# FSR2TextureTable

> The set of texture slots available for the FSR2Context. SA GraphicsDevice.ExecuteFSR2.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.AMD](/engine/6000.6/script-reference/unityengine/amd.md)
* **Assembly:** UnityEngine.AMDModule

```csharp
public struct FSR2TextureTable
```

## Remarks

Use this struct to specify input and output textures for the FSR2 implementation.

**Note:** You must create output color texture `colorOutput` with `enableRandomWrite` parameter set to `true` when initializing the RTHandle of the texture. This is due to FSR2 passes requiring access to the resources in a compute shader

Refer to the [Input resources section in FSR2 Documentation](https://gpuopen.com/manuals/fidelityfx_sdk/fidelityfx_sdk-page_techniques_super-resolution-temporal/#id12) for more details.

This texture is mandatory and you must set it to a non-null value.                                                                                                                                                                                                                                                        |
| [exposureTexture](/engine/6000.6/script-reference/unityengine/amd/fsr2texturetable/exposuretexture.md)   | A 1x1 texture with pre-exposure values. If you do not use pre-exposure, do not set this texture. This texture is optional.                                                                                                                                                                                                                                                                              |
