blender-uv-ops

Typed UV authoring tools for Blender meshes. Load this skill when a workflow needs UV maps, texture-coordinate projection, unwraps, UV island diagnostics, packing, or normalization.

Prefer blender-mesh for topology and modifier work, blender-materials for material slots, and blender-shader-nodes for shader graph edits. Use blender-scripting only after checking this typed surface.

UV operator paths require Object Mode before changing UVs or selection; Edit Mode data are not read or normalized through mesh RNA. Operators select all mesh faces and UV vertices without changing the scene's UV selection sync setting, including UV maps created without initial selection. Projection, unwrap and packing operators reacquire the mesh and the original named UV layer after mode transitions. A missing layer or failed operator returns an error with a conservative mutation receipt; packing then skips normalization. Callers must inspect success before accepting the UV result.
