# init(useTintColor:useTexture:outputChannel:outputOpacity:)

Creates a descriptor for the specified combination of inputs and outputs.

```
init(useTintColor: Bool, useTexture: Bool, outputChannel: LowLevelMaterialResource.SimpleSurfaceDescriptor.OutputChannel, outputOpacity: Bool)
```

## Parameters

`useTintColor`

If `true`, the shader reads a tint color from the argument table and multiplies it with the surface output.

`useTexture`

If `true`, the shader samples a texture from the argument table and multiplies it with the surface output.

`outputChannel`

The surface output channel the shader writes to.

`outputOpacity`

If `true`, the shader also writes the computed alpha to the surface opacity output.
