## Definition

* **Type:** Field

* **Assembly:** UnityEngine.VFXModule

```csharp
public Action<VFXOutputEventArgs> outputEventReceived
```

### Remarks

If you need to store the [VFXEventAttribute](/engine/6000.0/script-reference/unityengine/vfx/vfxeventattribute.md) in the OutputEventArgs, use the copy constructor of [VFXEventAttribute](/engine/6000.0/script-reference/unityengine/vfx/vfxeventattribute.md) or retrieve the value immediately. This is necessary because Unity recycles the [VFXEventAttribute](/engine/6000.0/script-reference/unityengine/vfx/vfxeventattribute.md).
