Observe that the Irradiance volume now overlaps the Cube, and that due to the non-proportional scaling there is more irradiance influence in the X direction compared to Z.\n\nWhy does this matter? I would think that for architectural scenes you probably want to carefully control the irradiance volume influence distance so that indirect lighting does not extend through the wall into an adjoining room. Furthermore you do want to ensure the irradiance volume does correctly overlap the walls, and in some cases it might be important to position the irradiance probes close to the wall.

This means that the Irradiance Volume requires massive scaling to get it to the correct size (e.g. 200, 120, 100) - hence the Distance must be set to a very small number - specifically 0.01m.\nI note that if I create a file in 2.80 then when setting the Length to Centimetres it does not change the Unit Scale.

In a nutshell, they will be simpler to maintain and manage, but way less powerful and not suitable for complex things like a whole character animation.\n\nHere is a list of the key differences:\n\n| Library Overrides | Dynamic Overrides |\n| ----------------- | ----------------- |\n| Work only on linked data | Work on any data, linked or local |\n| Allows modifying ID relationships | No ID relationships changes |\n| Allows adding complex entities like Modifiers or Constraints | Can only modify simple ‘value’ properties |\n| Are handled on file save/load | Are handled as part of evaluation |\n| Are stored in the ID they affect | Are stored in a different ID |\n| Directly linkable | Linkable only if the ID owning them is linked |\n\nUse cases include:\n* Tweaking some shaders or lamp settings in the lighting stage of a production file.\n* Tweaking the position of a few props in the shot at the animation stage of a production file. *(Note that this would imply a way to export dynoverrides through ID linking too.)*\n* Dealing with giant hierarchies of IDs (see e.g. #96092 ).\n\nConceptually, dynoverrides are also quite similar to animation data, the main difference being that they are stored in a different, not directly related data-block than the one they affect.\n\nOne big change/challenge implied by this project is that linked data become (partially) editable. This will require a lot of changes all around the Editor codebase (to properties drawing code, operators etc.). Support for that will need to be added gradually, so a restrictive list of overridable properties is most likely needed (similar to what is done with liboverridable properties already).\n\n## UI/UX\n\nThe main, basic interaction would happen at properties level, similar to how animation of a property is handled:\n\n- Define a property as dynoverridden (*and where - active scene or active viewlayer).\n- From there on, any editing of the property affects the dynoverride value, and not the actual RNA/DNA value.\n- From there on, creation of an animation would animate the value of the dynoverride.\n\n*Later some similar feature to the `I` shortcut (inserting groups of animation fcurves) could exists for similar properties for dynoverrides.*\n\nA list of dynoverrides (grouped by IDs) is shown in Scene and ViewLayer properties, with additional bulk-editing features. If a dynoverride defined at scene level is superseded by a same one defined in the active ViewLayer, it should be visible (grayed out in the Scene list?).\n\nThere could also be an overview of dynoverrides in the Outliner?\n\nSome questions:\n* Re-use 'teal blue' color of liboverridden properties, or have yet another color for dynoverridden properties?\n* Need a dedicated icon (probably reusing part of the liboverride one for consistency?).\n\n## Technical Design\n> NOTE: Using existing animation system here also needs to be investigated; dynoverrides could simply be animation (fcurves) defined at scene and/or view layers level.\n\n### Data Model\n\nDynamic Overrides can be stored in Scene data-blocks, at two levels:\n\n* A global level, applying the dynoverrides to all view layers in the scene.\n* A per-view layer level, replacing the global one when defined.\n\nEach of these contain a list of dynoverrides, together with some runtime data (mappings) to search efficiently whether a property is dynoverridden or not.\n\nA Dynamic Override contains a pointer to the data-block it affects, an RNA path leading to the affected property in that data-block, and the value of the override.\n\nPotential animation of these dynoverride values: could be stored either as part of the Scene animation data (*simplest solution, not sure about the draw-backs yet*), or into their own animation data at the scene and view layer levels? Latest could make it easier to somehow 'export'/link dynoverrides into other files?\n\n### Evaluation\n\nDynamic Overrides will be evaluated as part of the depsgraph evaluation, after the handling of animation. This implies that they:\n\n* Can be animated, but…\n* Will supersede any animations or drivers defined on the properties they affect.\n\n*How exactly this fits in current and planned design for the Depsgraph still needs to be evaluated.*\n\n## Ideas for Later\n\n### Linking of Dynamic Overrides\n\nFinding out how critical it is to be able to link or export/import those dynoverrides, and how this could be done, needs to be further investigated. This would probably not be part of the initial deliverables though.\n\nAn idea could be e.g. to 'compile' the current set (from current scene and view layer) of dynamic overrides applying to a given ID, and store it with that ID. Then on linking that ID, code could re-use that 'compiled overrides' data and apply it into the active scene, with a specific status flag indicating that they are 'from linked data' (and therefore not editable, not deletable, and not saved in blend file, but rather re-created from linked data)?\n\n### Overrides From User PoV\n\nFind out how much Library Overrides and Dynamic Overrides could be presented as a single override interface to the user, at least at a high level of usability.\n\n### Dynamic Overrides as Variants\n\nOne of the ideas from original design back from 2.80 area was that it would be possible to define different overrides for different users of a same ID, and that the depsgraph would detect this and generate different evaluated IDs then.\n\nE.g. two different objects using the same material could define their own dynoverrides of the material color, and evaluated objects would get different evaluated materials IDs assigned then.", "\"Open Custom Preview Scene\" operator for asset previews\n(Better name ideas welcome.)\n\n**Motivation**\nWhile generally quite useful, the automatic preview isn't always working too well. That's why there is the option to load a custom preview image from a file. But that tends to be cumbersome too: You typically have to open a new Blender file, import the asset, set up the scene (camera, lighting, render settings, etc), render, save the render result to disk and back in the original file, load the rendered image into the asset preview.\n\n**Idea**\nIt would be nice to have a button, say *Open Custom Preview Scene* that opens a new Blender instance with a scene set up for object preview rendering (e.g. the preview.blend, or a specific collection from it). After saving and closing it the original Blender instance could render the preview using it.\nThis is similar to the *Edit Asset* button Sybren implemented recently, which also opens a new Blender instance and reloads the asset library after closing it.\n\n**Possible Issues**\n\nYou may want to set up different scenes for different assets, but you don't want the scene to get lost every time you close the instance. So maybe the .blend(s) with the edited preview setup should be stored somehow (they are small).\nWe could store it in `/tmp/` by default and let users choose a different location in {nav Preferences > File Paths}. For each custom preview scene we store a .blend with a name like `[source_file_name]__[object_name].blend`. \nIf the file or object name changes now, that mapping will be broken. But there could be ways to restore that (in worst case, manually updating the preview file name).\n\n\nNote that I think this should be done in a script, possibly even in an add-on.\n\nPlus, I'd suggest showing a warning when you save something in the temp directory, indicating that the data might get lost.", "Crash when delete linked object in scenes outliner\nOperating system: Windows 10\n\nBroken: 3.6, 3.5, 3.3 LTS, 2.93 LTS\nBroken: 2.91.0\nWorked: 2.90.1\n\nCaused by b0741e1dcbc5e4549e95745b1f1b501f8cd33add\n\nBlender is crash when delete linked object in scenes outliner\n\n1.

We do not want to lose this feature.\n\n**Proposal**: Add a user preference to link 'visible' and 'selected'.

Some fix will be added to Blender 2.93 LTS to at least prevent crashes.\n\nMilestone 2 is not yet scheduled.\n\n---\n\n**Description**\n**Big picture:** \n\nThe insertion of new items in existing RNA collections of override data-blocks (e.g. object constraints or modifiers) was 'hacked' in in early stage of the project and unfortunately never properly reworked before it got into production.\n\nIt currently has a weird implementation and design flows that make it close to impossible to extend in practice (to support e.g. re-ordering, deletions, etc.)\n\n**Goals**:\n* Make current code match expected design of data model used to store overrides.\n* Support more complex operations over collection items (re-ordering, deletion?).\n\n**List Operations Design:**\nUltimately this would include `Insertion`, possibly `re-ordering` of existing (from linked data) items. Supporting `deletion` operation remains an open topic, as it has fairly complicated implications, and is not strictly needed since items can usually be muted/de-activated anyway.\n\n*Implementation comments are in italic below.*\n\n* Current Design:\n**Order of operations defined in the override property is crucial, since if you insert a new item `A`, and then another item `B` after `A`, you will need to use `A` as anchor for `B` insertion.** Insertion:\n***Insertion operations are applied in a separate, second pass after all other override operations have been applied.**** *This is a mistake, insertion and ordering should be applied **before** any other override operation, such that order of items in destination data fully matches the one it had when operations were generated by diffing code). This is especially important for index-based operations or index-only lists.*\n***If items in the collection can be referenced by unique names (e.g. modifiers, constraints), new items can be inserted anywhere, using any other existing item as anchor (insertion before/after that anchor item).*** If items in the collection can only be referenced by index (NLA tracks), new items can only be inserted after existing ones (i.e. after items coming from the linked reference datablock).\n***If name reference is defined, it takes precedence over index reference.*** If no valid reference is found, insertion point is assumed to be first (for insert after) or last (for insert before) position in the list.\n*** ***Current implementation main flaw:** it uses a single reference information, `subitem_local_name`/`subitem_local_index`. This is used to find the anchor item after which the new one (matching current override operation) is inserted, **in local override data**. The one to be inserted is then always considered to be the next item in the list of the local (source, stored-in-blend) override data. This makes `insert after` operation the only possible one currently.*\n*** *Items inserted in local override data have a specific flag, different for each type (e.g. `eModifierFlag_OverrideLibrary_Local` for modifiers, `CONSTRAINT_OVERRIDE_LIBRARY_LOCAL` for constraints, etc.).*\n**Re-ordering:*** Not supported.\n\n* Target Design:\n**Insertion:*** Fix current main issue by adding a third set of subitem data, called e.g. `subitem_storage_name`/`subitem_storage_index`, to be used by insertion operations to find the source item from the local override data used as storage, when re-applying overrides over linked localized data.\n**** *Versioning code could then simply detect that an insert operation has a define `subitem_local_xxx` info, but no `subitem_storage_xxx` one, and re-generate that one from the next item in the list of the local stored override data.*\n***The rest of the current design for insertions should then be fine.** Re-ordering:\n***This should only be supported for lists that can reference items by their names (Index-based ones would be too prone to produce invalid data if linked reference data changes).**Engineer plan:**\n* Research the best way to `do_version` to use existing data model in the expected way for current, already implemented code/supported feature.

[ "'constant' f-curve not working happily with sampled motion blur Blender 2.79b\nAttempting to use 'offset animation' of the armature object to combine separate mocap clips in the NLA in v2.79b: the results appear to imply that the 'constant' curve interpolation results in the object animating between positions, not moving 'instantly' as the curve in the graph would imply.\nScene created in v2.79b 2018-03-22 14:10 build\n\nBasically I noticed a couple of frames of 'bullet time' blur happening in rendered footage, it happens when the armature root moves and/or rotates between positions to align the armature pose from the end of one NLA action to the next, using 'constant' interpolation in the curve editor for the keys. Basically rendering this animation option unusable if one is using motion blur for the render.\n\nI tried moving the key frames to fractional frame positions (frame xx.5), on the assumption that using 'centered on frame' motion blur should miss the object move - it did not, still 2 frames with 'bullet time' blur on the character. The render time for the 1st bad frame only going from 30 odd seconds to over 13 minutes! The second bad frame rendered almost as quickly as the good frames interestingly.\nTried 'starting on frame' and 'ending on frame' for the motion blur (with whole number key frames for the animation again) - still got the issue in differing frames but basically the same, except that the blurry character jumped positions and back again which didn't happen using 'centered on frame' motion blur.\n\nHappens on all my computers.\nAll machines are Windows 10, 2 x Pro and 1 x Home.\nBox 1: HP Z800, 2 6 core Xeon, 80Gb RAM, 2 x gtx 1070\nBox 2: Dell R510, 2 x 6 core Xeon, 32Gb RAM, 2 x GTX 970 (external on mining risers)\nBox 3: Gigabyte Aero15, 1 x 6 core i&, 16Gb RAM, 1 x gtx 1060 6Gb (win 10 Home)\n\nIf this is a feature, not a fault, then fair enough (although it makes life harder!).\n\n\nCheers\nMark\n", "Curve draw tool: taper setting can lead to wrong handles / random tilt behavior\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15\n\nBroken: version: 3.3.0\nWorked: never\n\nCurve draw tool: taper setting can lead to wrong handles / random tilt behavior.\n\n[#103879.blend](T103879.blend)\n- open .blend\n- draw quick roundish strokes (all should be good at this point)\n- change Taper Start to something non-zero (I set it to 0.05)\n- draw quick roundish strokes again\n- notice \"wrong\" handles\n\nIf I draw a curve like this\n{[F14175937](image.png) size=full}\n\nthen looking at to neighbors (and their handles)\n{[F14175942](image.png) size=full}\n{[F14175944](image.png) size=full}\n\nMakes me think that while the placement of the points are OK, their computed handles are wrong.\n\nTesting more, it seems this is caused by the `Taper Start` being non-zero:\n[#103879.webm](T103879.webm)\n\n**Original report**\n\nCurve Tilt seems to be broken when using tilt.

Adding a third dimension is not trivial and we need to think about how to do this best. Possible solutions:\n* Add an `invoke_3d()` and/or `modal_3d()` callback to operators. Downside is that C-defined operators need this callback to be implemented in C too, it can’t just be implemented in Python.\n* Add wrapper operators (possibly in Python) which only call the wrapped operators to apply the operation. May not work well with modal operators and Python wrappers are limited by the Python API capabilities.\n\n**How will picking with controllers work?**\nWhen users point into the VR-space with a controller, we need to figure out what it is pointed at.\nNote: We can probably fake some picking feedback while no operations are invoked, i.e. we can draw a little dot on surfaces the controller points at with help of the depth buffer of the current frame.\n\n**How should the abstract VR actions (like “Teleport”) be implemented in our event system?**\nThere’s a good chance we’ll offload VR rendering onto a separate thread with its own main-loop. Should we query and handle actions there, separate from the usual event system?\nAlso, some information we’d want to update for every frame, e.g. the controller position and rotation. So this is not event driven like the rest of Blender. How can this information be dispatched to modal operators (e.g. so that the transform tool keeps updating the object position as the controller moves).\n\n**How to implement 2D elements for 3D?**\nFor VR GUIs, we’d want to display quite a few 2D elements in the VR space. For example pie menus, popups and all kinds of regular widgets (checkboxes, number buttons, etc.). Of course, they’d have to be interactive, too.\nIt may also be useful to allow displaying any editor of Blender as floating plane in the 3D environment and allowing interaction with controllers.\nNote that this should never be the prominanting way to interact with the Blender UI in VR. It’s just something that can be implemented without too much trouble while being useful to workaround limitations of the VR UI, without having to take off the HMD.

The [BMesh subdivide edges op ](bmesh.ops.html#bmesh.ops.subdivide_edges) returns three lists of geometry, one of which is 'geom_inner'. It appears that this list doesn't always contain all new 'inner' edges. This depends on the topology being passed to the op. Example image, created from the attached blend file:\n\n\n\nOn the left is the original selection of edges being passed in to the op, and on the right - selection of edges from the resulting 'geom_inner' list. As you can see, some of the edges aren't selected (i.e. they were not present in the list). We can work around this by iterating all **vertices** from 'geom_inner' list, and taking all edges linked to them that are not also part of the 'geom_split' list returned by the op, but it feels like this information should just be provided in the 'geom_inner' list.\n\nLoad the attached file and run the script.\n\n[subdivide_geom_inner_issue.blend](subdivide_geom_inner_issue.blend)", "Click-and-Drag the Cursor with Snapping enabled and an Active Object selected missplaces the Cursor\nOperating system: Linux-5.2.9-125.current-x86_64-with-glibc2.9 64 Bits\nGraphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.40\n\n\nBroken: version: 2.80 (sub 75)\nWorked: None so far\n\n\nDragging the cursor and snapping it to a Vertex while having the Target set to Active makes the cursor snap to a point in space that is directly related to where you start your *click-and-drag* instruction in reference to the selected object's origin. \n\n1) Change snapping to Vertex, Edge or Face\n2) Change snapping target to Active\n3) Set active tool to Cursor\n4) Activate snapping during transform\n5) Select default cube\n6) Drag Cursor over cube\n\n**Important notes**\n\n- If you deselect everything it works, but while there's an object selected the snapping won't work.\n\n- The problem also happens in Edit Mode, but only if there's an object selected in Object Mode.

Now it simply uses the face normal. But this is an issue when the particles collides on the edges or verts of the triangles. This leads discontinuities in the collison mesh as the transition area between the faces is not smooth.\n- - [x] Make colliders be able to push particles along even if the dampening or friction is so high that the particle will not have any velocity.\n- - [ ] We will probably have to track acceleration in addition to velocity to get high quality simulation (like in the old particle system).

But as per Howard_Trickey's comment, 2 Sep 2020 on 160, I'm adding this data point to aid debugging, and if I can get any advice, so much the better.\n\n[AsymmetricUnion.blend](AsymmetricUnion.blend)\nThe attached file contains two mesh objects. If you select \"Verticals\" and then add a modifier to \"union\" it with \"Horizontals,\" then the result is calculated correctly. However, if you do this in reverse—select \"Horizontals\" and union it with \"Verticals\"—then the result is missing some pieces.\n\nIn this case, of course, the obvious fix is to just do it the first way! However, this minimal example is part of a scripted sequence with lots of Boolean operations, and if I can find out why this (the second method) is failing, there might be some hope of getting the script as a whole producing the right output.\n\nI've tried I think every permutation of fast/exact, self and hole tolerant.\n\nAfter looking through some of 160, I've also tried joining the two objects into one, and then calculating the self intersection under edit mode rather than via a modifier, and that DOES work correctly. Are the modifier booleans still the old code, before Howard's marathon revamp of the boolean calculations? In that case I may be fine just using the edit mode functionality, if it's all exposed in the Python API. I can't see how to find the intersection or difference of two meshes via edit mode though; there are buttons for the three boolean operations, but I don't see how to specify the second operand.\n\nThanks!", "Booleans causing shadow artifacts in solid render mode\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.14830 Core Profile Context 21.4.1 27.20.21002.112\n\nBroken: version: 3.0.0 Alpha\nWorked: Unknown\n\nI built up a random shape using a bunch of booleans via the box cutter addon.\nThis seems to have introduced artifacts when the shape is viewed from certain angles.\n\nThe artifacts remain when applying all the modifiers.

The vertices created by the by the bisection are mapped to the original mesh data in a way that appears to be based on blenders internal representation of the mesh and not based on something observable to the user.\nThe behavior when selecting should feel consistent to the user. To fix this, I suggest that the vertices created by the bisection should always map to the vertices on the original mesh that are on the removed side of the bisection plane. This way users would be able to tweak the centerline of the mirrored mesh in while using \"On Cage.\" As it is currently implemented, there are vertices that affect the mesh that cannot be accessed through normal click selection unless \"On Cage\" is off.\n\n**Example**\n\n\nSelect the +X or -X face of the default cube and scale it by 0.5.\nAdd the mirror modifier and select bisect for the X axis so that the object is mirrored and bisected about the X axis.\nTurn on \"On cage\" for the mirror modifier then enter edit mode for the object.\nWhen selecting the vertices on plane X=0, you should notice that two of the vertices correspond to visible mirrored vertices and two correspond to vertices removed by the modifier. \n\nSimple scene showing the behavior. \n[MirrorSelectOnCagePapercut.blend](MirrorSelectOnCagePapercut.blend)\n", "Generic way for modifiers to check user-edited flags\nThe simulation modifiers need to take care of invalidating cache when user edits are performed on the modifier itself, or its dependencies.\n\nFor the point cache (rigid body simulation, for example) this is done as a dedicated dependency graph node, which is hooked to the rest of the graph via a relation which has `RELATION_FLAG_FLUSH_USER_EDIT_ONLY` flag. The benefit of such approach is that a generic callback function can be used (without capturing any internal state of the graph). The downside is the more complex routing of relations.\n\nThe simulation nodes took a bit different approach: the nodes modifier has a special lambda callback which checks the node and dependency graph state:\n```Cpp\nmodifier_node->evaluate = [](...) {\n if (modifier_node->flag & DEPSOP_FLAG_USER_MODIFIED) {\n ...\n }\n}\n```\n\nSuch approach allows to access the modification state without extra nodes and relations, but it is not very generic: ideally the modifier-specific logic will be left to the modifier's \"apply\" callback.\n\nFortunately, there is a simple modification to the current nodes modifier callback we can do!\n\nGeneral idea: have a generic modifier node callback (for all node types) which will copy the user-modified flag from the modifier dependency graph node to the modifier data. The modifier's \"apply\" callback then can make decision based on this flag.\n\nPseudo-code of this proposal goes as following:\n```Cpp\nmodifier_node->evaluate = [modifier_index = ...](::Depsgraph * /*depsgraph*/, ...) {\n ModifierData *md_eval = object_eval->modifiers[modifier_index];\n if (modifier_node->flag & DEPSOP_FLAG_USER_MODIFIED) {\n md_eval-> flag |= MODIFIER_USER_MODIFIED;\n } else {\n md_eval-> flag &= ~MODIFIER_USER_MODIFIED;\n }\n}\n```\n\nUse the modifier index since it can be captured at the graph construction time, and will stay available even if the original objects are destroyed (the long-term goal is to allow the depsgraph be fully independent from the original scene after its Copy-On-Write was run). It is a bit annoying to do an index-based lookup in the list, but it is unlikely to show up in a profiler.\n\nThe geometry node modifier can immediately use this new flag. In a longer term the rigid body will do the same or be migrated to the new simulation framework :)\n\n", "Exact Boolean with Incorrect Result - multiprecision/float round trips not exact\nOperating system: Windows 64 bit\nGraphics card: Nvidia GTX 750 Ti\n\nBroken: 2.91.0 Beta dca36a8ec922\n\nAnother case, where the exact boolean does not work as expected.

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested." ]

A simple example is the \"OK?\" you get when deleting an object by pressing the \"x\" key. The fact that doing so by pressing \"Delete\" instead does not warn is integral to this proposal.\n\nSome of these operators define a property called \"confirm\". `OBJECT_OT_delete` then uses an \"invoke\" callback called `WM_operator_confirm_or_exec` that checks this property and, if set, will show the confirmation message.\n\nIn the keymap editor we see this property as a \"Confirm\" checkmark. In this case \"X\" has it enabled and \"Delete\" has it disabled. We usually justify this difference because the \"delete\" key is nicely separated from other keys while \"x\" can more easily be hit accidentally.\n\n**Immediate Issues**\n\nThe Modelling module has brought up that some operators have confirmations that cannot be configured. These are mostly operators that have their \"invoke\" callback set to `WM_operator_confirm`. That function does not check for a \"confirm\" property and so asks for confirmation every time and cannot be turned off in the keymap. These include \"delete keyframe\", \"delete bone\", \"delete curve\", \"delete track\", \"delete marker\", \"separate bones\", \"separate curves\", \"delete mask\", \"make vertex parent\", etc.\n\nA simple solution to this is to simply fix the operators as needed. Each can call `WM_operator_properties_confirm_or_exec` to add the \"confirm\" property, and then use `WM_operator_confirm_or_exec` for \"invoke\" instead of `WM_operator_confirm`. This would then allow these confirmations to be turned off in the keymaps.\n\n**Proposed Solution**\n\nI don't think these should be configured in the keymap. Most users would find it very difficult to do so. And it doesn't seem to fit this kind of preference. If I desire a warning about an operation it is about the _operation itself_ and not the way it was launched.\n\nI think we should abandon the use of having an operator \"confirm\" property and instead move this configuration to a new section of user Preferences. I think we should have a new \"Warnings\" section with checkmarks to allow quickly enabling and disabling.\n\nIt is worth considering making this more than just a binary choice. For example, it might be nice if `OBJECT_OT_delete` could allow a choice between \"Never\", \"Always\", and \"When more than one selected\". \n\n**Longer Term**\n\nUltimately, I would prefer that more operators have optional confirmations, disabled by default. That is the reason for #106691. And have a fairly large \"Warning\" Preferences section that allows users to make Blender suit their needs.

It seems that Cycles is only partially recognising changes made to the scene in the pre_render, pre_frame, and post_frame handlers. \n\nIn the below zip file there are 3 directories, each containing a blend file with a simple script to demonstrate the issue. The script changes the file output node's base path, and it also changes blender own render.filepath in the output properties panel. The new file name includes the scene camera name (which changes on frame 1 and 3 using markers) and the frame number when the handler updated the filepath/base_path properties, followed by the __0001 added by Blender. For example frame one should read: left cam_updated_path_on_frame_1__0001.png\n\n**Steps to reproduce problem**\n\n\n\n - Unzip [cycles handler bug.zip](cycles_handler_bug.zip)\n - open each of the blend files in place (use 'load UI' as I've set up the workspace for the easiest testing)\n - notice that the blender output is set to 'not set yet', as is the file output node in the compositor.\n - choose to render the animation\n # In the folder where the current blend file resides there will now be two additional folders, one for blender's output, and another for the file output node's results.\n\n\n**Results**\n\n**pre_render handler**\n\nAs expected the camera is incorrect because the pre_render handler happens before the scene has been evaluated. Although strangely some of the information is for the unevaluated frame that the playhead has just moved to (the frame number) and some is for the frame the playhead was on prior to beginning rendering (the camera name which was active on frame 4 before the playhead moved to the beginning of the animation ready for rendering in this example).\n\nBlender's own image sequence output does use the new path which was assigned whilst in the first frames pre_render handler, but on the first frame, the camera name is incorrect and the frame number is correct:\n\n\nThe file output node images however show that cycles didn't recognise that the base_path property had been updated until the next frame. We can see here that the file ending in __002.exr was updated on frame 1, but not used until frame 2, and this continues all the way through.\n\n\n\n**pre_frame handler**\n\nStrangely, although this handler also fires prior to the scene being evaluated (directly after the pre_render handler), this time Blender's own output shows the camera name is now correct, but again, the updated file output node is still not being used until the following frame:\n\nblenders output:\n\n\nfile output node's output:\n\n\n\n**post_frame handler**\n \nBlender's output again is correct, but the file output node's new path is not being recognised:\n\nBlender's output:\n\nFile output node's output:\n\n\n\nThe above can be worked around with code by grabbing the camera from the marker list instead of the active scene camera, but one really major issue for us is that even when locking the viewport prior to rendering, if we update the file output node's base_path, we start experiencing occasional Access Violations and instant crashes, this happens even if the file output node's path is not visible to UI. (perhaps this is related to the reason why the base path isn't being recognised until the next frame?)\n\n\n", "Eyedropper for props does not work in dialog boxes\nBlender 2.81, 71f2229b0d82\nfor example, in Texture Paint Context Menu\nI wanted to implement something using Operator and context.window_manager.invoke_props_dialog()\nThis is not a bug, but why not do it at the dialog level.\n", "Viewport animation render crashes when collapsing the viewport.\nBroken: version: 2.91.0 Beta (and 2.83, 2.80, ...)\nWorked: never\n\nViewport animation render crashes when collapsing the viewport.\n\n[0001-0485.mp4](0001-0485.mp4)\n[Viewport render crash.blend](Viewport_render_crash.blend)\n\n", "Additional unwanted objects being created when asset browser asset is used\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: NVIDIA RTX A4500/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15\n\nBroken: version: 3.5.0\n\nAdditional duplicate (unwanted) objects being created when using assets from the asset browser.\n\nI haven't managed to consistently reproduce how I get this issue to happen.

This includes better handling of thumbnails, re-configuring the ID browser to allow for asset browsing, a nice UI widget for managing tags and tag-based filtering.\n\nA key part of making the UX nice, is to make it effortless to drag assets into the scene. When dragging in objects & meshes, they should be able to snap to surfaces. When dragging in materials, the underlying target objects should highlight on rollover. You should be able to add multiple assets at a time. \n\n**Milestone ?: Collection Variations**\n\nNot strictly part of the asset manager since this would be a core feature of Blender also usable without the asset manager. We would like to support variations for all datablock types, but the first step could be collections (it's effectively like automatically toggling visibility on subcollections to show only one). \n\nOnce this is in the place, the asset manager will need to be modified to understand variations.\n\n**Milestone ?: Project Repositories**\n\nUp to this point the asset manager will handle only the use case of appending files from a local or online repository. The next step would be making it works also for projects.\n\n* The root project directory would contain a `.blender_project` file indicating that it is a project (similar to e.g. `.git`)\n* When opening a .blend file within the project folder, Blender will automatically know which project it is part of\n* Folder structure, file names and file saving are left to the user. The asset browser will not add or remove .blend files in the project. That's all done using File > Save and file browsers as usual.\n* The assert browser will have a \"Project\" repository that can be chosen, which will show all assets within the project\n* The user will have to mark relevant datablocks as assets in each .blend file in the project so it shows up in the asset browser.\n* Assets can be linked between files within the same project. This is different from other repositories, where only append is possible. Linking between projects or to other repositories should not be possible, a project must be self-contained and not link to any .blend file outside of it.\n* The project folder would be indexed exactly like other asset folders.\n\nThe idea here is that we don't want to make many assumptions about how users might structure their project. It should be possible to simply add or remove files, reorganize project directories, and the asset browser should keep working. It will merely provide a view on the existing project structure, and functions to create links to other assets in the project. It will not introduce an alternative linking system as an earlier iteration of the asset manager design did.\n\nThis system does not preclude a studio from making an add-on that takes more control over file saving, version control, partial repository checkouts and so on. Such an add-on would likely need to integrate in various places in the Blender user interface, one of which can be the asset browser. For example it might include a custom asset repository to browse assets that are not on the artist's computer, and right before the user links an asset into the scene, download the corresponding .blend file.\n\nBut for most projects that are not e.g. feature films, the built-in project repository and automatic indexing system should already be quite powerful. \n\n---\n\n**Further links**:\n* [Asset Manager]] design blogpost*-- March 2020** [[ https:*code.blender.org/2021/06/asset-browser-project-update/ | Asset Browser Project Update ](https:*code.blender.org/2020/03/asset-manager/) *-- June 2021*\n* [Asset Browser Workshop Outcomes ](https:*code.blender.org/2021/06/asset-browser-workshop-outcomes/)*-- June 2021//\n* #54642 (Asset Project: User Interface)", "NVLINK two 3090s are slower than a single 3090 when SLI turned on.\nOperating system: Windows\nGraphics card: RTX 3090\n\nBroken: 3.3.2\nWorked: \n\nI'm very late to realizing this issue but once I pegged it I knew it was always there. Long time blender user, I've normally rendered in Houdini/Redshift but I've switched to rendering in CyclesX ever since I saw that you could distribute memory across two 3090s via NVLINK. I'm jumped on the opportunity and have been working this way every since. Having 48 gb of VRAM has opened a lot of workflows for me. However, I was always susipicious of my render speeds. The thing is a single 3090 is so fast anyways that I never really thought much of it. However today I was trying to do some renders on both of my machines, one has the two 3090s connected via NVLINK and the other has a single 1080 ti and single 2080 ti. \n\nEssentially the computer with the 2080 ti and 1080 ti was out-performing the machine with two 3090s by about 15%. This caused some alarms to go off in my head so started to test it out on multiple projects and it was always the same case. The 3090s machine was slower. (purely talking about the sampling speed, I always has persisted images turned on)\n\nSo I tried a couple of things. I tried turning off the check box for distribute memory across gpus and that didn't really do anything. I tried checking off one of the gpus in system settings and that made it even slower.\n\nI thought about unplugging the nvlink bridge but figured that would be a lof of work and if this was a normal situation then I would want a faster solution. This led me to the Nvidia Panel. In that app I was able to quickly turn off SLI connection (I was under the assumption that didn't do anything anymore but I guess I was wrong).\n\nBasically, once I did that my render times were extremely fast. Renders that were taking 1:09 were now rendering around 18sec. Which made sense to me because two 3090s should be much faster then computer with a 1080 ti and 2080 ti (that rig was about 45sec for the similiar render). However, now that SLI was turned off I tried one of my bigger files and noticed, as expected, that it could barely handle the number high resolution textures it had because the VRAM limit was now down to 24gb.\n\nSo I came to conclusion that although with NVLINK you do get the VRAM increase but at a severe cost to performance. Is this the case? Or is this a bug?\n\nIn either case is there going to be attempt to rectify this? I was okay with a slight performance hit but this is more than twice as slow.

This causes issues when adding lamps to the scene with add object (#20275) or adding new lights via libload (#27030).\n\n**Some possible solutions:**\n\n**Recompile shaders when the number of lights change.** The problem with this is recompiling shaders can be slow, especially with lots of materials and no shader cache (I think only NVIDIA cards have a shader cache at the moment).\n\n**Change where shaders get light data from.** We could pass an array of light structs (e.g., via uniform buffer objects) to shaders. This would allow us to change the number of lights in a scene (up to some maximum array size, unless we do texture objects, but that seems silly) without recompiling shaders. Unfortunately, this would introduce looping and branching into the generated code, which could slow down our shaders.\n\n**Move away from forward rendering.** Techniques such as deferred/inferred rendering/lighting grab light data from a buffer that is filled at render time. This allows for a lot of dynamic lights, but we probably wouldn't want to drop our forward rendering, so this would only be a partial solution." ]

This not only slow, but also very hidden, and the Alt-key conflicts with Emulate 3 Button Mouse. Lastly, it isn't clear at all to users which values work for multi-editing, and which values don't.\n\nHere's how we would like to solve it:\n\n\n## Selection vs Active\n\nThe concept of ***active*** in Blender means that we only show properties and only affect the active object or item. However, if we want to better support multi-item editing, we must start by making it so the Properties reflects the ***selection*** rather than the ***active*** item, of which there can only be one. Going forward, by default the Properties will be set to reflect the selection instead. This could be controlled in the Properties like so:\n\n{[F8363009](Screenshot_2020-02-22_at_17.34.54.png), size=full}\n*(The search box is added here to reflect how the Properties will be updated when that item is also added, but is a separate feature)*\n\nIf set to ***Active***, the Properties will continue to function as it does today, only showing properties for the active item.\n\n## When there are multiple selected items\n\nWhen the user has selected multiple items, a few things change:\n\nInstead of showing the name of the object at the top, Blender tells the user how many items are selected:\n\n\nIn the list of tabs, only properties sections are shown that are common among the selected items. For example, if you select a text and a mesh object, we don't show Modifier, Mesh or Curve Properties, since these properties only exist on a subset of the selected objects:\n\n\nThis rule also goes for individual panels. Here, both a Sun and Spot light are selected, and we only see properties that are shared between them. A note at the bottom clarifies that you are only seeing the shared subset:\n\n{[F8364914](Screenshot_2020-02-23_at_18.49.33.png), size=full}\n\n## When values differ\nWhen multiple items are selected, Blender will compare values to check if they are the same, or if they are different. If they differ, we change the way properties are displayed, like so:\n\n{[F8363037](Screenshot_2020-02-22_at_17.52.51.png), size=full}\n\n\n\n## Manipulating values across multiple items\n\n\n\nFor simply setting a value to be the same. you would simply type a new value, hit Return, and that value is then propagated to the selection.\n\nFor manipulating numbers and sliders relatively, you can just drag on them (like Alt-dragging today), or type the character '=', so the user can type '= -3' to subtract 3 from the value on all selected items.", "Unify Interpolation In Vertex Paint And Sculpt Mode\nVertex paint squares colors when it interpolates, while the paint tools in sculpt mode do not.

This is the first keyframe of the first F-Curve in the Graph Editor. In the original prototype, when multiple keyframes were selected and the values did not match, the value's label included an asterisk (*) decoration to show the user that they would be editing multiple keyframe values. @dr.sybren requested that another method is explored as it should be implemented in a wider scope than the Graph Editor. **User Interface feedback requested.** In an animation module meeting @JonMatthis proposed a light blue field decoration.

[ "Properties UI: Multiple objects\nThe Properties Editor is for editing the settings and properties of datablocks in Blender. \n\n\n**The Issue**\nThe properties can only act on one item at a time. If you've selected five objects and want to change the same setting across all five, you've got to jump through hoops to make it possible:\n\nEither, you can use the Copy menu to copy settings from active -> selected (only works for a few settings)\nYou can also right-click and select Copy To Selected, which copies the given setting from active -> selected\n\nHere's why this is a problem:\n\n\n\n - Having to right-click and select Copy to Selected on *every* property *every* time you change it is inefficient, and not fun\n - It doesn't work for some things, like adding modifiers, setting up rigid bodies etc\n - It's quite complicated solution and is hidden\n - Some tools have been added to work around this limitation (Rigid Body Tools) whose only reason for being is to apply certain settings to multiple objects\n\n**Proposed Solution**\nMake the Properties Editor act on multiple selections. Display a '-' symbol for settings that differ, and display the value for settings that match.\n\nAdvantages:\n - No need to right-click and select a menu item for every single property change\n - It's clearer and simpler for the user\n - This way we don't need separate 'tools' such as Rigid Body Tools just to apply settings to multiple objects\n\nExample:\n" ]

The modifier would remain, but would likely be used less.\n\nThere are a few reasons for this:\n* OpenSubdiv GPU acceleration in the viewport and adaptive subdivision in Cycles need the modifier to be last in the stack. The available settings, behavior and implementation would be more clear if this was controlled outside of the modifier stack.\n* When we add modifier nodes support, the concept of a last modifier in the stack becomes fuzzy. Being able to pass along a subdivision surface Mesh to another node without actually subdividing is important for performance and to leave subdivision to the renderer.\n* For best performance with GPU acceleration, we don't want Blender to also subdivide the mesh on the CPU at all. But operations like hair positioning, particle emission and snapping still need to take into account the subdivision surface. If the Mesh datablock contains all the subdivision surface information, these could potentially work on the limit surface without subdividing the mesh on the CPU.\n* Simpler smooth normals handling, see #68893 (Smooth shading usabilty).\n* File formats like USD have native subdivision surface primitives. By making it part of the mesh, we are more compatible with such file formats. \n\n\n**TODOs**\n\n- Modeling\n - [ ] conjugate the presence of a subdivision surface modifier with the mesh settings if it is the last in the stack\n - [ ] ensure creases survive the modifier stack (unless consumed by a subsurf modifier)\n - [x] (follow up to [D10145: Subdivision: add support for vertex creasing](D10145)) move edge crease to a custom data layer\n\n- Cycles/EEVEE\n - [x] detect subdivision using the mesh settings instead of the modifier\n\n- Normals (work on some aspects of #68893 (Smooth shading usabilty))\n - [ ] remove autosmooth and custom normals options if the mesh is a subdivision surface\n - [ ] always render with smooth normals (flat areas can also be defined trough creasing)\n\n- Alembic/USD\n - [ ] set mesh settings during imports\n - [ ] export as SubD Object when subdivision is used\n\n- Workflow\n - [ ] option to set the subdivision settings when creating a mesh, or add a sub-menu with meshes with subdivision enabled\n - [ ] shortcuts to subdivide (?)\n - [ ] script/addon to update old files to replace last subdivision modifier in the stack with mesh settings (doing this in version code might have undesirable side effects)\n\n- Other\n - [ ] Update test files", "Crash with animated displacement modifier in Texture paint mode while playing\nAMD Ryzen 5 2600, 16GB ram\nWindows 7 64bit\nNvidia GTX 1060 6gb (driver version 416.34)\n\n2.79b\n\nI intend to paint a heightmap interactively.

[ "Split up pose mode keymap to avoid weight-paint conflicts\nCurrently the \"Pose\" keymap us used in combination w/ weight paint.\n\nThis means we can't add key bindings for animation that conflict with weight painting for eg. F-Key. See: #63667 (Keymap: Weight Painting using the Pose Mode keymap)\n\n----\n\nProposal:\n\n- \"Pose Generic\" for basic selection operations.\n- \"Pose\" for more advanced animation actions.\n\n\"Pose Generic\" would co-exist with weight paint mode when weight painting is mixed with pose mode.", "Attribute Edit Mode\nThis is an extract from the now archived Vertex Color/Attribute Edit Design (#71947).\nThe design needs further investigation an discussion with the #geometry_nodes module.\n\n## Attribute Edit Mode\n\n\n\nAttribute Edit is intended to be a mode to modify and visualize any kind of data stored in mesh elements. Some use cases for it could be:\n\n- Editing IDs on face corners to modulate materials in a shader\n- Painting velocity vectors on vertices to guide a particle system\n- Editing the weights of a rig\n- Editing per face colors for low poly models without using textures\n- Setting custom values on edges for a motion graphics animation\n- Modifying mesh values for procedural modeling\n\nSome of these task could use a brush, but they don’t need a brush with artistic painting functionality. It does not make sense to edit the weights of a rig with a brush with wet paint and density noise.\n\nFurthermore, these task could take advantage of a mode with more control and precision tools than an artistic painting mode, like precise elements selection and data editing, controlled value interpolation…\n\nThe plan is to use the current Vertex Paint mode as a base implementation for this mode and start adding all necessary features during multiple releases. It already has quite some work done because most users were using it with these use cases in mind.\n\nThis task is not as detailed as the Sculpt/Paint mode, but it should be enough to have an idea of its purpose, use cases and design goal.\n\n### Tools\n\n**Simple brush tools**\n\nThe current Blender brush functionality is enough to support this kind of painting, if we consider painting changing the values of elements that are inside the cursor radius. We can reuse the current brush code for that.\n\n**Value interpolation tool**\n\nThis tool could produce controllable interpolations of an attribute between two mesh elements following the mesh topology. For example:\n - Select the base of a cone and assign the value of one \n- Select the top vertex of the cone and assign 0 \n- Let the tool generate the rest of the values across the cone surface\n\n**Mesh elements selection**\n\nAttribute paint should provide tools for selecting mesh elements and assign values directly to them. This provides much more control than a brush. This could be useful when working with low poly models, where you want to assign values like armature weights in a precise way.\n\n**Mesh element masking**\n\nWe can support a basic masking functionality for the brush that supports all mesh elements (not only vertices like the Sculpt/Paint mask). This can make easier some painting task.\n\n### Features\n\n**Data conversion operators**\n\nAttribute edit mode should provide a set of conversion tools to convert data between elements and other Blender data layers when possible. For example:\n\n- Convert a per vertex attribute to a per face corner attribute\n- Convert a per edge attribute to a vertex attribute averaging the\n```\n values\n```\n- Generate material slots from an ID attribute stored on faces\n- Generate an editable 2D vector attribute from an UV layer\n\n**Per face corner color data to sculpt/vertex color data**\n\nThis is a specific case of a conversion operator. Other conversion operators can be added in the future as we support more attribute types.\n\n**Internal attribute conversion**\n\nWe need to identify what element/attribute type conversion combinations are more frequent and design how they can work (usually averaging the values). For example\n\n- Converting an attribute from face corners to faces by averaging the\n```\n values of all the face corners in the face\n```\n- Converting from vertex to edges by averaging the value of the two\n```\n vertices of the edge\n```\n- Converting from vertex to face corners assigning the same vale of\n```\n the vertex to all the face corners that use that vertex\n```\n\n**Topology symmetry**\n\nWe could support editing operations with symmetry based on the mesh topology instead of mirroring the XYZ axis.\n\n**Attribute data type selection**\n\nThe use should be able to choose what kind of data he/she wants to edit and in which mesh element that data should be stored. For example\n\n- A float factor stored on faces\n- A vector stored on vertices\n- A color stored on face corners (Current supported MLoopCol)\n\nAll tools should be aware of the data type of the layer and behave accordingly.\n\n**Import/Export**\n\nIt should be possible to import and export meshes with different attributes in mesh elements. We need to check format compatibility.\n\n### Rendering\n\n**Attribute edit overlay**\n\nAs we can make assumptions that the attributes are colors, we need to render a configurable overlay to display the data in an appropriate way.\n\n**Attribute rendering mode selector**\n\nThe attribute rendering overlay should provide and UI to choose which rendering mode the user wants to render the data. This should include tools like a gradient editor, rendering two attributes at the same time, render vectors and randomly generated ID maps.\n\n**EEVEE/Cycles attribute node**\n\nThe current attribute nodes exposes MLoopCol and UVs to the render, which are both loop attributes. We need to investigate how to expose face, vertex and edge values.", "Selection not transfering to paint mask (vertexpaint, weightpaint, texturepaint) when a triangulate modifier is present\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1660 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.81\n\nBroken: version: 2.92.0\nWorked: -\n\nIf you face select on edit mode, it will carry your selection to weight paint face select or texture paint face select or etc.\nBut if you have triangulate modifier on it will not carry it over.\n\nI did not know this and there was not error message about this anywhere on blender.\n\nLoad this file: [faceselect001.blend](faceselect001.blend)\nyou see some faces selected with triangulate modifier on.\ngo to weight paint or texture paint and you see none.\n\nI know this might not be a bug but how software works BUT for a common artist, at least adding a message that it will not carry over selection would have been nice, or disabling triangulate on view automatically when you go to those modes.\n\n", "Lattices don't display selected vertices with modifier \"Edit Mode\" enabled\nSince 2.8x, lattices have not been displaying selected vertices when the modifier option \"Edit Mode\" id enabled.\n\nThis is easy to test:\n\n- add a new lattice object\n- add a wave deform modifier.\n- enter edit-mode.\n- enable \"Edit Mode\" toggle for the modifier.\n\nThis test file shows the problem too, open it and toggle the \"Edit Mode\" modifier button.\n\n[#77184.blend](T77184.blend)\n\n----\n\nReporting this to keep track of the issue: `BKE_lattice_modifiers_calc` is making a copy of the lattice `lt_eval` which doesn't contain an edit-lattice, which is then used for drawing.", "Weight Paint Vertex Selection Display issue\nOperating system: Linux Mint\nGraphics card: RTX 3070\n\nBroken: latest master\nWorked: never really, more on that below\n\nWhen in weight paint mode with\n* vertex selection enabled\n* show wire enabled\n\nedges will not be drawn within the selection\n\n\n**The odd part**\nClicking in an empty space will get the wires to show again, but keep the vertices selected. \nThat's a behaviour that has changed from 3.1.2 to 3.2.2\nPreviously it deselected the vertices but didn't draw the edges\n\n\n\nBased on the default startup or an attached .blend file (as simple as possible).\n* Open the attached blender file\n* you can see that edges are not drawn between selected vertices\n* click in an empty space (important to click, not click drag)\n* vertices stay selected but wires are drawn\n\n", "Cycles vertex color bump map banding \nOperating system: Win10\nGraphics card: GTX 1070\n\n2.79b release\n\nUsing vertex colors in cycles material as a mask for bump/normal texture causes banding/hard edges in render.\n\nBanding of vertex color is also visible when using it as a color for shader. \n\nIt might have something to do with the fact that vertex colors are represented in 8-bit sRGB values but on the other hand it renders as expected when using it as a mask for example for mix shader node.

When keyframes are dense, the keyframe type becomes almost impossible to see. We agreed that this feature was really useful for organizing the keyframes of a shot, but it needed improvements.\n\n### Current behaviour:\n\n{[F7785806](Set_Keyframe_Type_Visibility_UnSelected_Original_Comparison__copy_1_.png), height=55}\n\n - The size of the keyframe changes, 3 of the 5 options make the icons smaller, making them harder to find\n - The colors are not bright enough.\n - Colors of Selected/Unselected are too similar.\n\n{[F7785842](Set_Keyframe_type.mov), loop, autoplay, layout=left, float}\n\n\n- Keyframe colors become almost impossible to see when there are more keyframes nearby.\n\n---------------------------\n\nSo we came up with a proposal with three main points in mind:\n\n- The user is the one deciding the color/shape\n- Clear colors\n- Clear Shapes (so they are easy to see even for color blind people, as some of them might not be able to differentiate the colors)\n\n### Animation team proposal:\n\n{[F7785822](Set_Keyframe_Type_Visibility_UnSelected_Mock_Up_Comparison2__copy_1_.png), height=50}\n\nThis visualizing way could also propagate to the graph editor, which connects with [D5621](D5621) :\n\n{[F7785827](Graph_Editor_Key_Visibility_Blue_Selected__copy_1_.png), height=250}\n\n\n ---------------------------\n\nBut this proposal fundamentally conflicts with the new way of visualizing the handle type in the dopesheet, as that one changes the keyframe shape as well.\n\n## Current handle type icons\n\n{[F7785830](handletype-current.png), height=50}\n\nFor the animators at the studio showing the handle type in the dope sheet is not really useful, so we keep the option off, but we understand that there are other users that will find these really useful.\n\nI think it's important to understand how we use the dopesheet: \n\n- Since generally every bone has 9 different channels, and we are dealing with a lot of bones in a rig, we keep the channels collapsed in the dope sheet, using the summary or the top channel to make changes, if we want more precise control we'll jump into the Graph Editor.\n\nThe main issues we have with the handle type visualization and the interpolation type visualization are:\n\n### Spring shot file example\n\n{[F7785832](springshotexample.png), height=80}\n\n- When you have a lot of keyframes together the shape difference is so small it becomes really hard to see, becoming more confusing than helpful.\n \n### Open - Collapsed example:\n\n{[F7785835](coolapse-open.png), height=250}\n\n\nWhen the channels are collapsed, the information shown is not reliable. In the example used above, each one of the channels have different handle types and different interpolations. When collapsed there is no single type to be shown, creating misinformation. \n\n---------------------------\n\n## Conclusion:\n\nKeyframe colors are important. We propose an improvement by:\n\n - Clarifying keyframe-type colors and shapes in the dopesheet\n - Suggesting this would be useful in the graph editor too ([D5621](D5621))\n - Offer a switch between handle-type shape and keyframe-type shape (instead of the on/off switch for handle-type shape).\n```\n\n```\n*I’m not not a designer, so this is not final or beautiful design just a proposal to visualize my points. \n" ]

Please don't take it as official document.\n\n## Goals and Overall Vision\nXR enables an entirely new way to work with computer generated 3D worlds. Instead of trying to take the UIs we’ve already implemented for traditional monitor use and make them work in XR, we should establish an experience on entirely new grounds. Otherwise, what we’ll end up with is just a different, more difficult way to use Blender.\nSo to enter the new immersive world, we should think about which workflows could benefit the most from XR, and carefully craft a new, improved experience for them. Don’t try to enable huge amounts of features for XR, risking bad outcome - or even total failure - but find out which features matter the most and focus on them first.\n\nLong term, the experience can then be enriched further, with more features added as smaller, more concise projects. Eventually, XR would allow creating 3D content with unseen interactivity. The entirety of Blender’s content creation capabilities available in an immersive 3D experience. However, this better be the long term vision for XR, not the goal for this initial project.\n\n## OpenXR\n\nAll VR support in Blender will be based on [OpenXR ](openxr), the brand new specification for VR, AR, MR, etc - or short: XR. It is created by the Khronos group and has a huge number of supporters from all over the VR industry. It’s likely going to be the standard for VR/AR/MR/… (XR).\n\nOpenXR splits the workload between the application (Blender) and the OpenXR runtime. The runtime handles all the device specific stuff, provides many common features (e.g. time wrapping) and can add extensions to the OpenXR API. So the devices Blender will support are defined by the available OpenXR (compatible) runtimes. Currently:\n* Windows Mixed Reality\n* Oculus (though, not officially released)\n* Monado (FOSS Linux OpenXR runtime)\n\nFor information on how to test our current OpenXR driven implementation, see How_to_Test\n\n## State of the Project\nWhile there are multiple initiatives related to Blender and VR (e.g [MPX ]] and [[ https:*www.marui-plugin.com/blender-xr/ | Marui’s Blender XR ](https:*vimeo.com/channels/mpx)), the first important milestone for XR support in main Blender is being finished with an ongoing Google Summer of Code project. It aims to bring stable and well performing OpenXR based VR rendering support into the core of Blender. It’s not supposed to enable any interaction, it’s solely focused on the foundation of HMD support. For more info, refer to #71365. Further work is being done to complete the first milestone: #71347 (Virtual Reality - Milestone 1 - Scene Inspection).\n\nThe one important part that’s missing is controller support, or more precisely, input and haptics support. Although we can do some experiments, it would be helpful to first get a better idea of how VR interaction should work eventually, before much effort is put into supporting this.\n\nThis is the foundation that we can build on. It should allow people with experience in the field to join efforts to bring rich immersive experiences to Blender.\n\n## Development Process\nProposal is to do a use-case driven development process. That means, we define a number (say 10-20) of specific use cases. These should be chosen wisely, based on what we think has most potential with XR.\nFirst, just vaguely describe what requirements the system has for a use-case, a bit later on, define what tools and options are needed to get the use case done (possibly by a specific [persona ](personas-why-and-how-you-should-use-them)).\n\nOn top of that, the process should be done iteratively. That means, we define short term goals for an iteration, work on them and evaluate afterwards before we get into the next iteration. The iterations may include implementation work. So we don’t do the waterfall-like “design first”, but there should be enough design work done before first implementations are made.\n\nAny implementation should be driven by a use-case (or multiple) that the team agrees is drafted out well enough.

There are still some actions that have two users but I couldn't figure out which. I'm pretty sure the actions are not related to the crash though but not 100% certain.\n- deleting any one of the four bones \"fixes\" the crash\n- removing the custom shape of one of the bones also \"fixes\" the crash \n- Assigning the `ctrlShape.facial` to all bones seems to fix it as well. The crash may be only with custom shapes with no surface and just wireframe?\n- when one or more of the four bones have the `wireframe` checkbox ticked (above the custom shape thingy), it doesn't crash\n\nSorry again that I couldn't reproduce this in a new scene but hopefully I gathered enough information to make your life easier!\nI'm available if you have any questions and/or want me to test some stuff if you can't reproduce this.\n\nHere's the blend file: [crash_custom_shape_bones.blend](crash_custom_shape_bones.blend)", "Crash when clicking bones in pose mode with specific custom shapes\nOperating system: Windows 8.1 64-bit\nGraphics card: GeForce GTX 860M - Driver Version: 416.94\n\n\nBroken: 2.80, 196dbc0f314e, 2019-15-10 09:55\n\nIn the attached blend file, the crash is triggered by left clicking the 3D viewport in Pose mode.\n\n[armature_crash_bug17.blend](armature_crash_bug17.blend)\n\nClick anywhere in the 3D viewport of the attached blend file.\n\nIt happens only in **Pose mode** in **all shading modes**, *except for Wireframe* view. \n\nI isolated the 2 offending bones in the armature (**eye.lookAt.L and .R**) of the blend file, but left other bones as well for tests.

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", "EEVEE-Next: Refactor renderpass storage\nCurrently render-passes are allocated in multiple texture buffers.\nThey take a lot of binding points and currently prevent the deferred pipeline to output diffuse color correctly.\n\nThe plan is to combine all render-passes into the same array texture and use an associated UBO containing offset to the layer of each pass type.\n\nThis would very similar to the AOV support.\n\nAnother direct benefit of this would be that the GBuffer encoding could be simplified.\n\n", "Mix/Add nodes breaks Eevee AO render pass if one socket is unfilled.\nOperating system: Windows-10-10.0.16299-SP0 64 Bits\nGraphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 419.67\n\nBroken: version: 2.92.0, 2.93.0, 3.0 0efb627bbd\n\nIn Eevee, any material which contains an add shader node will be broken in the AO pass, if second socket is *invalid*, leaving the material either entirely black or white.\nThis is annoying if you're creating entirely black materials by leaving a socket empty.\n\n- Add a mesh, give it a material.\n- Put either an an add shader node or a mix node into the material somewhere, but only fill one of the input sockets\n- Enable AO with Eevee, and look at the AO render pass in render view.

That's because some data is accessed/modified that is not thread safe. E.g. `object_preview_render()` modifies `U.pixelsize`. I think other glitches are caused by overriding the active theme in `ED_view3d_draw_offscreen()` - although when I avoided this some time ago for similar work on threaded offscreen drawing for VR, this didn't solve the color flickering.\nThe active theme should probably use thread local storage.\n\nBesides that, the preview generation should be thread safe with OpenGL:\n* It uses the draw-manager's own context, which is mutex protected.\n* The non-thread-safe immediate mode API is not used inside the draw-manager.\n* The draw-manager already has workarounds for GPU driver issues with threaded drawing.\n\nA note: We could also speed up Eevee preview generation significantly by using viewport render quality, not final render quality.

For Metal (and likely Vulkan too), PSO compilation (backend/low-level compilation) happens on demand, depending on the current render pipeline state in combination with a given shader, and this can take time, introducing stalls and stutters, such as when an object is first selected and the select-engine/depth-only permutation is generated for that particular mesh.\n>\n> Ideally we would want to avoid these one-off PSO stalls, which for OpenGL, are generally hidden behind driver processing. Propose a few options:\n> - Option to add a \"default/fallback shader to a **GPUShader** such that if it needs a fresh PSO, and a default shader/fallback is provided, it can instead bind that shader for the draw. In essence, continue using the EEVEE default material, if PSO compilation is needed, not only when the shader library is compiling.\n> - Shader PSO cache warming: Generate the render pipeline state configurations/permutations up-front to allow background parallel PSO compilation. This could be done by performing a dry-run of Blender and packaging a data-file containing the serialized input structure for the PSO compilation function, and performing background warming after start-up, using this data. This avoids the need to manually specify the configs.\n> - Prepare certain configurations up-front in background by performing dummy renders in different states, and skipping draws which trigger a PSO compilation. This allows the dynamic render state to be set, without performing rendering.\n\n\n * - [x] Metal viewport/Metal Cycles shader compiler load distribution manager. \n\n> As both backends use Metal, there is only a fixed pool of shader compilation threads available. A mechanism should be in place to ensure compilation is not stalled, which could cause the viewport to become unresponsive for synchronous shader compilations. e.g. PSO backend compilations.\n\n```\n\n```\n * - [x] Python -- Use of OpenGL within Python API - Ensure safe fallback (T103863)\n * - [x] Cycles - Live viewport display -- Currently uses OpenGL directly\n\n---\n\n**Relevant links**:\n* `-` Metal-Shading-Language-Specification.pdf\n* `-` metal/\n* `-` Metal-Feature-Set-Tables.pdf", "Asset Browser: Material preview with black background when Cycles is disabled\nBroken: version: 3.0.0, 3.4.0\nWorked: Never\n\nWhen a scene was saved with Cycles but I disable the Cycles add-on the material previews get a black background.\n\n* Disable Cycles add-on.\n* Click on any (e.g., the Yellow) material asset and update its preview.\n[black_preview.blend](black_preview.blend)\n", "Objects with negative and small scale cant be selected using Select Box without zooming.

I have an environment with foliage billboards that appear like they are slightly head-locked and they sway around a lot when moving in VR. I later realised I could reproduce similar artifacts outside of VR and then realised that disabling denoising avoided the artifacts in the editor and in VR.\n\nIt seems that Eevee's denoising introduces some kind of latency related to how the alpha blending is handled which results in temporal, visual artifacts while the viewport's perspective is changing.\n\nI'd say the reproduction below probably doesn't represent how significant the artifacts feel in VR but I think it highlights the same underlying issue (the same two workarounds that affect the editor, also help in VR).\n\nTurn on Viewport Shading: Material Preview or Rendered\n\nDelete cube\nAdd plane\nAdd material (default principled BSDF is fine, though in my case I'm working with emissive shaders and I have a modified build of Blender supporting equirectangular image textures that let me access their alpha channel)\nSet material Base Color to an Image Texture.\nCreate a new image and generate a Color Grid to set as the base color.

This should be the basis for discussions on the implementation.\n\n# Goal\n\nSampling colors is implemented in various different ways throughout Blender, each implementation with their own advantages and features.\nThe goal here is to combine all needed features into an easily accessible operator, with additional options to get other sampling effects.\nThis operator will then be used for color sampling in sculpt/paint mode and paint mode in the image editor.\n\nThe basic implementation in sculpt mode is already usable for now.\n\n# Requirements\n\n## Existing Features\n\n- Sample Merged (Only available in the keymap options or with the color picker button)\n- Add to Palette (Already available via left click)\n- Sample Size (Only in the image editor sample tool)\n- Live sample values for XY, RGBA, CMGB, HSVL, color (Only in the image editor sample tool)\n- Sample Interpolated vs Closest (Automatic for textures. Always picks closest in Weight painting. Not implemented for color attributes. Needs more investigation on what would be most useful.)\n\n## Accessibility\nThe easiest way to access the color sampling should always be with a shortcut.\nFor now the established default is `S`. We should follow this wherever possible to stay consistent.\n\nPotentially the best usable way to implement this in the UI is as a button in the color picker instead of an active tool.\nThe disadvantages of making this an active tool are \n- that it doesn't directly relate to any particular color or brush/tool\n- it's more intuitive to use as a temporary one-click operation (No needs to keep it active)\n\n## Sample other Objects\n\nIt's already possible to pick any color of the screen when sampling merged colors.\nWhen sampling the current paint slot of the Canvas this is not the case.\nMulti-object workflows are very common so there needs to be an implementation to instantly sample local colors from another object.\n\n**Use active Canvas picker mode**\nOne straight forward implementation would be to use the Canvas picker mode of the active object to define which colors will be picked. This mode can be set to:\n- Color Attribute\n- Image Texture\n- Material\n\nEach of the other visible objects will have an active color attribute, image texture and node in the material.\nSo the desired approach is to look for that data and use it for color sampling other objects whenever the option \"Sample Merged\" is not used.\n\n## Color Sample Overlay\n\nWhen painting for materials there will be cases where it is not obvious what color will be picked. \nFor example when picking from a greyscale image texture that is used for roughness, while you see the final material in Eevee with additional colors and procedural roughness textures mixed in.\n\nThis color sampling preview would ideally be shown directly on the brush cursor, comparing it side-by-side with the currently set color.", "Add overlay to visualize full weight values in weight paint mode\nTake the following case in which some vertices are weighted in full 1.0 (RED), some have a weight of 0.0 (Blue) and some are weighted very close to full (0.9) and some are weighted very close to zero (0.1)\n\n\nIn this case it is very hard to visualize which vertices are weighted 0.0 or 1.0 or which are just very close but might have a different influence.\n\nFor that reason we have a **Zero Weights** overlay that uses black to indicate 0.0 weights\n\n\nWith this overlay enabled it is quite easy to distinguish between 0.0 or just very close to 0.0\n\n\nWhat's missing is the same logic but for values of 1.0 where an overlay would show the **Full Weights** in white, 0.0 in black and the rest in the typical colors\n\n\n*Note: The above screenshot assumes the implementation of another [related task ](https:*developer.blender.org/T93147)//", "Texture on active object is not visible in solid view with sculpt mode activated\nOperating system: Windows 10, Ubuntu 16.04\nGraphics card: GeForce GTX 760\n\nBroken: 2.80\n\nTexture is not visible in solid view with sculpt mode activated\n\nCreate a texture, apply it to an object, like start cube, make sure you're in solid view mode with textured color active, you'll see the texture in object mode.

This may be thousands of assets. Further, the UI may request previews for assets, where each preview has a notable memory footprint (around 70kB for each preview at the default 256x256 image size).\n\nAs it stands, Blender is not mindful about this at all. For example simply calling the \"Add\" menu in geometry nodes editors loads all asset libraries into memory (!), including all previews (!) and keeps all this data in memory until another .blend is read (!). This is bad and wasteful design that users have to pay for.\n\n## Status Quo\n\nMemory and asset lifetime is managed rather differently in the asset browser and the rest of the UI (asset shelves, add menus, etc.).\n\n**Current Asset Browser Memory Management:**\n\nThe situation for the asset browser is not too bad (because it's simpler).\n\n- **Good**: Only the currently shown asset library is loaded into memory.\n- **Good**: Previews are lazy loaded into a cache based on the assets in view.\n- **Good**: Previews are removed if the cache is filled with a resonably small amount of previews.\n- **Bad**: Storage is per asset browser instance, so when multiple are open and showing the same asset libraries, storage is duplicated (especially wasteful for the \"All\" asset library).\n- **Bad**: The preview cache is cleared and reloaded often, causing flickering on common interactions (e.g. undo/redo).\n- **Bad**: The preview cache fails miserably with large asset libraries and causes continuous freezes, making the asset browser unusable with large asset libraries.\n\n**Rest of the UI:**\n\n(Asset views, the node add menu, the node search menu, asset-view template, etc.)\n\n- Challenge: Usually use the \"All\" asset library, meaning all assets are loaded when showing such UIs.\n- **Good**: Memory is shared between these UIs (static storage), so libraries are only loaded and stored once. (Asset browser storage is still separate).\n- **Bad**: No lazy loading of previews, all previews are loaded into memory\n- **Bad**: Only freed when closing the file.\n- **Bad**: Previews are also loaded when none are displayed (e.g. node \"Add\" menu)\n\n---\n\n## How to solve it?\n\n### Good solution characteristics\n\nA good solution should give us the following:\n- Only hold asset previews in storaged that are in view of the user\n- Don't keep asset libraries in storage that the user isn't interacting with (at least not regularly, see next point)\n- Provide fast repetetive access to asset libraries (e.g. assets shouldn't be reloaded every time the \"Add\" menu is called in the geometry nodes editor)\n- Support shared storage. All UIs giving access to assets should be able to access the same static asset library and preview image storage.\n\n(Further improvements are possible still, see below)\n\n### Lazy Loading Previews\n\nPreviews should always be lazy loaded based on which assets the user sees, and only if the previews are actually displayed (e.g. not for the node \"Add\" menu). #109234 does most of the necessary work for this.\n\n### Garbage Collector?\n\nA garbage collector could be implemented to remove unused asset libraries and asset previews from storage. Some kind of user-counting will be needed to detect the unused state, even when multiple parts of the UI display the same asset library (and thus may share storage). By being time based rather than user-count based only, the garbage collector still gives enough time for repetitive access to asset libraries. For example the asset library may still be in storage for multiple calls to the node \"Add\" menu, but be freed from storage if it hasn't been called for at least 5 minutes.\n\nNote that this doesn't need to be asset system specific. There are other UI previews that we load from disk that could make use of this. So this could be a more general UI garbage collector.\n\n---\n\n## Possible Further Improvements\n\n## Partial asset library loading?\n\nUsers rarely ever look at all assets of a library. They typically look at assets of a certain type (e.g. in the node \"Add\" menu), a specific catalog, or the view simply only has space for a subset of the available assets. So this is another case where we can avoid keeping data in storage, e.g. by lazy loading assets or deleting them once they are recognized as irrelevant.\n\nKeeping track of which assets are loaded and which have to be made available can be finicky. Plus we may run into issues when asset library contents were updated in-between partial reads.\n\n## Lazy load extended metadata\n\nIn most cases, all the user sees from an asset is the name, and potentially the preview. Keeping all the asset metadata in storage is a bit of a waste. We could lazy load this as well, although this can become finicky too, since some metadata needs to be accessed faster or more frequently (e.g. basic type information, tags for search, etc.) than other.\n\n## Compressed preview buffers\n\nPreview buffers could be compressed to reduce the memory footprint of each, potentially leading to faster load times too.\n\n", "Blender crashes as soon as an image texture is plugged in the material BSDF node\nOperating system: Windows 10\nGraphics card: NVIDIA GeForce GTX 1080 Ti\nSee attached log for more detail\n\nBroken: 3.5.1, but also 4.0.0 Alpha, did not try intermediate versions\nWorked: ???

During the rendering process, I have not encountered any issues, using approximately 20GBs of RAM. However when entering the \"Material Properties\" tab, Blender's memory usage increases. If I remove and readd a material, Blender recalculates all the materials in the scene, and the memory usage increases until my PC runs out of memory and Blender crashes. The memory usage grows this much since I have two UDIMS spaces assigned for the \"Base color,\" \"Roughness,\" and \"Normal Map\" textures, at a 4K resolution.

Change the render engine to Cycles.\n2. Setup the scene for MNEE caustics by adding a caustic caster, caustic receiver, shadow caustic light, and configuring them properly.\n3. Add another light to the scene and ensure the `Shadow Caustic` option is NOT enabled.\n4. Place this new light somewhere in the scene where part of the shadow and caustics caused by the light passing through the caustic caster onto the caustic receiver overlaps with the shadow from the light with the `Shadow Caustic` option enabled.\n5. Ensure the {nav Render Properties > Light Paths > Caustics > Filter Glossy} is set to a value larger than 0.\n6. Reduce the power of the light with the `Shadow Caustic` option enabled so it has only a small impact on the final render. (Note: The power of the light must be above 0 for this to work) - This step is not necessary, but it makes it much easier to see what's happening.\n7. Render the scene.\n8. Compare that render to another render with the `Shadow Caustic` light excluded from the final render. Notice how there was an impact on the shadow and caustics produced by the non-`Shadow Caustic` light.\n\nHere is a .blend file with steps 1-6 done for you:\n\n[#97932 - Overlapping Caustic Shadows issue.blend](T97932_-_Overlapping_Caustic_Shadows_issue.blend)\n\nThe steps for testing with the file is as follows:\n1.

More advanced implementations could include options for alternate, lightweight representations of shapes in the Blender scene, e.g., exploiting instancing, custom viewport rendering that does not require importing the mesh data, etc.\n\n@charlesfleche discussed the following suggestions re USD shape support on the `pipeline-assets-io-module` Blender chat channel on 22 Sep 2022.\n\n---\n\nOur main use case is to represent collision objects. For performance reasons we can feed simple collision objects to the physic component of the game engine. For example, rather that computing a collision with a complex character head that as many faces, you can define a simple sphere that is much faster to compute collision against.\n\nBut sometimes simple shapes are not enough: in this case we still want as fast as a collision computation as possible, and use a convex mesh to approximate the visual shape as much as possible. And when we really, really require high precision we'd use a mesh that can be complex and convex.\n\nWe also have the concept of collision Level Of Detail. The typical example is a fence:\n\n- you don't the player to walk through the fence, but for that purpose you can approximate the shape of the fence with a single parametric box\n- but you still want a bullet to go through the holes of the fence: for collision with ammunitions, you'd use a more detailed mesh\n\nBut not all DCC support parametric shapes, so for simplicity (and for now), we are still importing USD shapes as meshes in the DCCs, but on way back to USD we compute the bounding volumes of the requested shape. In practice, it looks like this:\n\n- In USD: `UsdGeomCube` MyObject_BOX with a size attribute + xform\n- In the DCC: we extract the dimension of the box from the scale component of the transform and generate a box mesh, with custom code ran at import time\n- DCC user is editing the box\n- In the DCC: the object is a _BOX, we compute the Box Bounding Volume and store the x, y, z dimensions as in the xform as scale\n- In USD: `UsdGeomCube` MyObject_BOX wih a size attribute + xform\n\nIt is not great because the users don't have the same representation in engine vs the DCC. In engine they'd handle Radius and Height parameters, in the DCC it's a bunch of vertices.\n\nSo the idea, for Blender, would be to leverage the geometry nodes to give the user parameters to play with (radius, height), even if the actual object in Blender is still a mesh.\n\n`Geometry Nodes` presets should be enough for now. After all, you can already generate those shapes in the `Geometry Nodes` already. What is important would be to have control, even if purely manual at import time, on how the Shape will be presented in Blender. For example, most users will want a Box to be defined with three parameters: `sizeX, sizeY, sizeZ`. However, depending of the physics engine you are dealing with, sometimes boxes are represented by two vectors: `bottom-left` and `top-right`. To match the Engine representation in the DCC, we'd need to be able to replace the default Geometry node by ours, where we'd expose the `bottom-left` / `top-right` vectors to the user.", "Blender development todo list -- Import/Export\nNOTE: this is a direct dump of Import_Export (without cherrypicking the [still] valid items)\n\n## Blender files and Library linking\n\n- [ ] Mixing \"direct\" and \"indirect\" data not well supported #26706\n- [ ] Making local data which is still used in libraries, causes problems #44321\n\n## All Formats\n\nCurrently negative scales will flip faces for formats which don't store object transformations (obj, ply, stl ... etc). #35892\n\n## FBX\nSee [[Extensions:2.6/Py/Scripts/Import-Export/Autodesk_FBX]].\n\n## Alembic\n- [ ] While Alembic exports particles as points and supports ParticleInstance modifiers it could also support particle duplication (dupliobjects etc.), see #54703\n" ]

The use of atomics in `pbvh_update_normals_accum_task_cb` to add normals from faces to vertices is problematic. Ideally those should be avoided entirely but it's not simple to do so. Possibilities:\n\n* Figure out which vertices are shared with other nodes, and only use atomics for those.\n* Store adjacency info for the entire mesh, and gather normals per vertex.\n* Store adjacent faces of all border vertices of a node, and avoid a global vertex normal array and atomics.\n* Use a vertex normal buffer per node with duplicated vertices, and somehow merge the border vertices in a second step.\n* ...?\n\nSmoothing tools may also be able to benefit from this, to work without the overhead of storing adjacency info of the entire mesh. \n\nDepending if the brush tool needs normals, we could delay updating normals outside of the viewport. \n\n## Coherent memory access\n\nEach PBVH node contains a subset of the mesh vertices and faces. These are not contiguous so iterating over all vertices in node leads to incoherent memory access.\n\nTwo things we can do here:\n* Ensure vertex and face indices in a node are at least sorted.\n* Reorder vertex and face indices in the original mesh, so that all vertices and faces unique to a node are all stored next to each other in the global mesh array. Also could be used to reduce PBVH memory usage, since not all indices need to be store then, only a range of unique vertices + indices of border vertices owned by other nodes.\n\nFor multires this is less of an issue since all vertices within a grids are in one block, though it might help a little bit to not allocate every grid individually and instead have one allocation per node.\n\n## Partial redraw\n\n* #70295 (Sculpt partial redraw not working)\n* For symmetry, the region covered by partial redraw can become arbitrarily big. We could add a test to see if one side is offscreen entirely. Other than that, we'd need to define multiple regions, which could then be used for culling the PBVH nodes. Drawing the viewport one time for each region is likely slow though, so it could be rendered at full viewport resolution but blit multiple separate regions.\n\n## Draw buffers\n\n- [x] [D5926: Sculpt: multithread GPU draw buffer filling](D5926)\n- [x] [D5922: Sculpt: only update GPU buffers of PBVH nodes inside the viewport](D5922)\n- [ ] Use `GPU_vertbuf_raw_step` to reduce overhead of creating buffers in `gpu_buffers.c` (only used in a few places now)\n- [ ] Submitting vertex buffers to the GPU has some overhead. It may be possible to do those copies asynchronously in the driver.\n\n## Masks\n\nTagging PBVH nodes as fully masked would let us skip iterating over their vertices for sculpt tools. Drawing code could also avoid storing a buffer in this case, though the overhead of allocating/freeing that often may not be worth it. \n\nTagging PBVH nodes as fully unmasked would let us quickly skip drawing them as part of the overlay.\n\nMask are currently draw in a separate pass as part of the overlays. It would be more efficient to draw then along with the original faces, so we can draw faces just once.\n\n## Consolidate vertex loops\n\nThere are various operations that loop over all vertices or faces. The sculpt brush operation, merging results for symmetry, bounding box updates, normal updates, draw buffer updates, etc.\n\nSome of these may be possible to merge together, to reduce the overhead of threading any the cost of memory access and cache misses.\n\n## Bounding box frustum tests\n\nSculpt tools that take into account the frustum only use 4 clipping planes, we should add another plane to clip nodes behind the camera. But unlike drawing, don't do use clip end and always have clip start equal to 0.\n\nFrustum - AABB intersection tests do not appear to be a bottleneck currently. But some possible optimizations here:\n* For inner nodes detected to be fully contained in the frustum, skip tests for all child nodes\n* Multithreaded tree traversal, these tests are single threaded in most cases now\n* Cache visibility of nodes per viewport\n* Use center + half size instead of min + max for storing bounding boxes\n\n## Threading\n\n- [x] It may be worth testing if the current settings for `BLI_parallel_range_settings_defaults` are still optimal. Maybe the node limit can be removed, chunk size code be reduced or increased, or scheduling could be dynamic instead of static.\n\nChanged now to remove node limit and use dynamic scheduling with chunk size 1, gave about a 10% performance improvement. For a high number of nodes it may be worth increasing the chunk size.\n\n## Symmetry\n\nFor X symmetry we currently do 2 loops over all vertices, and then do another loop to merge them. These 3 could perhaps be merged into one loop, though code might become significantly more complicated as every brush tool may need to code to handle symmetry.\n\n## Low level optimizations\n\nOverall, this kind of optimization requires carefully analyzing code that runs per mesh element, and trying to make it faster.\n\nSculpt tools support many settings, and the number of functions calls, conditionals and following of pointers adds up. It can be worth testing what happens when most of the code is removed, what kind of overhead there is.\n\nIt can help to copy some commonly used variables onto the stack functions, ensuring that they can stay in registers and avoiding pointer aliasing. Test that check multiple variables could be precomputed and the result stored in a bitflag.\n\nMore functions can be inlined in some cases. For example bmesh iterators used for dyntopo go through function pointers and function calls, while they really can be a simple double loop over chunks and the elements within the chunks.\n\n## PBVH building\n\nBuilding the PBVH is not the most performance critical since it only happens when entering sculpt mode, but there is room for optimization anyway. The most obvious one is multithreading.\n\n## Brush radius bounds\n\nCulling of nodes outside the brush radius is disabled for 2D Falloff:\n```\nbool sculpt_search_circle_cb(PBVHNode *node, void *data_v)\n{\n ...\n return dist_sq < data->radius_squared || 1;\n}\n```\n\nElastic Deform has no bounds, but it may be possible to compute some even if they are bigger than the brush radius.\n\n## Memory allocations for all vertices\n\nSome sculpt tools allocate arrays the size of all vertices for temporary data. For operations that are local, it would be better to allocate arrays per PBVH node when possible.\n\nIn some cases this might make little difference, virtual memory pages may be mapped on demand until there are actual reads/writes (though this is not obviously guaranteed for all allocators and operating systems?).\n\nAlso regarding coherent memory access, this could improve performance, if vertices are grouped per node as described above.\n\n## Undo\n\nUndo pushes all nodes that are whose bounding boxes are within the brush radius. However that doesn't mean any vertices in that node are actually affected by the brush. In a simple test painting on a sphere, it pushed e.g. 18 nodes but only actually modified 7.\n\nWe can reduce undo memory by delaying the undo push until we know any vertices within the node are about to be modified, though this may have a small performance impact. Ideally this would take into account both the brush radius test and masking/textures.\n\nSimilarly, we also sometimes call `BKE_pbvh_node_mark_redraw` or `BKE_pbvh_node_mark_normals_update` for nodes without checking if any vertices within have actually been modified.", "Cycles takes very long to cancel a render\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 431.07\n\nBroken: version: 3.2.0\nWorked: 2.93\n\nEver since Cycles was upgraded to Cycles X whenever I render a scene with a high Max sample count and cancel the render mid-render it always takes very long (up to a few minutes) until the render actually stops.\nThe time it takes to until the render stops seems to be proportional to both scene complexity and Max sample count.\nAt the start of rendering the samples first go up at small increments and later go up at greater increments.

If you examine #105324 you will see many changed files, but almost all of them can be ignored as they were just adding general support for this feature. You can add this feature to other platforms by changing two files, mostly by adding a single small function.\n\nFor Mac, for example, you can open up `intern/ghost/intern/GHOST_SystemCocoa.mm`. There is a `getCapabilities()` function that is setting flags for what a platform is capable of. You can just remove GHOST_kCapabilityDesktopSample from that list of things not supported. Then add a new function to the file, `getPixelAtCursor` that matches the others. Just ask the operating system where the mouse cursor is now, find the color at that point, and then return that as three floats (0-1) in sRGB color space. Don't forget to add a function declaration to `GHOST_SystemCocoa.hh`.\n\nLooking at detect-color-under-macos-mouse-cursor and get-the-color-a-pixel-on-the-screen-in-objective-c-cocoa-app this appears to need just a handful of lines.\n\n", "Glare Node set to \"Fog Glow\" in Real-Time Compositor vastly different from actual render results\nOperating system: Windows 10\nGraphics card: RTX3070 FE\n\nBroken: 3.6 A\nWorked: N/A\n\nWhen using the Glare Node in Real-Time compositor, the results in the viewport are turned up way higher than the actual render and Backdrop preview.\n\n\n\n1.

And do-version code there should be smart enough to check when it runs on the local main, or a lib main, and adapt its code accordingly.\n\n~~Another thing to fix is in `BKE_libblock_alloc`, which should assign `main->curlib` to the newly created ID's `id->lib` (and tag it as indirectly linked). That way if doversion needs to create an ID in a library context, that new ID is properly created as a 'virtual' indirectly linked data, and does not break Main consistency (even if doing stupid things like generating default brushes for a lib main).~~ Done in 7681326acd", "History filled with \"Double click to rename\" when user changed index of a UIList\n\n\nBroken: version: 3.2.0\nWorked: Never\n\n- open Blender\n- add particle systems\n- change particle systems index\n- see how your history got vanished by useless flags\n\nGifs: \n\n\nI believe in order to fix this bug,\na `SKIP_UNDO` flag need to be implemented at a property level \nexample: \n`my_uilist_idx : bpy.props.IntProperty(options={'SKIP_UNDO'},)`\n\nThis issue is not only linked with UILists indexes, but also with any properties used strictly GUI\n\nsee the blender dev thread where we talk about the general issue of using properties for interface\n4\n\n\n\n", "Datablocks can't be duplicated everywhere, because trick with fake user no longer works\nOperating system: Windows-10-10.0.17134 64 Bits\nGraphics card: Intel(R) HD Graphics 4600 Intel 4.3.0 - Build 20.19.15.4454\n\n\nBroken: version: 2.80 (sub 72)\nWorked: (optional) 2.79b\n\n\nThe MCE or tracker, should allow you to duplicate the clip asset so that you can attach other tracker bundles.

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.

[ "Sculpt Mode Multires Design\nThe purpose of this task is to describe the main uses cases and functionality that should be provided by a Multires sculpting system, as well as to discuss a plan on how to implement that in Blender.\n\n\n## The main use case of Multires\n\n### The problem Multires solves\n\nWhen you are working on any art medium (this also applies for painting), you should always try to work from the general shapes to the details. In case of digital sculpting, this means that you should always try to work with the minimum number of vertices that represent the level of detail you are trying to add to the model.\nThis is also true for the current workflow we have implemented (The Voxel remesher). By default, it provides a low poly mesh (about 10K vertices), that you should deform trying to get main shape of the object you want. After that, you increase the resolution of the remesher until you have enough vertices to represent the next level of detail you want to work on, and you continue from there.\nThe reasons you want to work this way are:\n\n- Performance: It is faster (more responsive, without lag) to deform a mesh with 10K vertices than a mesh with 25M vertices. If you use a big brush size needed to modify the object proportions on 25M vertices at the same time, it is going to lag. (Unrelated note, but we should not try to optimize Sculpt Mode to support these kind of operations as they don’t make any sense with a Multires system in place).\n\n- (Most important) Noise: If you sculpt with more vertices than needed for the size of details and shapes you are trying to get, you are going to end with a lot of uncontrolled shape noise produced by the tools. This is not a specific problem with Blender brushes and tools, this happens in any software and in every sculpting system. If you use the Draw brush to add some volume on a big area directly onto a 25M vertices mesh, you are going to need need to clean manually all small uncontrolled imperfections that big stroke stroke produced if you want that to be the final surface. If you start sculpting from a sphere with 1M vertices, you are going to spend more time cleaning shape noise than sculpting or the sculpt is just going to look bad. This is why nobody works this way. You don’t generate unintended shape noise if there aren’t enough vertices to represent it.\n\n\nThat is the main problem Multires sculpting solves. With Multires, you are able to choose at any moment the level of detail that is appropriate for the change you want to make in you model, solving both the performance and the noise issues. This gives an artist a huge amount of freedom as you know you can always go back to tweak low frequency details (proportions, general volumes) after sculpting mid/high frequency details (wrinkles, skin alphas...) if you consider that they don’t look right, without loosing any work.\n\nWithout this, the rest of the sculpting workflows (the Voxel remesher, Dyntopo) are the same as sculpting with real clay or marble, you can only sculpt bigger first shapes, then mid details and them the small details. If it does not look right, there is not way to fix it, you need to delete what looks wrong and start again. This is why those workflows are often used for concepting general shapes, and you want two switch to Multires as soon as you can. Sculpting a complex model without using Multires, on any software, is extremely (and unnecessarily) hard and it requires an insane amount of skill from the artist to workaround the limitation. It is like sculpting without using undo. It is too risky to create a high poly sculpt with projected alphas without this feature.\n\nIn order to solve this problem, the main thing Multires needs to guarantee is that when you sculpt shapes on your model in the appropriate resolution level, all the other levels are updated accordingly to reflect the changes you did. This is what people often refer as ¨detail propagation¨.\n\n### Multires Design\n\nWhen designing a sculpting Multires system that provides the previously mentioned functionality, We need to take the following points into consideration:\n\n1. All Multires subdivision levels contain valid information (sculpted shapes, mask, colors...) that should never be lost or damaged. \n\n2. The user wants to modify any subdivision level, at any time, without restrictions (there should not be limits of how much the mesh should be deformed or “not allowed modifications”).\n\n3. The user wants to delete and rebuild higher/lower subdivision levels in he/she considers that the shape information that level contains is not longer relevant. \n\nFor example, if the user wants to do a high poly sculpt, he/she switches to the higher level subdivision possible that the computer allows to create the high frequency detail projecting alphas. When that is done, the user may want to switch to a lower level to tweak proportions, or to a mid level to tweak small volumes with a soft brush. All the work the user put into applying the alphas should be propagated with the lower subdivision level changes with the Multires functionality and the model should look fine.\n\nIf, for some reason (a bug or an design issue in the implementation that did not consider point 1), switching and modifying lower levels may introduce mesh artifacts in the higher ones (the ones that contains the alpha projections and high frequency details), it will destroy all the work done previously by the user in that levels. \n\nIn that case, the user is again limited to not going back to select the mesh resolution needed for the modifications he/she wants to make in the mesh. A Multires system like this is not solving the intended problem and there is no reason to use it. It provides the same functionality as any of the other sculpting workflows (Voxel, Dyntopo), but even more limited as the user can’t modify the base topology to adapt it to a new shape. It does not have any reason to exist.\n\nIf you project requires you to use a fixed predefined topology in your model (for animation, for example), subdividing the mesh manually and deforming it with a cage or a datatransfer provides the same functionality. You can also get a lower subdivision level by duplicating the model and using unsubdivide if you need it for texture baking or animation. This is not the main problem Multires should be trying to solve.\n\n \n**Any unwanted mesh artifact in the detail propagation, no matter how small it is, invalidates all Multires sculpting features and makes it not functional for its intended use case, as it leads to irreparable data corruption.**\n \n\n### Current Multires Modifier\n\nConsidering the previously design and use case description as valid Multires sculpting system:\n\n1. Multires in 2.81 does not support switching levels. This invalidates the feature completely and makes it not functional, but prevents the users to corrupt the mesh data if they use it. This is like not having Multires sculpting at all.\n2. Multires in 2.80 creates artifacts and vertex explosions when modifying any level, creating irreparable mesh data corruption. Releasing Blender with Multires in this state and without any visible UI warning could have destroyed the projects of many users in an irreparable way. Luckily, most users were not using it to create their models in the previous versions because it was also not working as intended. \n3. Multires in 2.79 and before creates a visible grid pattern on higher levels when modifying lower ones. This introduces unwanted shape noise and effectively destroys valid sculpted information, making it not functional for its intended use case. Users are limited to work considering of how much they can deform lower levels by the amount of noise they are predicting Multires will produce in the higher ones. This is not something that should be happening in a production ready implementation of the feature.\n\nThe most advances tools Blender has right now that were added in the last releases (Quadriflow, Elastic deform, IK Pose brush...) are designed to work with a Multires system:\n\n- The main purpose of Quadriflow is to produce subdividable geometry for a Multires. When you are done sculpting with Dyntopo/Voxel remesher, where you can’t have the freedom to choose the level of detail you want to work on, you can quickly generate a base mesh, subdivide it and reproject the details back. That way you can tweak again general proportions and low frequency detail.\n\n- These brush tools are designed to tweak proportions/big shapes of models, which is something you most likely want to do after sculpting more detail to have an idea of how your model looks like. Multires solves that problem.\n\n- These brushes can’t be used directly on high poly meshes. These tools needs to have disabled some sculpt mode optimizations in order to work, so they are much slower than regular brushes. In fact, if you try to use the IK pose brush directly on a high poly mesh, most likely you are going to run out of memory. If you don’t, it is going to create terrible artifacts between each segment. In order for these brushes to work as intended on high poly meshes, you need to use Multires to switch to a lower level, use the brush, and then switch to a higher level again to get the intended result.\n\n## Multires implementation reference\n\nSculptGL contains a valid and functional Multires sculpting implementation. You can try it by sculpting different details at different levels and switching between them, as well as creating and deleting subdivision levels:\n\nsculptgl/\n\nThis implementation of Multires provides:\n\n- Detail propagation that works across all levels. You can choose the desired level you want to sculpt on and that deformation is propagated correctly to all subdivision levels. There are not visible artifacts of any kind.\n\n- You can both create and delete levels in both directions (higher levels and lower levels) with subdivide/delete higher and reverse/delete lower. \n\nThese features are the minimum and required a Multires implementation in Blender should provide, as they are pretty much the definition of a Multires sculpting system. Any other Multires related feature or optimization (being part of the modifier stack, baking, shape keys, layers, exporting, reprojection, tool compatibility, Quadriflow...) should always come later. There should not be a design decisions that prioritize any other Multires feature or optimization without having those minimums perfectly working, bug free and functional.\n\n\n## Proposal\n\nGiven the fact that, as described here, Multires was never a functional feature for its intended purpose and:\n\n- The code is extremely hard to read and maintain. I still can’t understand what it is doing in some places or what was the reasoning to make it work that way in the first place. \n- New features are planned that require Multires support (masking tools, vertex colors, visibility operators). Adding Multires support for those features should not be a project bigger than the feature itself. This was the case with most of the 2.81 tools, and probably with the future planned features (Sculpt vertex colors or visibility management, for example)\n- We already have and sculpt tools abstraction layer in place. Making changes on the underlying data structures of sculpt mode should be easier than before\n- The original Multires comes from before 2.5. The basics of how it should works were never correct and a lot of features and modifications were added during the years. We are now trying to build state of the art sculpting features on top of a broken foundation that has more than 10 years. \n\nSome options are:\n\n\t- Replace Multires modifier with a simple implementation based on the SculptGL code (something we know it works) and start again from there. We can keep the current Multires modifier for compatibility, but we need to evaluate if supporting the features and fixes described in this task on the current code (and make it work exactly as the SculptGL Multires) is going to take more time than implementing something based on the SculptGL code from scratch. We also need to look that the new features that are planned and evaluate how hard they are going to be to add to the current Multires code (colors, per face data...) knowing that the SculptGL implementation already supports them.\n\t\n\t- Try to add this functionality to the current Multires modifier. In that case, the priority should always be supporting the functionality described in this task first, and the bring all the rest of the features back. In that case, it would be needed better documentation and code organization to be able to integrate new features into it easily.

We shouldn't add any more smoothing brushes unless really necessary.\n\n# Proposal:\n\nA possible solution for this would be to make the smoothing strength a brush setting for every brush.\nThis would have the following advantages:\n\n- We could add a shortcut operator on `Alt F` to control the smoothing strength of the currently active brush.

The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "Backfacing wireframes show gaps in Edit Mode\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.48\n\nBroken: version: 2.83.1\n\nIn Edit Mode backfacing wireframes are sometimes hardly or not visible. This is especially noticeable when an edge loop is selected (see attached video). It seems as if they are covered by edges that are actually behind them. Maybe I'm missing something, but I've played with a lot of settings.\n\n[Blender Wireframe Gaps 01-1.m4v](Blender_Wireframe_Gaps_01-1.m4v)\n\n", "Sculpt Mode Gesture Tools\nThis task keeps track of the missing gesture tools in Sculpt Mode\n\n| | Box | Lasso | Line | PolyLine |\n|------------|-----------|-----------|-------|----------|\n| Mask | In master | In master | In master | |\n| Hide | In master | | | |\n| Face Set | In master | In master | | |\n| Color Fill | | | | |\n| Trim | In master | In master | | |\n| Project | | | In master | |\n\n**Gesture Tools**\n**Mask**: Performs a masking operation in the area affected by the gesture. It can mask, unmask or invert the mask.\n**Hide**: Hides the vertices affected by the gesture without modifying the face sets.\n**Face Set**: Creates a new Face Set that contains all vertices affected by the gesture\n**Color fill**: Fills the area affected by the gesture with color, using a blend mode and a strength.\n**Trim**: Cuts the area affected by the gesture using a boolean operation. This modifies the mesh topology and needs to use the boolean solver. It creates a new Face Set for the new created faces after the boolean cut.\n**Project**: Projects the vertices outside/inside the area of the gesture towards the area of the gesture. This allows to simulate cuts in the mesh without modifying the topology, so it should be much faster in cases were a remesh operation will follow the cut operation. Unlike trimming, this operation won't be able to make hole though the mesh. \n\n**Polyline**\nPolyline is not implemented yet as a gesture in ##wm##. It will use the same data as the lasso gesture, but it will add a point on each mouse click and it will confirm the gesture with enter. This won't require any modification to the code of any gesture tool (sharing they same code with the lasso gesture will work). \n\n**Additional tasks**\n- Option to snap the line/polyline gesture angle\n- Improve the line gesture preview, displaying which side of the line/plane is going to be affected", "Mask brush stops working in tiling sculpting mode after changing its size through \"F\" hotkey\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.59\n\nBroken: version: 2.93, 3.3.0\nWorked: -\n\nWhen an object has the Multires modifier, mask brush stops working in tiling sculpting mode after.

It should be truncated so that it displays only the top few recent folders (i.e. the other folders, the little disclosure triangle and the section's bottom drag bar shouldn't be visible).\n4. Hover the cursor over the File Dialog and move it outside of the dialog, making sure you exit the dialog through the bottom part of the \"Recent\" section.\n5. Watch as the \"Active Recent Folder\" tooltip gets triggered/displayed while the mouse cursor is outside of the dialog. This shouldn't happen!\n6. Now enlarge the bottom part of the File Dialog, so that the \"Recent\" section is no longer truncated and fully displayed (including its disclosure triangle and drag bar).\n7. Repeat step 4 and notice the tooltip doesn't get triggered anymore! This is the desired behavior.\n8. Resize the bottom part of the File Dialog so that the \"Recent\" section is again truncated, but this time don't truncate its bottom part (i.e. the disclosure triangle should be visible).\n9. Repeat step 4 and notice the tooltip again doesn't get triggered anymore! This is again the desired behavior.\n\n\n\n**Conclusion**\nIt looks like the the File dialog somehow doesn't properly detect the mouse has exited the dialog when it exits directly from a section's contents, thereby not crossing over the section's border/other UI parts.\n\nI hope this makes some sense ;-)\n" ]

This works if you move your cursor to an item, or to an empty area. But, if you don't move the cursor at all, this doesn't work. This makes the behaviour inconsistent, and makes the pies 'stick' in an annoying way if you regret opening one.\n\n## Letter Input While Pie is Active\nWhile number input works reasonably well, in Blender we also use letters to invoke options in menus. For pies, letters work better, because the order makes less direct sense. There's nothing intuitive that says left=1, right=2, and so on. We should enable letter input to activate pie options. This way, user can press Z, S to activate Solid Mode.\n\n----\n\nThese three changes should make pie menus more delightful to use.", "Alt-Drag (multi-editing) fails for HSV color buttons\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.28\n\nBroken: version: 2.83 (sub 1)\nSeems to be a long-lasting issue, as even Blender 2.81a shows the same behaviour.\n\nPretty much the title. \nTrying to assign an object color through the Object Properties tab (Viewport Display > Color) to multiple Objects doesn't work, neither by picking the Color on the Color Wheel, nor by moving the HSV sliders, while Alt-Clicking.

Everyone is welcome to join the discussion by proposing more ideas or solutions, by creating mockups or by just giving some own input.\n\n----\n\n# Scope of Widgets\n\n### Description\n\nWhen should a tool use a widget?\n\nExamples:\n\n* Edit Mesh Spin Tool\n* Edit Mesh Smooth tool (number of steps, smooth factor)\n* Edit Mesh Bevel/Inset\n* Edit Mesh UV Rotate\n* Edit Mesh Subdivide\n\nSpin tool is an example where widgets make a lot of sense (you rotate around an axis, so direct manipulation is useful).\n\nThe issue with Smooth & UV-Rotate is that using a 3D manipulator for these is using manipulator simply as a way to access buttons in the view-port.\n\nAn issue with bevel/inset depends on the kind of manipulator used. Having a single manipulator in the view doesn't directly relate to the edge, and again - its more a replacement for accessing buttons in the tool-bar.\n\n### Proposed Solutions\n\nSuggest not to use manipulators if they are simply an alternate access to buttons.\n\nAs for bevel/inset: we could make the bevel edges themselves into manipulators, so you could click on beveled edge and drag it.\n\n----\n\n# Toggling Visibility of Widgets\n\n### Description\n\nCurrently, only the widgets of the active object are drawn. While this works for most cases, being able to precisely control which widgets are visible and which not can be useful.\nFor example, in future, a camera could have widgets for the focal length, sensor size, depth of field distance, ... If all are visible all the time it's easy to accidentally manipulate them.\n\n### Proposed Solutions\n\n* Draw a panel for the active object in which its widgets can be enabled/disabled individually (similar to \"Display\" for cameras).\n* Add a toggle button next to every button represented by a widget (similar to how it's done in the transform panel in the properties region, where you can press the 'lock' icon to disable the widget for this axis)\n\n### Open Topics\n\n* Where would the manipulator toggles be stored? (Object / Viewport / Tool-Settings)\n* How to expose settings that aren't related directly to objects? (Group Center, View-Port Clipping Bounds)\n\n----\n\n# Numerical Input\n\n### Description\n\nIt should be possible for users to input precise values to manipulate a widget (and thus the value it represents). This way they can keep their locus of attention in the viewport, avoiding having to search for a button in the UI.\n\n### Proposed Solutions\n\n* Enabling number input by holding a modifier key while clicking on widget (as in - Ctrl+LMB on widget activates modal mode to input value)\n\n---\n\n# Snap System\n\nUsers may want to snap manipulators to other elements in the scene, eg:\n\n* Snapping the spin center-point to a vertex on a mesh.\n* Snapping bisect angle to a vertex\n* Snapping the camera's DOF to the surface of an object.\n\nNote that currently holding Ctrl sets `WM_MANIPULATOR_TWEAK_SNAP` but each manipulator needs to implement this.\n\n### Proposed Solutions\n\n* Each manipulator has a snap flag for 'TRANSLATE | ROTATE | SCALE', when set, holding Ctrl will snap to any of the elements set.\n* Snapping can also respect scene settings (in the 3D) view-port, so users can snap as with mesh edit-mode.\n\n----\n\n# Key Framing\n\nWhen the cursor is over a manipulator, do we want to support I-Key to keyframe that setting (DOF, lense for eg).\n\n----\n\n# Theme Colors\n\nManipulators now use theme colors, there are basic preset colors to use: (HIGHLIGHT, PRIMARY, SECONDARY, A, B).\n\nWhere A/B are for other controls.\n\n*Currently they're hard coded in manipulators but they can be set however we like.*", "UV space aware triangulation\nPlease see #102683 for details, since the issue is described and discussed there.

Works on RTX 3080 graphics card with driver 497.29 on all blender versions\n\nAt times while working in the blender program, I encounter absurdly long render times for one frame: oB4BJ5L.png (shreenshot).\n\nI ran render tests on different driver versions (527.56, 522.30, 526.86, 497.29). In all versions of the drivers, after some time, performance dropped hundreds of times, except for driver 497.29. It works stably. Also tests were carried out on blender versions 3.3, 3.4, 3.4.1.\n\nIt would seem that the problem is solved, you can simply install the 497.29 driver and work stably on it, but this is not so. Only blender works on this driver version, other programs crash and require drivers of at least 520. Regardless of the driver version, the video card is always loaded at 100%\n\nI've done some testing and may have found what's wrong. I made a scene with several cubes, a volume and a strong light source, and also set a large sample size.\nResults:\n497.29 driver - 4 minutes 12 seconds (806 MB of video memory used)\n527.56 driver - 3 minutes 45 seconds (806 MB of video memory used)\nAt the same time, the viewport works quickly and responsively in the cycles render mode. Just like I planned\nI also ran a test with a complex scene and then everything got much worse:\n497.29 driver - 22 minutes 51 seconds (8775 MB VRAM used)\n527.56 driver - 35 minutes 37 seconds (8775 MB of video memory used)\nThe viewport is quite buggy and poorly responsive in both versions of the drivers (but this is logical since the scene is complex). In the viewport, the view mode in cycles on the 497.29 driver works as expected - it gradually develops the picture. On the 527.56 driver, cycles almost doesn't work in the cycles view mode (more precisely, it works, but it's even slower than my four-core processor).\nIn render mode 527.56 the driver is unstable. I had to wait 11 minutes for the first sample to load. And I'm still lucky. Sometimes the render time can be 44 hours for a single frame (oB4BJ5L.png)\n\nAs a result, we can come to the conclusion that with the new drivers, the blender is unstable when the video memory is almost completely loaded.\n\nI recorded the workflow of all tests on video in an accelerated version: 1_oMmj90PLXiojBbORk8W1ynpdzITi6gJ?usp=share_link .
