Character: Quaternius, Universal Animation Library 2 Standard Female Mannequin.
https://quaternius.com/packs/universalanimationlibrary2.html
character-static.fbx is the original Mannequin_F.fbx, renamed only.
avatar.vrm and the animated FBX use the site's admitted UAL2 character:
original mesh/proportions/materials retained, canonical humanoid names added,
source animations excluded. VRM/FBX conversion by 3D Retarget Online.

BVH case character: Quaternius, Universal Animation Library Standard Mannequin.
https://quaternius.com/packs/universalanimationlibrary.html
avatar-ual1.glb is the site's admitted UAL1 rigged GLB reference;
original mesh/proportions/materials retained, canonical humanoid names added,
source animations excluded. It is separate from the BVH motion, not its output.

Motion: Quaternius, Universal Animation Library, Dance and Walk clips.

Canonical normalization, BVH, VRMA and motion-only FBX conversion by
3D Retarget Online. The animated FBX binds the canonical motion to the
UAL2 target's own rest skeleton. These are not Adobe Mixamo assets.

walk-travel.bvh preserves the canonical Walk root travel. Both BVH files share
a constant vertical rebase that places the minimum hips offset at zero while
preserving the original vertical range. walk-in-place.bvh then sets only
horizontal canonical hips translation to zero before the same BVH export;
vertical motion, timing and rotations are preserved. The same in-place
BVH is included in both BVH bundles. These are diagnostic variants, not a
general-purpose foot-sliding correction.
