notes

name-mapped retarget · rotation-only with hip translation. best results when both rigs share the same rest pose (t-pose preferred) and limb count. no ik · feet may skate when proportions differ significantly · adjust hip scale to compensate. fingers and twist bones outside the canonical joint set ride along untouched from the target's rest pose.

input · binary fbx · glb · gltf (drop the .gltf with its .bin and textures together) · dae / collada · bvh as source only. ascii fbx is rejected — re-export as binary. obj · stl · 3mf carry no skeleton.

output · glb and zipped gltf preserve the retargeted skeleton animation. usdz · obj · stl · ply are available as save targets for mesh handoff, but they do not preserve or preview the retargeted animation in this browser stack. fbx / usd / dae output are not offered because this app does not have reliable browser exporters for those formats.
