### Returns

| Type                                                          | Description                             |
| ------------------------------------------------------------- | --------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | Whether a reflection probe was updated. |

### Remarks

The implementation of this method should update the real-time reflection probes. This is called once per frame during the offscreen camera render.

If you use the built-in [ReflectionProbe](/engine/6000.3/script-reference/unityengine/reflectionprobe.md) component and rely on the built-in culling system (see [ScriptableCullingParameters](/engine/6000.3/script-reference/unityengine/rendering/scriptablecullingparameters.md)), you must call [ReflectionProbe.UpdateCachedState](/engine/6000.3/script-reference/unityengine/reflectionprobe/updatecachedstate.md) to update and provide the appropriate probe information to the culling system.
