You probably know ‘highlights’ from the default max
materials. Well, these highlights are nothing more
than fake blurry reflections. A highlight is actually a
reflection of a bright light source.
In previous versions of V-Ray, there was no way to
render these fake highlights with V-Ray materials. At
popular demand, the developers brought fake high-
lights to the V-Ray material.
Note that these highlights will only appear if you use
lights in your scene. The skylight will not generate
highlights.
