skintokens-auto-rigging

Run the skin-tokens.cpp CLI rig command with the F16 GGUF model directory, your input GLB, and an output path, optionally with --postprocess for smoother weights. The output GLB imports into Godot 4 as Skeleton3D plus a skinned MeshInstance3D.

Use the skin command with the mesh GLB and a skeleton GLB, choosing a fit mode: global for differing coordinates, none when coordinates match, or articulated for experimental humanoid arm alignment. The tool computes learned weights without touching the existing skeleton.

Yes, the C++ port runs on CPU or Vulkan, unlike the upstream Python repo which requires an NVIDIA GPU with at least 14 GB of memory. CPU is slower but fully supported, and Vulkan offers slightly looser numerics.

The rig command is explicitly experimental and can produce unsuitable bone topologies, so an artist should review skeletons before animating. Results are strongest on humanoid-like shapes, and generation takes several minutes per mesh.

Warping happens when the supplied skeleton pose does not match the mesh coordinates. Use --fit global to align bind pose with the mesh, or --fit articulated for humanoid arms; reserve --fit none for files already sharing coordinates.
