# MeshVertexAttributes

> A set of vertex attributes.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.XR](/engine/6000.6/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule

```csharp
[Flags]
public enum MeshVertexAttributes
```

## Remarks

This enum is used by [XRMeshSubsystem.GenerateMeshAsync](/engine/6000.6/script-reference/unityengine/xr/xrmeshsubsystem/generatemeshasync.md) to request particular vertex attributes, or by [MeshGenerationResult](/engine/6000.6/script-reference/unityengine/xr/meshgenerationresult.md) to indicate which vertex attributes were written to the [Mesh](/engine/6000.6/script-reference/unityengine/mesh.md).
