Convert vertex-colored meshes to UV-mapped textures with InstantTexture and xatlas

AI Impact Summary

The workflow converts vertex-colored .obj meshes into UV-mapped textures by loading the mesh with trimesh, generating a UV atlas with xatlas, remapping vertices/colors, and building a 1024x1024 texture buffer with a basic barycentric interpolation before applying a textured PBRMaterial. It relies on the InstantTexture library for the conversion scaffold and uses numpy, Pillow, OpenCV, and httpx to support texture creation and image processing; a quick start is provided via a one-liner using Converter. Limitations include holes/artifacts in the initial texture, requiring inpainting, filtering, and downsampling for production-grade results; teams should plan for additional refinement or alternative texture generation if high fidelity is required.
