BD UV Unwrap
UV unwrap mesh with xatlas (GPU) or Blender Smart UV. Sharp edges from color detection become UV seams for clean boundaries. Methods: - xatlas_gpu: Fast GPU-accelerated unwrap (CuMesh) - blender_smart_uv: Quality unwrap with seam support

| Name | Type | Default | Description |
|---|---|---|---|
| mesh | TRIMESH | — | |
| method | COMBO | blender_smart_uv | UV unwrap algorithm. cumesh_gpu uses CuMesh chart clustering + xatlas packing. |
| seams_from_sharp | BOOLEAN | true | Auto-create UV seams from sharp edges (color boundaries) [Blender only] |
| angle_limit | FLOAT | 661–89 | Smart UV angle limit (Blender) / cone half-angle in degrees (CuMesh) |
| island_margin | FLOAT | 0.020–0.5 | UV island margin |
| chart_refine_iterationsopt | INT | 00–1000 | Chart clustering refinement iterations (CuMesh only). Higher = better charts, slower. |
