Values
| Name | Description |
|---|---|
| MikkTSpace | Standard MikkTSpace tangent calculation |
| FastMikkTSpace | MikkTSpace-like blended per-triangle tangents, with the blending being based on existing mesh, normals, and UV topology |
| PerTriangle | Project per-triangle tangents onto normals |
| CopyExisting | Use existing source mesh tangents |
