## SetTexture(int, int, Texture, int)

Set a texture parameter.

```csharp
public void SetTexture(int kernelIndex, int nameID, Texture texture, int mipLevel)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): For which kernel the texture is being set. See [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md).**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Property name ID, use [Shader.PropertyToID](/engine/6000.6/script-reference/unityengine/shader/propertytoid.md) to get it.**** (\[Texture]\(/engine/6000.6/script-reference/unityengine/texture)): Texture to set.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Optional mipmap level of the read-write texture.

### Remarks

This function can either set a regular texture that is read in the compute shader, or an output texture that is written into by the shader. For an output texture, it has to be a [RenderTexture](/engine/6000.6/script-reference/unityengine/rendertexture.md) with random write flag enabled, see [RenderTexture.enableRandomWrite](/engine/6000.6/script-reference/unityengine/rendertexture/enablerandomwrite.md).

Please note that the mipLevel parameter is ignored unless the shader specifies a read-write (unordered access) texture.

Buffers and textures are set per-kernel. Use [ComputeShader.FindKernel](/engine/6000.6/script-reference/unityengine/computeshader/findkernel.md) to find kernel index by function name.

By specifying a `RenderTextureSubElement`, you can indicate which type of data to set from the RenderTexture. The possible options are: [RenderTextureSubElement.Color](/engine/6000.6/script-reference/unityengine/rendering/rendertexturesubelement/color.md), [RenderTextureSubElement.Depth](/engine/6000.6/script-reference/unityengine/rendering/rendertexturesubelement/depth.md), and [RenderTextureSubElement.Stencil](/engine/6000.6/script-reference/unityengine/rendering/rendertexturesubelement/stencil.md).
