Converting Vertex-Colored Meshes to Textured Meshes

Summary

Integration tutorial: guide for converting vertex-colored 3D meshes (common output format from generative 3D models like InstantMesh) to UV-mapped, textured .glb files. Introduces InstantTexture, a lightweight library wrapping xatlas UV mapping and barycentric interpolation. The tutorial covers the full technical implementation including texture hole-filling via OpenCV inpainting, median filtering, Gaussian blur, and LANCZOS downsampling. Author notes result quality has “many small artifacts” and is below production standards.

Implications

Open-weights ecosystem health. Generative 3D models producing vertex-colored meshes that most 3D applications can’t directly use is a real format compatibility gap. InstantTexture is a band-aid for that gap — useful for pipelines that need quick UV-textured output without professional retopology tools. The “many small artifacts” caveat signals that mesh quality from generative 3D models is still a meaningful limitation in 2024.
