9.1 Truelight Materialsthe same angle with respect to the surface normal, thus the angle of incidenceequals the angle of reflection. Since a surface is usually not perfectly smooth, theorientation of the normals varies, thus creating a glossy reflection.» Roughness: The roughness parameter defines the microscopic roughness of asurface. The higher the roughness value, the more diffuse the glossy reflectionswill be rendered.» Clearcoat Settings Sets the clearcoat color. The clearcoat is a transparent,strongly reflective paint layer on the base carbon 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.» Carbon Pattern Settings Defines the carbon pattern.» Pattern Type: There are four different pattern types, according which carbonstructures are usually sewed.• 2 X 2• 3 X 1 staircase• 3 X 1 interleave• 5 X 1» Pattern Size: Sets the carbon structure size.» Pattern Intensity: Sets the fissure depth intensity.» Rotate: Defines the pattern’s rotation value.243
