This page provides information about the Sheen Glossiness Render Channel in V-Ray for Blender.
Overview
The Sheen Glossiness Render Channel is analogous to the Reflection Glossiness Render Channel; the main difference is that all Sheen render elements can be subtracted from the main back-to-beauty composite, graded, and added back in.
