Roughness
trait Roughness: .doc: """ Surface roughness attempts to model microscopic irregularities on the surface causing reflected light to be more diffused. A higher roughness value will result in wider specular highlights. If an roughness_map is provided, the sampled values is scaled by the constant roughness value. Otherwise, the roughness value is used as is. """ roughness is Real: 1.0 roughness_map is Visuals.Textures.DefaultTexture
