TrueLightMaterialsBrushedmetalMaterialTrueLightMaterials:BrushedMetalMaterialCreates a TrueLight BrushedMetalMaterialto simulate any type of metal surfaces.Material Settings» Diffuse Color: Sets the shader’s diffusereflection color. This is the colorthe shader adopts when the light reflectionof the surface is spread to manydirections.» Glossy Color: Sets the shader’s colorfor glossy reflection. Reflection behavioris described by the law of reflectionwhich states that the direction of incominglight (incident ray) and the directionof outgoing light reflected (reflected ray) form the same angle with respectto the surface normal. Since asurface usually is not perfectly smooth, theorientation of the normals varies, thuscreating a glossy reflection.» Roughness U / V: The roughness parameterdefines the amount of diffuse reflectionand its complement specular reflection.the higher the roughness value, the morediffuse reflection will be rendered.153
