## Opening

- Please **raise your hand when you don't understand** things for any reason. The purpose of these meetings is collaboration. It is absolutely fine to ask for explanations.
- There are **no recordings** of the meeting. This way everybody is free to say or show anything they want.

## Ongoing Work

[weekly-c]: https://projects.blender.org/ChrisLend/.profile/src/branch/main/reports/2024.md
[weekly-n]: https://projects.blender.org/nathanvegdahl/.profile/src/branch/main/reports/2024.md
[weekly-s]: https://projects.blender.org/dr.sybren/.profile/src/branch/main/reports/2024.md
[highprio]: https://projects.blender.org/blender/blender/issues?q=&type=all&sort=&state=open&labels=268%2c285&milestone=0&project=0&assignee=0&poster=0

- [High Prio][highprio] bugs: None!
- Christoph:
- [Christoph's weekly report][weekly-c]
- Working on Bugfixes for 4.4
- Looking at what happens when you play animation with "Sync to Audio", and during playback change the frame rate.
- Sybren: make sure to check with Sebastian Parborg, he's also looking into sync-related things.
- Nathan:
- [Nathan's weekly report][weekly-n]
- Working on [Project Setup](https://projects.blender.org/blender/blender/issues/133001) (not actually animation related). Currently the "Blender Variables" milestone.
- Sybren:
- [Sybren's weekly report][weekly-s]
- Python API docs: [#134683: Anim: update Action RNA descriptions to clarify legacy status](https://projects.blender.org/blender/blender/pulls/134683)
- Convenience for F-Curve creation: [#134686: Anim: add RNA function Action.fcurve_ensure_for_datablock(...)](https://projects.blender.org/blender/blender/pulls/134686) (basically for fixing VSE code in [#134656](https://projects.blender.org/blender/blender/pulls/134656))
- Going to investigate options to get "Z-axis along the bone" for Blender 5.0.
- Single flag on the armature, to flip between current system and desired one
- One choice for +/- X/Y/Z axis along the bone.
- Two choices, for axis along the bone and "secondary" axis.
- Nathan: probably best to use a single flag on the armature, to avoid all kinds of tooling around bones to become harder to write. Per-bone changes can be handled when importing/exporting.
- Christoph agrees with Nathan.
- Sybren: expects to end up with the single flag, modeled as an enum with two options (so it's clearer what is what than just true/false).

## Patches: Review & Decision Time

- [#134503: Improvements to bones "Select Child/Parent" hierarchy](https://projects.blender.org/blender/blender/pulls/134503)
- To decide: What happens at the end of the chain? Should the bone stay selected, or should it get deselected?
- Rik: it should keep the current selection.
- Rik: does Blender have a "select sibling" option?
- Sybren: nope.
- Rik: then selecting all children may not always be desirable.
- Rik is going to try out [the test build](https://builder.blender.org/download/patch/PR134503/) & report back on the PR.

## Rik: Slotted Actions

Rik shows a bug:

1. Character is keyed
2. All keys are deleted
3. The slot's summary line still shows keys, which are not editable.

- Nathan: what happens when you save & reload?
- Rik: the phantom keys are still there.

## Next Meeting

The next meeting will be on [date=2025-02-27 time=18:00:00 timezone="Europe/Amsterdam"]. Again it will be open for everybody who’s interested. The [provisionary meeting agenda][draft] will be updated before the meeting.
