MCP backend
Use when: Full surface texture coverage, sidewall UVs, back cap UVs, closed mesh UV coverage audits, texture fill validation, side/back turntable QA, replacing projected overlays with real surface materials.
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.
Closed Surface UV Coverage
This skill prevents a common false pass: a model looks textured from the front because it has a projected front image or curve overlays, but the closed surface has untextured back caps or plain sidewalls when viewed in a spin/turntable.
Failure modes to catch
- Back detail is only a floating plane or curve overlay, not a material/UV on the back surface.
- Sidewalls have procedural color only; no side UV island, generated/object coordinate material, or baked strip.
- A back projection covers only a center shape and leaves the actual silhouette/back mesh plain.
- Side/back QA uses front-biased frames and misses edge-on/back-on samples.
- Decorative HUD/aura is mistaken for surface texture coverage.
