Output node, sample merging happens only for render result outside compositor. Real-time editing might also be improved to deal with samples better (#36811, #39143)\n- [ ] Accumulation method in the Lens Distortion node causes artifacts on noisy input #37462\n- [ ] Compositor does not support render slots #43260\n- [ ] Scaling down produces artifacts due to lack of ellipse filtering of sampler #51070\n\n**Image formats**\n- [ ] Upgrade our DPX code to read newer or different versions, copy the ImageMagick code?

Try unchecking CPU hoping to force blender to actually use the GPU and have tax manager up to see if gpu is even being used\n5. blender crashes without rendering, no sign of gpu being used on task manager but CPU usage spikes to 100%\n\n**What I've tried so far that might be helpful**\n\n- tried clean reinstalling different versions of blender, both newer/experimental and older/more stable builds\n- made sure I reset BIOS in case this is a new component/migration error\n- made sure the settings for blender in NVIDIA control panel were all compatible or high performance \n- made sure NVIDIA drivers are all studio version and up to date\n- made sure blender cache folder didn't have any kernel errors\n- installed any updates to windows, this did make the gpu visible in OptiX but unfortuantely the same issue persists even with OptiX on any version where blender just won't use it and uses only cpu (despite being unchecked)\n- double checking how much memory I have on my new gpu vs the old one - yup it does\n- benchmarked my gpu using port royal and making sure I could render a project in Premiere. GPU did fine on the benchmark test and was able to render a 20min video fine. Only blender seems to be the problem\n- noticed today in stackexchange there are a lot more reports with others having the same issue, even with equivalent AMD gpus, and all comments said this seems to be a bug\n\n", "Rendering instability from Blender 3.5 to 36+\nOperating system: macOS 13.4.1\nGraphics card: Apple/AMD W6800X Duo\n\nBroken: 3.6 to 4.0\nWorked: 3.5.1\n\nI get substantial instability when rendering animation sequences in Blender 3.6 and above, compared to 3.5.

Today I left Blender 3.5 rendering and have outputted all 250 frames without a single issue using the GPU.\n\nBut previously in 3.6 I get a variety of frames – sometimes 30 or 40, sometime just a single frame – before I have to reboot Blender and start the rendering process again. I've tried all sorts of tricks, like using tiling to render and even switching to CPU-only, but in all cases, the animation process will eventually crash Blender.

My Mac Pro is a standard system with 64GB RAM and no strange or non-Apple additions – it should be rock solid.\n\nI don't have one specific scene to give you, but I've experienced all manner of instability since 3.6 came out – there is obviously a core difference in the app from 3.5 to 3.6+.

It takes several brush strokes to push hair into a different direction and align it. Curves tend to drift away from the brush, especially close to the tips.\n\nA good combing brush should feel almost like a real, physical hair comb. It should \"grip\" the hair without letting it drift out of the brush region, while allowing slippage in the hair direction.\n\n# Current problems\nGoal positions for vertices are correctly computed by the brush and initially applied. But then segment length and collision constraints get solved, which moves points away from initial positions. Large brush strokes in particular cause large corrections for length constraints, which diminishes the brush effect.\n\n\nEspecially points at the tip tend get corrected so much that the initial displacement of the comb brush is quickly lost. That is because the length constraint works from the root upwards and only moves the end point of each segment. This \"follow the leader\" solution has the advantage that it only requires one iteration for a perfect length constraint, but the downside is that it artificially overcorrects curve tips. This issue has been described in section 3.1 of \"Fast Simulation of Inextensible Hair and Fur.\" (Müller et al.).\nFTLHairFur.pdf\nRecently a correction factor was introduced (#104589) to make curve tips more responsive, but only partially solves the problem.\n\n# What is the desired behavior?\nCombing should feel like a physical comb. Hairs between the teeth of a comb are constrained in their lateral movement, but can move (with some friction) along the direction of the hair.\n<img src=attachment width=\"300\">\n\nThis suggests that, rather than just an initial point offset, combing should be implemented as a constraint itself. This gives greater control over the priority and weighting of brush influence relative to other constraints. The solver can then try to satisfy segment lengths, collisions, and brush constraints at the same time, rather than overriding brush goals immediately.\n\n# Irrelevant aspects of real combs\nReal physical combs are open to one side to make inserting hair easier. If that side faces down the hair will fall out. This is not a feature we need to replicate. Instead the hair should generally be restrained laterally, but move freely in the longitudinal direction.\n\nReal combs also only work if held at a right angle to the hair direction. Brushes in Blender don’t usually have an orientation, so we can assume that this is always the case.\nCombs are also generally planar, while Blender brushes are spheres or cylinders (depending on projection mode). We don’t need all hair constraints to lie in the same plane.\n\nReal hair has some friction when dragged through a comb. This is a useful feature because it extends the influence of the brush beyond the immediate brush position. But we can simplify the brush and assume a moderate constant amount of friction with a simple tool setting (or disable friction altogether).\n\n# Formulating a comb brush constraint\nAll existing curve editing features can be understood as a simplified position-based constraint system. The goal now is to define an *objective function* that describes a suitable \"comb constraint\" and improve the curve constraint solver so that it supports this new constraint in addition to existing length and collision constraints.\n\nAn formulation of such a constraint can be found in section 5.1 *Keyhole Constraint* of \"A robust and efficient Lagrangian Constraint Toolkit for the Simulation of 1D Structures\" by Adrien Theetten.\nTheetten-2009-JCAD.pdf\n\nThe constraint minimizes the distance to a goal point. The goal is found at the beginning of the stroke by looking on each curve for the closest point to the brush center. The key difference to a simple \"grab\" constraint is that the point parameter `u` along the curve is also a variable, meaning that the point can slide along the curve to minimize deformation, as long as the deformed curve still goes through the goal point.\n\nIt must be noted that the curve has to be differentiable for this to work properly. A simple cubic spline interpolation helps generate a smooth gradient to move the keyhole point in the right direction along the spline.\n\n# Test implementation\nA test implementation shows the improved behavior of the constraint-based brush: The curves are following the brush much more strictly and it only takes a single stroke to align curves.\n\n\nCode: 105769\n\nA few further improvements should be considered for a full feature:\n* The constraint solver should be generalized to support additional constraints in the future.\n* Length constraints should apply to both sides of a segment equally instead of the follow-the-leader approach (solving from the root up). This will require more iterations but make it more compatible with other constraints. Zero weights for root points ensure pinning to the surface.\n* Some simplified stiffness constraints for segment angles can help avoid the \"floppiness\" of curves.\n* Better collision handling is needed. Collision constraints should not attempt to solve length constraints simultaneously, since that only works for the last-solved segment and makes the solution very non-linear.\n* The comb constraint is solved with a linear projection. A few iterations of gradient descent or a similar method for just this constraint type might improve convergence.\n* Currently `segment_length` and similar constraint constants are recomputed at the start of each brush stroke. This is susceptible to drift over multiple brush strokes, as any residual error of the solver is carried over into the next stroke. While improving convergence of the solver alleviates this issue it shouldn't be expected to get a totally accurate solution every time. `segment_length` and other (supposed) constants should be persistent as attributes and only change when e.g. grow/shrink brushes modify them.", "Blender crashes with Noise Texture Node + Hair Particle System + Eevee\nOperating system: Darwin-19.6.0-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon RX 480 OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.10.18\n\nBroken: 8dc95f61f3\nBroken: version: 2.92.0\nBroken: version: 2.91.2\nWorked: version: 2.83.12\n\nBlender 2.92 with AMD crashes with **Noise Texture Node**and **Hair Particle System** with render engine Eevee.\nWith Blender 2.91.2 with AMD it doesn't crash but colors are incorrect.\n\nWith 8dc95f61f3 with Intel GPU, there's no crash but colors are incorrect in the same way as in AMD - 2.91.2.\n\n1.

I'm not sure what else might cause a crash when Blender is already open.\n\nBy adding extra logging to a custom build of Blender, I've determined that the crash when starting Blender occurs when calling the `open` (`WTOpenA`) function: GHOST_Wintab.cc#L85\n\nMy drawing tablet's software also reports an exception in `WTOpen`, the value of which appears to equal 0xC0000005 which I think indicates a `STATUS_ACCESS_VIOLATION` according to 596a1078-e883-4972-9bbc-49e60bebca55.\n\n\nIn the drawing tablet's software, this exception only occurs if I actually connect the tablet to my PC, whereas Blender crashes even when the tablet is not connected.\n\nCurrently, if I don't actually need my tablet, I'm working around the issue by starting Blender headless, changing the Tablet API setting to Windows Ink, and then starting Blender normally.\n\nI have already tried updating the drivers for my tablet to the newest version and it made no difference.\n\nIf I start Blender with `--debug-wintab`, all that's printed is:\n```\nPS D:\\Downloads\\temp\\blender-4.0.0-alpha+main.dd9a92785acc-windows.amd64-release> .\\blender.exe --debug-wintab\nRead prefs: \"C:\\Users\\Thomas\\AppData\\Roaming\\Blender Foundation\\Blender\\4.0\\config\\userpref.blend\"\nLoading Wintab for window 00000000000910C4\nPS D:\\Downloads\\temp\\blender-4.0.0-alpha+main.dd9a92785acc-windows.amd64-release>\n```\n\nEvery version of Blender I've tried between 2.79 and 4.0.0a crashes unless I have the Tablet API set to `Windows Ink`.\n\nI don't know the specifics of how Wintab is handled, but could it be possible to either catch the exception in `WTOpen` and allow Blender to continue loading, or to check for a connected tablet before attempting to call `WTOpen`, similar to what my tablet's software appears to be doing?\n\nUnfortunately, Wintab getting into this erroneous state where it crashes in `WTOpen` occurs too rarely for me to figure out how to reproduce it and I'm not even sure if it's Blender that is causing it to get into this state in the first place.\n\n", "Regression: Unable to move camera/area light with gizmo (intel GPU)\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: Intel(R) UHD Graphics Intel 4.5.0 - Build 30.0.101.1122\n\nBroken: version: 3.2.0, 3.3\nWorked: 3.1\nCaused by 5045968f24\n\ni cant move my camera using move tool or tranform tool on left side bar\n\n- select camera\n- Choose move or transform tool\n- Move camera with gizmo (won't be able to move)\n\n[bug camera.blend](bug_camera.blend)\n[blender 3.2.mkv](blender_3.2.mkv)", "When \"Pie Menu on Drag\" is enabled in user prefs, Ctrl + Z has a tendency to open the shading menu by accident\nversion: 2.80 (sub 74), branch: master, commit date: 2019-07-05 21:52\nbuild date: 2019-07-06, 01:03:01\nplatform: Linux\n\nThis may be more of a design issue than a bug, but it's happened to me about 100 times now and it's quite irritating.\n\n**To reproduce:**\n\n - enable User Preferences > Keymap > Preferences > Pie Menu on Drag.\n - open a complex scene (one where the undo operator will have a significant lag) \n - fill the undo history with events, as though you've been working for a while\n - Press Ctrl + Z a couple times while moving the mouse a bit, rolling your hand so that Ctrl is released just before Z (in the manner of a busy artist)\n\nIf the user happens to release Ctrl earlier than Z while moving the mouse, this can bring up the shading menu, interrupting the user's workflow. This may sound like an edge case, but when working quickly, it's actually really frequent and annoying! It seems to especially effect large scenes where there is a lag in the effect of the undo operator.\n\nIdeally, the \"Pie On Drag\" feature should not listen for key presses if those key presses were part of a different combination that has yet to be completely released.

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.", "Sculpt: Grid overlay for Grab active point do not work.\nOperating system: Windows-8.1-6.3.9600-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.47\n\nThis seems to be issue only with Nvidia GPUs on windows.\n\nBroken: version: 3.0.0 Alpha\n\n\nGrid overlay for Grab active point do not work.\n[2021-07-18_18-56-46.mp4](2021-07-18_18-56-46.mp4)\n\n\n**Steps to reproduce**\n[#89942.blend](T89942.blend)\n\n- Open file\n- Check if wireframe overlay is drawn under cursor\n\nWhat fixes this is to have any transform gizmo visible while using brush, then it works until Blender is restarted.\n\n\nFrom #92703:\n\n> This was proposed on the blenderartists thread, I have no idea if it works or if it could broke the preview on the AMD cards\n>  \n> If you know how to compile you can fix it by erasing ! from the line 1157 : if (!depth_test) {\n> to read like so: if (depth_test) {\n\n\n", "API: Drawing artifact when drawing inside Gizmo and blend mode is enabled\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.96\n\nBroken: version: 3.2.0 Release Candidate\n\nDrawing artifact when drawing inside Gizmo.draw and blend mode is enabled.\nLook at the line across each graphic/rectangle.\n\n\n[GizmoDrawingIssueBlendAlpha.blend](GizmoDrawingIssueBlendAlpha.blend)\n1.

This is bad design and should not go into the release if possible. Instead the limitations that don't allow us to return `AssetHandle`objects directly to BPY should be resolved. I think this can just be done by allocating the `AssetHandle` and letting the `FileDirEntry` own this. Then we can return the handle safely to BPY. There may be some pitfalls involved with that though." ]

[ "Blender 2.83 crashing and lagging when rendering the viewport (cycles).\nOperating system: Arch Linux\nGraphics card: GTX 1050 ti\nDriver: nvidia-lts-1:440.82-19\n\nBroken: Blender 2.83 LTS (Tesded with and same issue with blender from blender.org website, Snap package and from the Arch Community Repository)\nWorked: There was no problems in 2.82a\nSuspected culprit: d712f1f83a\n\n**Description of the error**\nThe render view (the viewport typically when working with shaders) causes the interface to get extremely lag and sometimes totally stuck when rendering the viewport. Didn't find any issue rendering 250 frames of animation, but most of the times I'm working with the nodes shades setup and I change some nodes making the viewport start rendering, using cycles, it gets stuck for something like 10 seconds and then it can crash or just continue.\n\nBut I haven't been able to use blender for more than 5 minutes without a crash with this problem and lagging even when I simply change the view position on the viewport. I have tested many other files and they all have this same problem. Also happened when using CPU rendering instead of GPU. \n\nI tried using the option debug-all but I don't think there is any hint there at all. \n\n\n```\nShader name: default_empty\nNumber of SVM nodes: 3\nPeak stack usage: 0\nTime (in seconds):\nFinalize: 0.000000\n Surface: 0.000002\n Bump: 0.000000\n Volume: 0.000001\n Displacement: 0.000001\nGenerate: 0.000004\nTotal: 0.000005\nI0605 16:02:45.568426 1404890 svm.cpp:66] Compilation summary:\nShader name: shader\nNumber of SVM nodes: 5\nPeak stack usage: 0\nTime (in seconds):\nFinalize: 0.000000\n Surface: 0.000004\n Bump: 0.000000\n Volume: 0.000000\n Displacement: 0.000001\nGenerate: 0.000005\nTotal: 0.000005\nI0605 16:02:45.568414 1404906 svm.cpp:66] Compilation summary:\nShader name: shader\nNumber of SVM nodes: 5\nPeak stack usage: 0\nTime (in seconds):\nFinalize: 0.000001\n Surface: 0.000003\n Bump: 0.000000\n Volume: 0.000002\n Displacement: 0.000001\nGenerate: 0.000006\nTotal: 0.000007\nI0605 16:02:45.568498 1404889 constant_fold.cpp:46] Folding Base Height::Value to constant (0.2).\nI0605 16:02:45.568521 1404889 constant_fold.cpp:46] Folding Cone Height::Value to constant (1.4).\nI0605 16:02:45.568538 1404889 constant_fold.cpp:46] Folding Radius::Value to constant (0.45).\nI0605 16:02:45.568555 1404889 constant_fold.cpp:46] Folding SideLengh::Value to constant (0.9).\nI0605 16:02:45.568574 1404889 constant_fold.cpp:46] Folding punchin::Value to constant (-2.15).\nI0605 16:02:45.568588 1404889 constant_fold.cpp:46] Folding Margin::Value to constant (3.8).\nI0605 16:02:45.568603 1404889 constant_fold.cpp:46] Folding NoiseNoise::Value to constant (-0.495).\nI0605 16:02:45.568615 1404889 constant_fold.cpp:46] Folding stripe::Value to constant (-0.04).\nI0605 16:02:45.568629 1404889 constant_fold.cpp:46] Folding midlevel::Value to constant (0.08).\nI0605 16:02:45.568642 1404889 constant_fold.cpp:46] Folding Displacement.001::Value to constant (1).\nI0605 16:02:45.568656 1404889 constant_fold.cpp:46] Folding DirtStrenght::Value to constant (2.7).\nI0605 16:02:45.568673 1404889 constant_fold.cpp:58] Folding Combine XYZ.001::Vector to constant (0.45, 0.45, 0).\nI0605 16:02:45.568691 1404889 constant_fold.cpp:58] Folding Combine XYZ.001::Vector to constant (0.45, 0.45, 0).\nI0605 16:02:45.568706 1404889 constant_fold.cpp:46] Folding Math.001::Value to constant (-0.9).\nI0605 16:02:45.568719 1404889 constant_fold.cpp:46] Folding Math.004::Value to constant (4.7).\nI0605 16:02:45.568735 1404889 constant_fold.cpp:58] Folding Vector Math.005::Vector to constant (0.2475, 0.2475, 0.2475).\nI0605 16:02:45.568754 1404889 constant_fold.cpp:58] Folding Combine XYZ::Vector to constant (-0.9, -0.9, 0).\nI0605 16:02:45.568773 1404889 constant_fold.cpp:46] Folding Math.001::Value to constant (-4.7).\nI0605 16:02:45.568795 1404889 constant_fold.cpp:58] Folding Vector Math.005::Vector to constant (-0.45, -0.45, 0).\nI0605 16:02:45.568812 1404889 constant_fold.cpp:58] Folding Combine XYZ::Vector to constant (-4.7, -4.7, 0).\nI0605 16:02:45.568837 1404889 constant_fold.cpp:58] Folding Vector Math.005::Vector to constant (-4.25, -4.25, 0).\nI0605 16:02:45.568871 1404889 constant_fold.cpp:113] Folding Math.002::Value to socket convert_color_to_float::value_float.\nI0605 16:02:45.568920 1404889 constant_fold.cpp:113] Folding Mix Shader.001::Closure to socket Mix Shader::Closure.\nI0605 16:02:45.569067 1404889 graph.cpp:675] Deduplicated 9 nodes.\nI0605 16:02:45.570071 1404889 svm.cpp:66] Compilation summary:\nShader name: cone\nNumber of SVM nodes: 4000\nPeak stack usage: 61\nTime (in seconds):\nFinalize: 0.000878\n Surface: 0.000478\n Bump: 0.000175\n Volume: 0.000035\n Displacement: 0.000051\nGenerate: 0.000739\nTotal: 0.001618\nI0605 16:02:45.570232 1404906 device_cuda_impl.cpp:819] Buffer allocate: __svm_nodes, 64,640 bytes.

This seems to be independend of the unit system (metric/imperial).\n\nIf this is a known limitation then the shown precision of the unit scale slider should reflect that. Also a fix for the clipping plane issue is needed as that did work in 2.80.\n\nBased on default startup.\n1. In Scene Settings: enable seperate units\n2. set unitscale of 0.00009 or less (metric r imperial)\n3. observe what the dimensions sliders tell you about the dimension of the default cube.\n4. observe the buggy floor grid in the viewport probably due to the same bug in the clipping sliders (wasn't there in 2.80)\n", "GPencil: Texture Image Alpha pass through grease pencil strokes\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.87\n\nBroken: version: 2.83.1\n\nContext: Using texture image to make some kind of 2d fur on top of a GPencil Object\n\nThe Image Texture used to make some fur is mostly transparent and the brush used to make the colored part is a texture paint brush with Cloud Mask (it was made entirely in Blender with Blender tools).\n\nWhen on top of the GPencil object, the part of the Image Texture that is only half transparent(between 99%-1% transparent), makes the GPencil color disappear, even when moving the center point behind the one of the fur images.\n\nOn the contrary, when on top of another Image Texture (imported to be used as camera mapping), the Image Texture of the fur doesn't impact the transparency of that one.\nNotice that the Image texture boundary, even from the imported one, has problems with clipping and always makes a white line appear.\n\n- Open attached .blend file\n- Zoom in and out to notice the alpha transparency influencing the GP object\n\nThanks for your help!\n\n\n\n\n\n\n\n[bug_alpha.blend](bug_alpha.blend)", "Edge Sliding with subdivision surface is extremely laggy (caused by \"bad\" UVs and UV Smoothing in the modifier)\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.56\n\nBroken: version: 3.4.0\n\nSo I've been modelling a raptor the last week and I noticed that viewport performance in edit mode was extremely laggy with subdivision surface modifier enabled. 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 had not turned on the GPU Subdivision preference or made any other preference changes before encountering the problem.\n\nI reasoned this is not a duplicate issue of the one I saw from the windows user because the behaviour they saw was different (not a silent crash).", "Crash on linux with amd gpu with two subdivision modifiers\nOperating system: Linux Mint 20.3, core 5.13.0.40 and 5.4.0.109\nGraphics card: AMD Ryzen 5 5500U\n\nTested on 3.1.2, 3.1.1\n\nSame file works on Windows 11 with NVIDIA RTX 2060 and worked on Linux with Intel integrated GPU (linux pc is sold, can't test it anymore)\n\n\n\n> Add to mesh first \"subdivision surface\" modifier.

[ "When \"Pie Menu on Drag\" is enabled in user prefs, Ctrl + Z has a tendency to open the shading menu by accident\nversion: 2.80 (sub 74), branch: master, commit date: 2019-07-05 21:52\nbuild date: 2019-07-06, 01:03:01\nplatform: Linux\n\nThis may be more of a design issue than a bug, but it's happened to me about 100 times now and it's quite irritating.\n\n**To reproduce:**\n\n - enable User Preferences > Keymap > Preferences > Pie Menu on Drag.\n - open a complex scene (one where the undo operator will have a significant lag) \n - fill the undo history with events, as though you've been working for a while\n - Press Ctrl + Z a couple times while moving the mouse a bit, rolling your hand so that Ctrl is released just before Z (in the manner of a busy artist)\n\nIf the user happens to release Ctrl earlier than Z while moving the mouse, this can bring up the shading menu, interrupting the user's workflow. This may sound like an edge case, but when working quickly, it's actually really frequent and annoying! It seems to especially effect large scenes where there is a lag in the effect of the undo operator.\n\nIdeally, the \"Pie On Drag\" feature should not listen for key presses if those key presses were part of a different combination that has yet to be completely released. What do you think?", "GPencil: Undo System\n## Overall design\n\nThe gpencil undo system is a relative differential undo system (see Undo). Steps do not encode the whole object data, but rather only what changed between steps. We make use of the update cache (#95401) to retrieve what changed. \n\n## How undoing works\n\nWe only save “one-way” diffs. That means we can get from the current state into the future, but we cannot go into the past. E.g. when drawing a stroke and then deleting a layer, the system will save the change with the stroke and then the change with the layer. When we undo now we need to restore the deleted layer, but the previous step just has the data with the change of the stroke.\nIn this case we need to go back further in time until we find a step that changed what we want to restore. Then we need to re-apply all the diffs (going back to the future) until we reach the desired step.\nIn order to guarantee that we always find a step that has enough data in it, we force the first step of the “grease pencil undo chain” to be a full copy (initial full-copy). When a step is freed, we also ensure that the full copy is kept in the first position.\nIn the case that the previous step already encodes the element we are looking for, we just apply those changes to the current state.\n\n## How redoing works\nRedoing is more trivial: we just need to apply the step's diff onto the current grease pencil data.\n\n## Limitations\n\n~~**Going into object mode in an undo step**\nRight now, when going into any gpencil mode from object mode and then undoing will not work. This is probably because the global undo system is not able to restore the object mode for gpencil objects.~~\n\n**Undoing changes outside of the active grease pencil data**\nThe gpencil undo system only encodes a step if:\n - the active gpencil data was modified\n - the scene's frame changed\n - the step before was not part of the same undo system (initial full-copy)\nAll other modifications are not taken into account, and therefore not undo-able (similarly to how the mesh undo system works).\n\n**Editing multiple gpencil objects**\nBecause of how steps are encoded, the current system only supports undo/redo on the active GP object. If the dopesheet displays keyframes of several objects, only the modifications applied on the active object's one will be undo-able.\n\n\n## How to free the update cache\n\nWithout the undo system, the update cache was always freed after the update-on-write happened, e.g. after the changes were written to the eval object. With the undo system, we need to make sure that the cache is still populated when we encode a step. This can fail for example when we run a modal operator. Every modal execution might trigger an update-on-write, but only after the operator has finished do we encode the undo step.\nSo we need to make sure that we only free the cache after the encode step was run. This is done by tagging the gpencil data with a flag `GP_DATA_UPDATE_CACHE_DISPOSABLE` after the encode, and clearing it after a free.\n\n## Memory usage\n\nSteps that encode full copies or layer copies might become very large. In the worst case, the entire object might be duplicated multiple times in memory. This applies mostly to operations that modify layers (e.g. reordering layers, deleting a layer or adding a new one). \n\nAdditionally, we need to make a decision on what happens when the update cache is not populated. Right now, this will fall back to a full-copy of the data block. Again this will increase the memory usage substantially. An alternative would be to only encode steps when the cache is populated. Ideally this would be the case once the cache is used everywhere in grease pencil. \n\n## Implementation\n\nUndo system patch: [D13996](D13996)\n\nCo-authored-by: @yann-lty", "The Tool Settings UI should update when holding modifier keys\nIn Sculpt Mode, users can hold Ctrl to invert the effect of the current tool.

(see attached video examples)", "Recursive Purge Orphans datablocks on file save\nFully deleting datablocks from a blend file doesn't happen as easily as most users might expect, since \"delete\" is often used in the UI when \"un-link\" is what is actually meant. This can cause a lot of confusion and uncertainty during production. Proper deletion of datablocks requires that they are first un-linked, then they can be purged via File->Clean Up->Recursive Unused Datablocks. This works beautifully, and I would like to propose adding an option to have this operation executed after existing deletion operators. For example, after deleting a collection of objects, it would then also delete everything that was used only by those objects, such as their mesh and shape key datablocks, materials, actions, textures, etc.\n\nMy previous proposal was to have an option to execute Recursive Purge only on file save, which seemed to make sense to everyone I talked to at the time. (@dr.sybren @mont29 @JulianEisel @SimonThommes ) \nI still think that solution would be a step forward, but the new proposal above would achieve the same goals in an even more foolproof way. \n\n### Use case\nCurrently, this can very easily happen:\n- Animator duplicates an overridden character. All its objects get a .001 suffix.\n- Animator deletes that copy, saves their file, and later re-opens it. Only one \"layer\" of unused objects has been cleaned, so there can still be orphan object datablocks lying around unseen.\n- Animator duplicates the character again. Now the number suffix of their objects are all over the place. Some of them have .001 and others have .002.\n\nAs they continue working and duplicating characters, the old, unused objects slowly get deleted, and the name suffixes really get all over the place. It's not nice to get your objects names all mixed up like this, as things get really confusing when trying to troubleshoot problems in a production file, since everywhere where one object references another, the mismatching suffixes give the troubleshooter anxiety and uncertainty. The only way to avoid this currently is to tell the entire production team to always run a recursive Purge after deleting anything, which is very error-prone. \n\n\n### Potential issues\n\n- ~~The current recursive purge purges Text datablocks, which is bad because they don't have the possibility of a \"Fake User\", so they should be excluded (or better yet, be included in the \"fake user\" system, and get a fake user by default). ~~ (Fixed by [D10983](D10983))\n- Actions don't have fake user enabled by default. The long standing issue of Action datablocks \"disappearing\" on users and making them lose hours of work if they forget to click Fake User would be exacerbated by this change. This could be trivially fixed by giving Actions a fake user on creation, and forcing users to clean up their unused Actions themselves.", "Operators to add to the Outliner\nCurrently the Outliner allows users to fully manage Collections.

If you try that in Blender 2.77a, this will not happen.", "Paint Mode: Masking Modes\nThis is an important task related to the implementation of Paint Mode and #96225.\n\n# Painting Modes & Selections\n\nIn the current painting modes there are various ways of masking. Including all of these in their current form in a single Paint Mode would lead to a muddled and confusing design.\nBut still, these ways of masking should be supported:\n\n- Masking per vertex (Like Sculpt Mode masking)\n- Masking per face (To achieve sharp edges on face corner color attributes and image textures)\n- Masking based on selection (Synched with edit mode)\n- Masking based on a texture (Stencil Mask)\n\n# Issue\n\nThese ways of masking are very different and currently implemented as completely separate features.\nMoving all of these with their current design to a new Paint Mode would lead to multiple masks and selections having to be enabled and managed at the same time, each with their own overlay.\nThis issue can already be observed in the current Texture Paint Mode when enabling any of the selection masking modes and stencil masking at the same time.\n\nThe ideal way moving forward in Paint Mode has to be by combining these masking methods into a single cohesive design without regression in functionality.\n\n# Proposal\n\n### Masking Modes\n\nThe proposal is to add three easily accessible “Masking modes” to choose which data is being used for the masking operations in Paint Mode.\nThese should be easy to switch between via the number keys. \nThis directly parallels the selection modes in edit mode, grease pencil and the UV editor. And just like in these other modes they should be interchangeably usable for intuitive and fast masking.\n\n\n\nThe 3 modes would let you:\n\n- **Mask Vertices** (Vertex float)\nSame behaviour as sculpt mode.\n\n- **Mask Faces** (Face bool)\nWill restrict the masking to only fill in entire faces as completely masked or unmasked. This is far more useful than trying to paint face float values, which will almost always result in a stepping effect.\n\n- **Mask Pixels** (Greyscale image texture))\nThis feature should replace the current “Stencil Mask”.\n\n### Converting Masks\n\nThese masking features are meant for loose and temporary masks, similar to selections in other modes. \nFor more permanent masking for material and texture mixing it would still be preferred to paint image textures and use them as masks in the material.\n\nWith that use case in mind, it would be easiest to implement to convert the mask to another domain and data type every time the masking mode is changed (Similar to selection modes in Edit Mode).\n\nAlternatively we could test a way of abstracting/propagating the selection between those modes but that could just end up as far more complicated, less predictable and for questionable advantages.\n\n### Edit Mode Syncing\n\nAn important task that is tied to this is to convert the mask of Paint Mode to the Edit Mode selection (and vise versa).\nThis way masks can be much more precisely created in Edit Mode.\nWhile switching between Edit Mode should not be required - masking in Paint Mode should be intuitive enough for most cases - some workflows rely on this for painting precise attributes and technical textures.\n\nSo keeping this functionality will be a priority!\n\n(There are even other potential advantages from considering a Paint Mode mask an Edit Mode selection, like assigning materials directly in Paint Mode. \nThe design of #97903 could help in making this more clear.\n\n# Sculpt Mode\n\nIf these masking modes should be included in Sculpt Mode as well is questionable. \nMasking faces and based on an image texture is no use if you are only able to affect vertices with all tools available.\nThe only advantage would be to avoid mask conversion on mode switching (Which shouldn't be a problem) and to allow painting face corner color attributes with the Sculpt Mode painting toolset (Which is not what Sculpt Mode is for. For sharper edges you should increase the amount of geometry or use the bigger Toolset of Paint Mode).", "Weird edge lines in 3D Viewport (Edit Mode - Orthographic View)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.68\n\nBroken: version: 2.93.3\n\nIn Edit Mode when switching to Orthographic mode the edges sometimes look very thin, jaggy, disappearing in some place, dotted line style or just barely visible.

They are not related to geometry, and not related to illumination, since even the light AO regions appear noisy. Disabling adaptive sampling or changing the threshold to extremely small values removes the issue. Values for the noise threshold look inadequate in these regions. Setting it to 0.01 gives around 27 out of possible 256 light difference between adjacent pixels in HSL color. In regions with reduced noise, the level looks similar to what it should be, you can see both on the image below. The noise disappears when threshold is turned off, so it's not related to maximum samples count. Same issue does not appear on baking direct or indirect light and the noise level seems adequate. It's not related to denoiser, since it's not working in baked maps (unfortunately).\n\nIt's hard to imagine synthetic scene in which the situation will repeat itself. In the attached scene, you just need to click the bake button and see the results. Try changing the Noise Threshold values or disabling it.

[ "When \"Pie Menu on Drag\" is enabled in user prefs, Ctrl + Z has a tendency to open the shading menu by accident\nversion: 2.80 (sub 74), branch: master, commit date: 2019-07-05 21:52\nbuild date: 2019-07-06, 01:03:01\nplatform: Linux\n\nThis may be more of a design issue than a bug, but it's happened to me about 100 times now and it's quite irritating.\n\n**To reproduce:**\n\n - enable User Preferences > Keymap > Preferences > Pie Menu on Drag.\n - open a complex scene (one where the undo operator will have a significant lag) \n - fill the undo history with events, as though you've been working for a while\n - Press Ctrl + Z a couple times while moving the mouse a bit, rolling your hand so that Ctrl is released just before Z (in the manner of a busy artist)\n\nIf the user happens to release Ctrl earlier than Z while moving the mouse, this can bring up the shading menu, interrupting the user's workflow. This may sound like an edge case, but when working quickly, it's actually really frequent and annoying! It seems to especially effect large scenes where there is a lag in the effect of the undo operator.\n\nIdeally, the \"Pie On Drag\" feature should not listen for key presses if those key presses were part of a different combination that has yet to be completely released. What do you think?", "Blender ignores xinput mouse sensitivity (as a result, mouse cursor randomly jumps when I attempt to navigate, move objects, etc.)\nLinux, Debian Sid, GTX 680\n\nThis is what happens: if mouse sensitivity is default, everything works fine. If mouse sensitivity is, for example, 0.9 instead of 1, and I try to rotate view by holding middle mouse button, when I release it, mouse cursor jumps to position it would reach with default sensitivity. Automatic cursor wrapping in Blender also ignores xinput sensitivity, so if it happens, mouse cursor will jump unexpectedly even before I release mouse button. The same thing happens when I try to rotate or move objects. When sensitivity is set to low value, for example, 0.3, mouse cursor jumps to edge of the screen almost every time I release mouse button or move/rotate some object with mouse. And because of this, mouse does not wrap around from one edge of the screen to another seemlessly, it just starts behaving crazy, like rotating view at extreme speed.\n\nI have very sensitive mouse, and I cannot change its hardware sensitivity. So I have to adjust it with xinput, otherwise cursor will be \"flying\" too fast. This used to work with Blender in older distros where it was possible to adjust \"Device Accel Constant Deceleration\" to change mouse sensitivity. However, this seems to be not possible for a while now because this xinput property was removed. Instead, to change mouse sensitivity I have to adjust Coordinate Transformation Matrix. This works everywhere except in Blender. In case somebody does not know this, in Linux I have to use xinput to adjust sensitivity, because as far as I know there is no other way to do it (for example, in KDE systemsettings I can adjust only acceleration, and even if I set it below 1x, even to minimum 0.1x, it does not do much, and this is expected, since acceleration and sensitivity are completely different settings).\n\nSet mouse sensitivity to anything but 1. For example:\n\nid=\"pointer:Mouseemu virtual mouse\"; speed=0.3; xinput set-prop $id \"Coordinate Transformation Matrix\" $speed, 0, 0, 0, $speed, 0, 0, 0, 1\n\nOf course, you need to replace pointer name (text after \"pointer:\" prefix) with your own (if you do not know it, see output from \"xinput list\"). Then try to rotate view with middle button. You will see cursor to jump unexpectedly when you release mouse button or if you hit edge of the screen.\n\nAs far as I can tell, it feels like Blender always assumes default \"Coordinate Transformation Matrix\", and ignores real one. And as a result, Blender does not calculate mouse position correctly. This pretty much makes Blender practically unusable with mouse which needs xinput sensitivity adjustment. So far I was not able to found any workaround, and it is very hard to work with default sensitivity in my case.

Here: ", "Apply scale normal flipping\nThe apply transforms operator in blender can apply negative scaling to an object.\nHowever there is two ways to do this. If you scale your model with a negative\nvalue in editmode, you get flipped normals. This is because the vertex order in the\nfaces is preserved and that is what determines the normal. In object mode however,\nthere is a flag in the render engines to flip the normals back, if they are flipped due\nto negative scale. This inconsistency creates the problem with the apply transforms\noperator. The following image shows on top the behavior in editmode and at the\nbottom the behavior in object mode.\n\n\n\nOf course both behaviors have their reasoning to exist.\n\nOne reason for the rendering flag to exist is, that instances of the same object can\nbe mirrored without causing normal problems. Obviously there is no other solution\nto that, since the underlying mesh is the same for all instances, so the render engine\nhas to handle negative scales.\n\nOn the other hand, in editmode you don't want to change the loop order for all your faces\nif you are just scaling. It makes much more sense for editmode scaling to just change\nvertex coordinates. That means you need to fix the normals manually.\n\n\nThe apply operator can only be called in object mode. From object mode the current\nbehaviour looks as if it was flipping the normals. Actually it is just applying the\ntransform \"in editmode\", which looses the negative scale information for rendering.\nThis looks like a bug to some users and is confusing for new users. Users have actually\nrequested this to be changed:\n\n4Zdbbc/\n\nI also heard this request on the BCON22.\n\nHowever the question arises, do we add another option or do we just always flip the\nnormals to make it consistent with rendering? Another question is what happens to\naddons which are using this operator if the operator gets changed in this way?\nHow many addons are actually using apply scale on negatively scaled objects?\nDo those addons fix the normals by flipping them manually?\n\nThere is already a patch available to add this normal flipping without an option:\n\nD16382", "Object drop snapping should be disabled for cameras, lamps, etc\nE.g. when dragging a camera from the Outliner into the 3D View, it gets an all-0 rotation, which isn't useful. And it will always snap to an underlying surface, which is annoying because you wouldn't want a camera to snap to geometry or the grid. Think we should just bring back the old dropping behavior, even if it's a bit hard to predict which distance along the view it will use to place the object.\n\nIt wasn't intentional to have this. In review I asked to address this which I thought it was. Probably a misunderstanding.\n\nShould it be disabled for empties as well? It may be useful to have snapping for these.", "VSE: Operators missing cache invalidation\nOperating system: Windows-10-10.0.19042-SP0 64 Bits\nGraphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 462.59\n\nBroken: version: 3.1.0 Alpha\n\n\nThese things were also reported in: #90415 but not fixed yet.

Only the BSDF evaluation components multiplied with the light contribution differ [ eg. instead: L*glossy + L*diffuse -> L*diffuse if glossy is deactivated].\n \nThe example shows a scene with one big rectangular light at the ceiling, where glossy rays are disabled on. \nAs you can see, the BSDF image is darker compared to MIS, and the NEE version is a little bit brighter.\n\n\nThe MIS image is more or less a blended version of BSDF and NEE.\nBecause both BSDF and NEE do not converge to the same result, the MIS one is inconsistent/biased.\nSince the blending factors/mis weights depend on the sampling strategies, the result changes when using path guiding or the light tree.\nThis makes these optimized strategies unpredictable and can confuse the artists.\nIn the worst case, they report bugs on for the light tree and path guiding.\n\nA WIP fix is proposed in [D16965](D16965)\n\nBased on the default startup or an attached .blend file (as simple as possible).", "Blender development todo list -- Render\nNOTE: this is a direct dump of Render (without cherrypicking the valid items)\n\n### Render & UI\n\n- [ ] While rendering, manipulating images (like reload, resizing generated) can still crash Blender.

I have described what my problem is [here ]]. I do not necessarily want to simulate clicking but it turns out that I cannot update the contents of 'Viewer Node' image block. Finally, I thought the best way would be to automatically have backdrop enabled. So I followed the instructions given [[ https:*blender.stackexchange.com/questions/72742/depth-data-works-but-not-in-background-mode | here ](https:*blender.stackexchange.com/questions/102790/how-to-trigger-lmb-click-events-to-activate-a-specific-view-node-and-update-cont) by *Sebastian Koch* thinking that I should be able to dynamically add/remove view nodes and update the contents of the image block automatically. Although I could access to the pixels, but But this does not happen!\nI wrote the right code to do exactly what I show in [this video ]] but the pixels in \"Viewer Node\" image block do not get updated, as they do in the video. Not only that, I tried activating newly-added Viewer nodes manually (as described [[ https:*blender.stackexchange.com/questions/102790/how-to-trigger-lmb-click-events-to-activate-a-specific-view-node-and-update-cont | here ](https:*youtu.be/YCv5qdKLkZo)) but I am still unsuccessful in updating the pixels in the image block. I also tried removing the image block in Python and then continue adding new Viewer nodes. But from the time I remove the image block its contents will always be zero even if I redo the rendering.\n\nThe only way I could successfully update the contents of the image block was after, first, I followed *Sebastian Koch*'s solution and then wrote some code to remove/add all nodes and their links to get either depth map or surface Normals and did the rendering again. But the whole point of me trying to store pixels into Numpy arrays was to avoid doing re-rendering to get around the IO overhead. I could have instead stored two files (for both depth map and Normal maps) throught two Output nodes with rendering only once.\n\nFirst, if this behavior does not look like a bug, I would appreciate the community provide me an easy solution to do what I want. Second, It would be great if you can improve Blender's Python API and add ways of easily accessing rendering results in memory so that people like me who want to do millions of rendering do not need to deal with the delays cause by IO to transfer rendering results from memory to hard drive and can easily store the results into Numpy arrays and store them on disk in chunks. \n\n", "Scrollbar of Clip Editor's Graph and Dopesheet View does not update\nOperating system: elementaryOS 0.4.1\nGraphics card: GTX 1080\n\nBroken: 2.80, 58bfe93db614\n\nWorked: apparently never...\n\nIf you change the endframe of your scene, the scrollbar in the Clip Editor's Graph and Dopesheet view does not reflect the changes.\n\nOpen startup .blend\nGo to Motion Tracking Layout.\nSet Endframe to 1000.\nNotice how the scrollbar down in the Graph View of the Clip Editor does not change its length.\nNow try the same with any other Animation Editor, for example in Animation workspace\nIf you set the endframe to anything that makes the scene longer, the scrollbar will update accordingly and become shorter, indicating that you do not see the full range of your scene.", "Undo/Redo shortcut still active in the Blender File View window\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 452.06\n\nBroken: version: 2.91.0 Beta\n\nUndo/Redo shortcut still active in the Blender File View window\n\n* Open Blender with the default cube.\n* Move the cube a few times.\n* Open the “Preferences” window in the menu “Edit | Preferences...”\n* Then do Ctrl + Z to undo.

It does not happened with Eevee + OpenGL nor Cycles.\n\nI would guess maybe some bug in the Metal implementation and/or Metal shaders?\n\n\nWell, I used blenderGIS to import a DEM (digital elevation map : a point cloud) + some trinagulation which yield a mesh.\nThen I used blenderGIS to import 2 terrain textures (one covering 1:1 the mesh, one way smaller).\n\nWhichever of the 2 textures I import 1st, it will always be the 2nd that has its UVmap seemingly ignored.\nNote : I checked the UV map content in the UVmap editor.\nNote 2 : I use QGIS since 2019, I made sure that the CRS (projection) are the same for all 3 datas (DEM + geotiff textures).\n\n***Based on the default startup or an attached .blend file (as simple as possible).***\n\n***My best guess***\n\nA bug in the Blender's Mac implementation of Eeveee Metal (and or /shaders) ?\n\nPlease note that my 2 textures have different coverage of the mesh, and so the UV map reflects that.

The first image shows a cube with a color attribute added. The geometry nodes setup adds a red color to the \"Color\" attribute. This all works as expected as can be seen in the viewport and the spreadsheet. \n\n\n\nIf a GN cube is added instead of the standard mesh cube (which has been bypassed by the switch node) then the color attribute is added as expected. This can be seen in the spreadsheet as to be the same as the previous screenshot for the color attribute. However, it is not being displayed in the viewport.\n\n\n\nThis is a problem seen with any procedural geometry made with just nodes. As a workaround, you can have a single vertex as the only \"real\" geometry and use a join node to join with any nodal procedural geometry. Strangely though, this has to be the first connection in the join node, and won't work if it is second. This can be seen by the next 2 images:\n\n\n\n\n\nA similar related case is that some mesh nodes will also make the viewport lose the displayed attribute. For instance, if you create a cube, add a GN modifier and add a dual mesh node to the chain, the color attribute is still there, but no longer displayed in the viewport. This happens with some nodes (like mesh to volume and back to mesh) but not others (like subdivide or extrude).\n\n\n\nThere is also a related issue that when exporting to obj or gltf the color attributes are not exported if they are not displayed in the viewport. If apply the GN modfier, you have to actually click on the color attribute in the properties panel to see it in the viewport or to be able to export it. \n\nOddly, the fbx exporter seems fine without applying the modifier. It also doesn't matter if the color attribute is on the vertices, or face corners, or if the color is float or byte color. The same issues happen regardless.\n\n", "Objects with \"In Front\" don't appear when overlays are reenabled until viewport update\nOperating system: Linux-5.10.0-6-amd64-x86_64-with-glibc2.31 64 Bits (Debian testing)\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.73.01\n\nBut works on:\nOperating system: Linux-5.10.0-6-amd64-x86_64-with-glibc2.31 64 Bits (Debian testing)\nGraphics card: Mesa Intel(R) UHD Graphics 620 (WHL GT2) Intel 4.6 (Core Profile) Mesa 20.3.4\n\nBroken: version: 3.0.0 Alpha\nWorked: 2.91.2\n\nMight be the same as #102199 (Regression: Armatures [in front] overlay doesn't update properly (toggling overlay ON and OFF)) (which was bisected down to 0f95f51361)\n\nWhen an object (specific ones) is set to be displayed in front of everything else, it will not come back immediately when reenabling the overlays.

Cycles appears to force some sort of rounded/inverted cylinder normal at some point after the BSDF, leading to shading artifacts.\n\n\n\n\nNote the line down the middle of the strand/curves on the Cycles version. This is usually at the point where the (default) normal is facing fully away from the light source.\n\nThis happens on both the legacy particle system as well as the newer Curve based hair. It happens on both Rounded Ribbons and 3D Curve primitives.\n\n**Longer version**\n\nI want to render stylized fur. The approach I use is to copy the normals from the underlying mesh to the particle system or hair curves, and disable shadows. This makes a very smooth, toon-like shader.\n\n\n\n\nThis is based off of my old addon, encode-normals but normals passed as attributes from geometry nodes have the same issue, as do normals set right in the material itself, so it's not an issue with my addon or node tree.\n\nIn the example blender file, I have two planes facing upward. One has a legacy particle system and the other has a new hair curve. Both sets of strands/curves have a material where the normal is forced to be (0, 0, 1), or straight up, to show the base case. \n\nIn Eevee I get the toony flat shading, where each strand is basically a solid color. \n\nIn Cycles, I end up with part of the strand in shadow, and if you look closely the emulated rounded normals appear to be an \"inside out\" cylinder, so the line tends to show up where the light direction and normal of the fake \"cylinder\" are perpendicular (i.e., where light is grazing the outermost part of the cylinder)\n\nI can't turn this rounded normal off or override it. It's coming from something outside the BSDF. This completely breaks my stylized shader in Cycles and is an unintuitive behavior. Normals can be overriden on a material in any other situation/primitive that comes to mind.\n\nSteps I've tried:\n1. Setting normals from encoded vertex colors (addon)\n2. Setting normals from geometry nodes\n3. Setting normals outright in the shader (this example)\n4. Disabling shadow ray visibility\n5. Making the strand material transparent to shadows in shader\n\nOpen provided .blend and check both curve systems for rendering differences between Eevee and Cycles. \n\n[TestParticles1.blend](TestParticles1.blend)", "Regression: Strange crease when using proportional editing with the \"connected only\" option turned on (edge selected)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.72\n\nBroken: version: 2.93.0\n\nPretty sure this is caused by 21b9231d7f\n\nWhen using proportional editing, there is a strange pinching/creasing that is going on where it should be smooth.

Particles can get trapped inside solid objects.\n - B: Proposed behaviour: force direction is consistent across face boundary, but still reverses at midpoint.

This should be the basis for discussions on the implementation.\n\n# Goal\n\nFor an intuitive painting workflow it's necessary to have an eraser accessible at all times.\nThis has been a shortcoming in Blender for painting, since the erasing of alpha channels has only been available as a blending mode for brushes.\nThis is very hard to access via the UI and shortcuts.\n\n# Recommendations\n\nThe ideal solution is to have a very simple brush tool in the toolbar. Aside from the typical texture, stroke, falloff and cursor settings, it can only erase alpha.\n\nThis tool can then have the shortcut `E` assigned by default to make it very accessible.\n\n## Pure Emissive Colors\n\nThe motivation behind not offering a blending mode to \"Add Alpha\" in the Erase Tool is because this has been notoriously difficult to do like the user would expect.\nSee #86868 & #83342.\n\nWhen painting float or pre-multiplied images, the alpha is treated differently. Any color with an alpha 0 would have the RGB colors displayed as pure emissive colors and still visible.\nThe only way to erase the colors completely is to also erase the RGB channels to 0.\n\nAs a result the design for the brush should emphasise this: **The Erase brush is a destructive tool!**\nIf you erase the alpha directly via painting tools you should expect to likely lose the full RGBA color information.\nThe alpha 0 areas can be painted over with a new color afterwards. \n\nFor non destructive erasing of alpha values it is recommended to use a separate image as a mask. This can be done right now via nodes.\nThis non-destructive approach might not be very accessible right now but that can be addressed separately (Especially with the [layered textures design]())\n\n## Erasing Selections\n\nWe need to discuss how we want to handle other erasing operations like via Gesture Tools (Box/Lasso/Line Erase), or for example the Color Filter for gradual erasing. These generally affect the unmasked/selected areas.\nThere are different ways to enable this workflow.\n\n**Erase Operator**\n\nThe simplest way would be to add an operator to the menus and mapped to a shortcut (Like `Delete`) to erase the colors on any selected areas.\nThe user would in that case use the existing Gesture Tools and brushes to mask/select areas to define the areas to be deleted.\nThis approach would follow the Select -> Operate paradigm of Blender closest.\n\n**Erase Tools**\n\nThe existing Color Filter tool could receive an additional Filter Type to 'Erase'. This would allow gradual erasing in the case where it is needed.\nAdding Gesture Tools specifically or erasing is also possible but might just bloat the Toolbar.\n\n## Erase Mode\n\nAn alternative approach is to make the \"Erase Alpha\" blending mode in the regular painting tools more accessible.\nIn other painting application such as Krita every tools and brush has an \"Erase Mode\" button that can be easily toggled with a shortcut and applies globally to all tools and brushes.\nWe could implement this design as an alternative to the Erase Tools/Brush for users that prefer this workflow.\n\nIn that case the Erase Alpha blending mode would be a button in the header that can be toggled directly, instead of being part of the blending modes popup.\nA shortcut could also be assigned.\nThis toggle should be available for for all brushes and tools that affect colors.

Including all of these in their current form in a single Paint Mode would lead to a muddled and confusing design.\nBut still, these ways of masking should be supported:\n\n- Masking per vertex (Like Sculpt Mode masking)\n- Masking per face (To achieve sharp edges on face corner color attributes and image textures)\n- Masking based on selection (Synched with edit mode)\n- Masking based on a texture (Stencil Mask)\n\n# Issue\n\nThese ways of masking are very different and currently implemented as completely separate features.\nMoving all of these with their current design to a new Paint Mode would lead to multiple masks and selections having to be enabled and managed at the same time, each with their own overlay.\nThis issue can already be observed in the current Texture Paint Mode when enabling any of the selection masking modes and stencil masking at the same time.\n\nThe ideal way moving forward in Paint Mode has to be by combining these masking methods into a single cohesive design without regression in functionality.\n\n# Proposal\n\n### Masking Modes\n\nThe proposal is to add three easily accessible “Masking modes” to choose which data is being used for the masking operations in Paint Mode.\nThese should be easy to switch between via the number keys. \nThis directly parallels the selection modes in edit mode, grease pencil and the UV editor. And just like in these other modes they should be interchangeably usable for intuitive and fast masking.\n\n\n\nThe 3 modes would let you:\n\n- **Mask Vertices** (Vertex float)\nSame behaviour as sculpt mode.\n\n- **Mask Faces** (Face bool)\nWill restrict the masking to only fill in entire faces as completely masked or unmasked. This is far more useful than trying to paint face float values, which will almost always result in a stepping effect.\n\n- **Mask Pixels** (Greyscale image texture))\nThis feature should replace the current “Stencil Mask”.\n\n### Converting Masks\n\nThese masking features are meant for loose and temporary masks, similar to selections in other modes. \nFor more permanent masking for material and texture mixing it would still be preferred to paint image textures and use them as masks in the material.\n\nWith that use case in mind, it would be easiest to implement to convert the mask to another domain and data type every time the masking mode is changed (Similar to selection modes in Edit Mode).\n\nAlternatively we could test a way of abstracting/propagating the selection between those modes but that could just end up as far more complicated, less predictable and for questionable advantages.\n\n### Edit Mode Syncing\n\nAn important task that is tied to this is to convert the mask of Paint Mode to the Edit Mode selection (and vise versa).\nThis way masks can be much more precisely created in Edit Mode.\nWhile switching between Edit Mode should not be required - masking in Paint Mode should be intuitive enough for most cases - some workflows rely on this for painting precise attributes and technical textures.\n\nSo keeping this functionality will be a priority!\n\n(There are even other potential advantages from considering a Paint Mode mask an Edit Mode selection, like assigning materials directly in Paint Mode. \nThe design of #97903 could help in making this more clear.\n\n# Sculpt Mode\n\nIf these masking modes should be included in Sculpt Mode as well is questionable. \nMasking faces and based on an image texture is no use if you are only able to affect vertices with all tools available.\nThe only advantage would be to avoid mask conversion on mode switching (Which shouldn't be a problem) and to allow painting face corner color attributes with the Sculpt Mode painting toolset (Which is not what Sculpt Mode is for. For sharper edges you should increase the amount of geometry or use the bigger Toolset of Paint Mode).", "Measure tool undo repitition\nOperating system: Arch Linux | Kernel: 5.11.8-arch1-1\nGraphics card: GTX 1070\n\nBroken: 2.93.0 alpha | Branch: master | Commit: 715c7462969e6075859f44a64bb4eb68d056345b | Date: Wed Mar 24 11:00:31 2021\nWorked: I also tested it in 2.91 and it is the same issue\n\nIf you draw multiple measurements with the measure tool and then try to undo one it instead undos the two most recent ones.
