### Remarks

Used by [XRMeshSubsystem.GenerateMeshAsync](/engine/6000.7/script-reference/unityengine/xr/xrmeshsubsystem/generatemeshasync.md) to request that normals get generated, or by [MeshGenerationResult](/engine/6000.7/script-reference/unityengine/xr/meshgenerationresult.md) to indicate normals were written to the [Mesh](/engine/6000.7/script-reference/unityengine/mesh.md).
