VAST-AI-Research/SkinTokens — reverse-engineered prompt

Build me a simple local tool for automatic 3D character rigging using SkinTokens and TokenRig. I want to upload a GLB mesh in the browser, click one button, and get back a rigged GLB with a generated skeleton and skin weights that I can open in Blender or another 3D tool.

Please make the setup smooth. It should check for the needed pretrained models and download them if they’re missing, then start a small web demo locally. Also keep a command line option so I can rig one file or a whole folder of meshes. Include options to preserve the original texture and scale, use an existing skeleton if the model already has one, and apply the optional post processing.

Assume I have an NVIDIA GPU machine for inference. Make the README clear enough for someone like me to install it, run the demo, and understand where the finished files are saved. Look up current docs online if you need to.
