## SetShadingRateImage(RenderTargetIdentifier)

```csharp
public void SetShadingRateImage(in RenderTargetIdentifier shadingRateImage)
```

### Parameters

**** (\[RenderTargetIdentifier]\(/engine/6000.7/script-reference/unityengine/rendering/rendertargetidentifier)): The shading rate image to use with variable rate shading.

### Remarks

In a draw call, the final shading rate is influenced by three key components: the base shading rate, shading rate combiners, and the shading rate image. The base shading rate serves as the default when no other specifications are provided. The shading rate combiners dictate the manner in which the base shading rate interacts with the shading rate image. An invalid [RenderTargetIdentifier](/engine/6000.7/script-reference/unityengine/rendering/rendertargetidentifier.md) is the equivalent of [ShadingRateFragmentSize.FragmentSize1x1](/engine/6000.7/script-reference/unityengine/rendering/shadingratefragmentsize/fragmentsize1x1.md) for images.

**Note**: To apply the shading rate value from the Shading Rate Image, set the [ShadingRateCombiner](/engine/6000.7/script-reference/unityengine/rendering/shadingratecombiner.md) for the fragment stage to `Override`, `Min`, or `Max`.
