## Discussion

Discussion For a PhysicallyBasedMaterial, object, you can use sheen to add soft specular highlights that simulate subtle reflections like the ones that occur with some materials, primarily fabrics. You can specify sheen using a single color, or you can provide a UV-mapped image.

The following example specifies sheen using a single value for the entire material: let sheenColor = PhysicallyBasedMaterial.Color(deviceRed: 0.8, green: 0.8, blue: 0.8, alpha: 1.0) material.sheen = .init(tint:sheenColor) This example shows how to specify sheen using a UV-mapped image texture: if let sheenResource = try? TextureResource.load(named: "entity_sheen") {     let sheenMap = MaterialParameters.Texture(sheenResource)     material.sheen = .init(texture: sheenMap) }
