"""rename_clip.py — rename the animation inside a GLB (for dance-code adoption).
|
||
|
|
|
||
|
|
Used when a provisional dance (nd##) is adopted and gets its final dance code
|
||
|
|
(see docs/dances/REGISTRY.md). Renames the clip baked into the GLB; the pack
|
||
|
|
rename is just the output filename.
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
blender --background --python tools/rename_clip.py -- \
|
||
|
|
--src <in.glb> --out <out.glb> --name <NewClipName>
