# clearcoatNormal

Waviness and imperfections for the top clearcoat.

## Declaration

```swift
var clearcoatNormal: PhysicallyBasedMaterial.ClearcoatNormal { get set }
```

## Discussion

Discussion An entity in RealityKit can display a clearcoat, which is a separate layer of transparent specular highlights used to simulate a clear coating, like on a car or the surface of lacquered objects. This property allows you to specify a clearcoat normal and add waviness and imperfections to the top clearcoat. To use clearcoat rendering, set clearcoat to a value greater than 0.0. This example shows how to set the clearcoatNormal using a UV-mapped image: if let clearcoatNormalTextureResource = try? TextureResource.load(named: "entity_cc_normalMap") {     let ccNormalMap = MaterialParameters.Texture(clearcoatNormalTextureResource)     material.clearcoatNormal = .init(texture: ccNormalMap) }
