# MeshGenerationStatus

> The status of a XRMeshSubsystem.GenerateMeshAsync.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.XR](/engine/6000.7/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule

```csharp
public enum MeshGenerationStatus
```

## Remarks

[XRMeshSubsystem.GenerateMeshAsync](/engine/6000.7/script-reference/unityengine/xr/xrmeshsubsystem/generatemeshasync.md) will always invoke the provided delegate when the generation completes. This enum contains information about whether the generation was successful, or if an error occurred.
