Adds 8 scripts to tooling/ for the Sprint 28 character asset pipeline: - blender_segment_body.py: segments a FullBody GLTF into 18 body-part GLBs using BMesh vertex-weight selection + 1-ring boundary expansion - blender_process_bodies.py: batch driver for all 11 body types (6 direct + 5 auto-scaled forks: thin, heavy, child) - blender_process_heads.py: processes 4 OnlyHead .blend files into GLBs + 1024x1024 solid-white mask PNGs (D-159, D-160) - blender_process_hair.py: converts 20 GLTF hairstyle/eyebrow exports to accessory GLBs + mask PNGs, creates bald.glb placeholder - blender_inspect_body.py: diagnostic — lists mesh objects + vertex counts - blender_inspect_vgroups.py: diagnostic — lists vertex groups on skinned mesh - glb_strip_utility_nodes.py: post-process GLBs to strip utility nodes (Icosphere, WGT-*, DEF-*, ORG-* meshes) from the GLTF scene graph - check_icosphere.py: diagnostic — reads GLB JSON chunk to verify node list All Blender scripts require flatpak Blender via tooling/blender wrapper. Scripts must live in project directories (flatpak sandbox blocks /tmp/). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
