7.1 Truelight Materials» Blending: Defines the mixture ratio of two colors. Drag the slider to the leftto increase the intensity of color 1. Drag the slider to the right to increase theintensity of color 2.» Roughness: Defines the amount of diffuse reflection and its complement specularreflection. The higher the roughness value, the more diffuse reflectionswill be rendered.» Flake Size: Sets the flake’s size.» Flake Intensity: Sets the flake’s contrast value of each flake’s normal direction.» Clearcoat Settings Sets the clearcoat color. The clearcoat is a transparent, stronglyreflective paint layer on the base paint 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.» Use orange peel: Activates a noisy bump structure in the shader.• Orange peel frequency: Sets the bump structure’s noise frequency.• Orange peel intensity: Sets the bump structure’s intensity.For further information on the Displacement, Raytracing, Incandescence, Commonand Transparency settings please refer to the ”General Truelight Material Settings”section at the beginning of the chapter.247
