| ---------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- |
| [GeneratePerTriangleUV](/engine/6000.5/script-reference/unityeditor/unwrapping/generatepertriangleuv.md)   | Will generate per-triangle uv (3 UVs for each triangle) with default settings.                                              |
| [GenerateSecondaryUVSet](/engine/6000.5/script-reference/unityeditor/unwrapping/generatesecondaryuvset.md) | Compute a unique UV layout for a Mesh, and store it in [Mesh.uv2](/engine/6000.5/script-reference/unityengine/mesh/uv2.md). |
