# IProbePostProcessor

> Interface for light probe post processing.

## Definition

* **Type:** Interface
* **Namespace:** [UnityEngine.LightTransport.PostProcessing](/engine/6000.6/script-reference/unityengine/lighttransport/postprocessing.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public interface IProbePostProcessor : IDisposable
```

## Remarks

The interface provides common operations for light probes encoded as [SphericalHarmonicsL2](/engine/6000.6/script-reference/unityengine/rendering/sphericalharmonicsl2.md). Operations include radiance to irradiance conversion, conversion to the format expected by Unity for rendering (refer to [IProbePostProcessor.ConvertToUnityFormat](/engine/6000.6/script-reference/unityengine/lighttransport/postprocessing/iprobepostprocessor/converttounityformat.md)), addition, and scaling.
