MCP backend
Use when: Texture atlas region detection, per-part UV mapping, front-projected UVs, decal/lightmap handling, texture validation against source templates.
Before the first Blender call, read ../text-to-blender/references/mcp-backends.md. Prefer official MCP for shared capabilities; preserve the selected backend for the whole task. Tool names in recipes are client/legacy examples: map them through that reference and its agent-host guide.
Atlas UV Fitting
This skill exists because assigning a texture material is not the same as fitting a texture.
Supplemental map sanity rule
Do not blindly wire emissive/roughness/bump/lightmap images into every atlas-mapped part. First verify the supplemental map has the same UV layout and semantic region as the basecolor. If it contains aura dots, guide marks, lightmap blobs, or decorations outside the part, leave it disconnected for that mesh and use constant roughness/bump plus explicit edge/glow geometry instead.
