When an object such as a car is painted, the paint job is finished with a clear coat, a transparent protective coating applied on top of a colored base coat that creates a shiny and reflective surface. The clear coat has the effect of creating a secondary sharp highlight on the surface. Turn on clear coat highlights to produce this effect and make your materials look extra shiny with two specular highlights.
Adjusts the color of the clear coat highlights. For details on how to use these controls, see: Change colors. White is often a good color for clear coats, but you could darken it slightly for interesting effects.
Adjust Highlight size, Highlight transition, and the reflectivity graph the same way as described in Basic reflectivity parameters.
