7 MATERIALS REFERENCE» Clearcoat The clearcoat is a transparent, strongly reflective layer on top of thebase paint layer.» Clearcoat color: Sets the clearcoat color.» Fresnel Term Quality: The Fresnel Term describes the intensity of a reflectionbased on the viewing angle. Its intensity at normal incidence is controlled bythe clearcoat reflectivity or fresnel IOR parameter, depending on the chosenFresnel Term Quality mode.• 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 that iscontrolled by setting the reflectivity parameter.• Use Fresnel IOR: Uses a physically accurate evaluation of the Fresnel Termthat is controlled by setting the refraction index of the clearcoat layer.For further information on the Raytracing, Incandescence, Common and Transparencysettings please refer to the ”General Truelight Material Settings” section at the beginningof the chapter.260
