9.1 Truelight Materials9.1.2 BrushedMetalMaterialThe TrueLight BrushedMetalMaterial simulates any type of metal surfaces.» Brushed Metal Material Settings» Diffuse Color: Sets the shader’s diffuse reflection color. This is the color theshader adopts when the light reflection of the surface is spread to many directions.» Glossy Color: Sets the shader’s color for glossy reflection. Reflection behavioris described by the law of reflection which states that the direction of incominglight (incident ray) and the direction of outgoing light reflected (reflected ray)form the same angle with respect to the surface normal. Since a surface usually isnot perfectly smooth, the orientation of the normals varies, thus creating a glossyreflection.» Roughness UV: The roughness parameter defines the amount of diffuse reflectionand its complement specular reflection. The higher the roughness value, themore diffuse reflection will be rendered.233
