Short-term goals / Ongoing Work
- High prio bugs:
- #110946: Normalize Vertex Groups while Armature modifier is hidden: Nate has a fix.
- #111553: Blender 4.0.0 - Armature Rig with IK broken: Christoph looking into it.
- Christoph: #111263: Anim: Bake Channel operator
- Delayed to Blender 4.1 due to performance issues.
- Is a general issue with adding keys, he’s going to look at that too.
- Sybren added #112710: Bone Collections: UI Improvements, with backward-compatible changes for Blender 4.1.
- Sybren did some digging into the history of visual keying.
- Discussion about bone colors, bone collections, and the loss of bone groups for managing colors. Blender Studio animators (Rik, Hjalti, Pablo), Nathan, and Sybren.
- The new bone collection system needs a better way to manage bone colors.
- This might become an add-on for now, to be able to quickly test & iterate on ideas.
- #112850: Butterworth Filter is causing issues on geometry
- Christoph: likely has to do with interpolation of quaternions & how Cycles interpolates them. It has more to do with quaternion values themselves than animation.
- Alexander: might have to do with quaternion flipping.
- Christoph: smoothing is done per channel, so how we handle those is iffy.
- Sybren: maybe we want some ‘quaternion normalisation’ filter that we can run after the smoothing (or as separate operator).
- Nathan: there is a related discussion on devtalk. He’s sceptical it’s directly causing this issue, though.
Patch Review & Decision Time
- #112943: Proposal: Unify Active/Selected Bone Colors and set current Blender Theme Colors as Default
- Ivan: Part of the issue is already fixed by Demeter’s proposal because it simply has beter colors.
- Some unclarity over the use cases that are to be supported by this proposal.
Pose Library / Asset Shelf demo
Julian demonstrated the new Asset Shelf system.
- Sybren: trim start of name instead of begin? Julian: doable, and you can also give assets a “UI name” now that overrules the datablock name.
- Felipe: possible to have the asset shelf in a non-3D Viewport editor? Julian: not at the moment, but adding it to other editors is not too hard. Just needs some C++ code.
- Sybren: Move blend slider into “the notch”? Julian: has some issues when it gets too narrow, but we could do something like that & extend the shelf to accomodate smaller areas. Will be up to the Anim & Rigging module to do, though.
- Sybren: what if there is not enough space for all the catalogs? Julian: you can scroll like any other header.
Help Needed
Demeter wants rigger & animator feedback on:
- #112635: Proposal: New Bone Color Presets
- Two Parenting UX proposals: #112758: Object Parenting and #112760: Bone Parenting
Next Meeting
The next meeting will be on Thursday 2023-10-05T16:00:00Z. Again it will be open for everybody who’s interested. The provisionary meeting agenda will be linked in the #animation-module channel before the meeting.
