This page provides information on the V-Ray Coat Render Element.


Overview

The Coat Render Element is analogous to the Specular Render Element with the main difference being that all Coat render elements can be subtracted from the main back-to-beauty composite, graded, and added back in.

The Coat Render Element isolates the reflected light in the scene. This render element is an image that stores specular reflection (highlight) information calculated from the material's reflection value in the scene. Specular reflection is defined as the reflection of light from a surface in a single particular reflection, as opposed to a diffuse reflection which is reflected at many angles.

The brighter the area, the more highlight reflection the object exhibits in the render. Specular highlights are colored if the Reflection Color parameter of a material is colored.
