init(scale:texture:)
Creates a clearcoat object using a single value or a texture.
Declaration
init(scale: Float = 1.0, texture: PhysicallyBasedMaterial.Texture? = nil)Parameters
- scale:
The clearcoat value for the entire material.
- texture:
The clearcoat values as the texture of a UV-mapped image.
Discussion
A clearcoat is a separate layer of transparent specular highlights used to simulate a clear transparent coating, like the paint on a car, or the surface of lacquered objects. Use this initializer to create an object to specify the amount of clearcoat for a material using a single value for the entire material, a UV-mapped image to specify different values for different parts of the entity, or both.
If you specify texture, RealityKit calculates the clearcoat intensity for the entity by UV-mapping texture onto the entity and multiplying the value of each mapped pixel by scale. If you don’t specify texture, then RealityKit uses scale as the entire entity’s clearcoat intensity value. If you provide a color image for texture rather than a grayscale image, RealityKit only uses the intensity of the image’s red channel.
