7.1 Truelight Materialsthe more diffuse reflection will be rendered.On metallic surfaces the roughness can vary against the surface direction. Especiallywhen the surface is finished. Due to this the roughness can be separatelyset in U and V direction.» Metal Type: The Metal Type attributes allows to choose between a wide rangeof metal material presets.» Reflectivity: Sets the Brushed Metal’s reflective intensity.» Clearcoat Settings Sets the clearcoat color. The clearcoat is a transparent, stronglyreflective paint layer on the base metal layer.» Clearcoat Type: The Fresnel Term describes the intensity of a reflection basedon the viewing angle. Its intensity at normal incidence is set by the material’sreflectivity.• Off: Turns off the clearcoat.• Fast: Uses a fast but less accurate approximation to the Fresnel Term.• Accurate: Uses a physically accurate evaluation of the Fresnel Term.» Clearcoat color: Sets the clearcoat color.» Reflectivity: Sets the clearcoat reflective intensity.» Brush Orientation» Brush Mapping: Allows to choose between a range of possible brush orientations,e.g. metal brushed in one direction or metal with radial brushes. For example,Brush Mapping ‘Radial XY’ simulates radial brushes within the xy-plane.The projection planes are defined relative to the object coordinate system ofthe object the material is assigned to.• Size U: Defines the brush’s size on the U-axis.• Size V: Defines the brush’s size on the V-axis.» The properties of the chosen Brush Mapping can be further modified.231
