# UpdateCachedState()

> Updates the culling system with the ReflectionProbe's current state. This ensures that Unity correctly culls the ReflectionProbe during rendering if you implement your own runtime reflection system.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static void UpdateCachedState()
```

### Remarks

By default, Unity culls ReflectionProbes automatically as part of the built-in Scriptable Runtime Reflection System. However, if you implement your own reflection system, you need to call this function in your implementation of [ScriptableRuntimeReflectionSystem.TickRealtimeProbes](/engine/6000.0/script-reference/unityengine/experimental/rendering/scriptableruntimereflectionsystem/tickrealtimeprobes.md). Call this method once per frame and before the rendering starts to ensure Unity correctly culls ReflectionProbes during rendering.
