- pipeline/strip_skin.py: with-skin Mixamo FBX -> anim-only, normalises numbered bone namespaces (mixamorigN: -> mixamorig:) - render_moves.py --self-anim renders actions baked into the char file (MIRPAMO retarget output) - phrtt2-nsfw + daphne rigged via MIRPAMO autorig (clean weights); 17-clip kit retargeted but pose quality poor — retarget stage needs a bonemap/markers tuning pass before these ship as fighters Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Blender headless: convert with-skin Mixamo FBX clips to anim-only FBX
|
|
# (deletes meshes, keeps armature+action). MIRPAMO's retarget mapper needs
|
|
# anim-only sources.
|
|
#
|
|
# Usage: Blender -b --python pipeline/strip_skin.py -- --clips "a.fbx,b.fbx" --out dir
