  CATS Blender Plugin 5.2.3.2

  This is another smaller maintenance release focused on improving Fix Model performance, cleaning up some old internal code, and fixing a handful of issues affecting rigidbodies, visemes, and eye tracking.

  Fixed

  • Fixed Fix Model failing to remove rigidbody and joint groups when their names used different capitalisation, such as Rigidbodies or Joints.
  • Fixed the rigidbody/joint detection condition so the duplicate guard is applied correctly.
  • Fixed Auto Visemes silently skipping viseme creation on a second run.
    • The old VisemeCache stored generated vertex data but never applied it, so cache hits skipped mix_shapekey and created no new keys.
    • The unused cache has now been removed.
  • Fixed eye positioning crashing when the centre of an eye vertex group could not be calculated.
    • fix_eye_position now reports failure cleanly instead of allowing a None value to reach the coordinate logic.
    • Both callers now clean up stray eye bones, restore state, and report the problem instead of crashing.

  Improved

  • Improved bone lookup performance during Fix Model.

    • Replaced the unused BoneCache with a working EditBoneIndex.
    • The three bone rename passes now use indexed lookups instead of repeatedly scanning every edit bone.
    • This reduces Fix Model time by around 26% on a 1000-bone armature, with identical output.

  • Improved vertex-group lookup performance during Fix Model's weight merge passes.

    • Vertex groups are now indexed instead of scanning the entire collection for every candidate name.
    • The index rebuilds only when groups are added or removed.
    • In testing on a 1019-bone model, this reduced the relevant Fix Model time from around 1.19s to 0.56s, with identical weights.

  Changed

  • Updated the repository URL to the new repository location.
  • Moved rigidbody and joint detection into the shared Common.is_rigidbody_or_joint helper instead of duplicating the logic.

  Tests

  • Added tests covering the removed VisemeCache behaviour.
  • Added regression coverage for eye-position failure handling.

  Internal Cleanup

  • Removed the old unused BoneCache implementation.
  • Removed the dead VisemeCache.
  • Centralised rigidbody and joint name detection into the shared Common.is_rigidbody_or_joint helper.
