Short-term goals

Patch Review & Decision Time

  • Shaping and prioritising of work on Animation 2025 Opportunity Solution Tree (OST).
    • Sybren: the order in which we do work is relevant, maybe things like Rig Explainer should be done after building, say, a new Armature system?
    • Marion: Rig Explainer could aid in creation / debugging of such a new armature system, so having it beforehand could be a good investment.
    • Amélie: What about Grease Pencil (GP)? Can we avoid more if-GP-switches in the code? Also from the artists’ point of view, keying is conceptually quite different when animating in 3D or in 2D/GP. Not directly something for in the OST, but still good to keep in mind.
    • Sybren flagged some opportunities in the OST as “interesting to start with”, and asks the module to cast their votes on what they would prioritise.
    • Most voted were the Bone Picker, Rig Profiler, Mesh Ghosting, improving mesh deformation speed (CPU-to-GPU traffic). With a note from Demeter that the animators at Blender Studio really want to have a bone picker.
  • T103074: Armature Modifier: Multi Modifier changes the meaning of the mask vertex group
    • Module agrees this is buggy
    • Likely rare that this is set from Python. Might be used in some rig generator script, but this is not known to the people present.
  • Marion: asks about situation where a single F-Curve gets multiple keyed values on the same frame.
    • Sybren: this is always considered a bug, please report it as such.
