UDIM Atlas Builder

UDIM to Atlas Conversion for Blender

UDIM Atlas Builder is a production-ready Blender extension that converts multi-tile UDIM assets into optimized single-atlas textures without permanently modifying your original scene.

The addon automatically discovers UDIM material groups, creates working duplicates, bakes multiple texture channels into a single atlas, rebuilds optimized materials, finalizes UVs into the 0–1 space, and exports production-ready FBX files.

Unlike manual atlas workflows, UDIM Atlas Builder automates the complete pipeline while preserving original meshes and supporting mixed scenes containing both UDIM and standard UV assets.

Key Features
