This page provides information about the Coat Render Channel in V-Ray for Blender.

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

The Coat Render Channel isolates the reflected light in the scene. This render channel 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 highlighted reflection the object exhibits in the render. Specular highlights are colored if the Reflection Color parameter of a material is colored.
