* **Assembly:** UnityEngine.CoreModule

```csharp
public static void SetCustomShader(BuiltinShaderType type, Shader shader)
```

### Parameters

**** (\[BuiltinShaderType]\(/engine/6000.5/script-reference/unityengine/rendering/builtinshadertype)): Built-in shader type to set custom shader to.**** (\[Shader]\(/engine/6000.5/script-reference/unityengine/shader)): The shader to use.

### Remarks

This is only used when built-in shader is set to [BuiltinShaderMode.UseCustom](/engine/6000.5/script-reference/unityengine/rendering/builtinshadermode/usecustom.md) mode; see [GraphicsSettings.SetShaderMode](/engine/6000.5/script-reference/unityengine/rendering/graphicssettings/setshadermode.md).
