Fix: Use smplx2fbx.py directly with zero beta (20-dim, fixed dimension mismatch)

Fix: Euler angle convention sxyz (was rxyz), ground alignment (min vertex Y=0)

SMPLH FBX: body-only (22 joints), hand joints zeroed out

Re-upload with SMPLX model FBX (was SMPLH, now matches motion data format)

Re-upload with fixed bind pose (complete parent chain) to fix waist mesh tearing

Upload teaser demo FBX, NPZ, and JSON files
