Sheen

The Sheen Render Channel is analogous to the Specular Render Channel; the main difference is that all Sheen render channels can be subtracted from the main back-to-beauty composite, graded, and added back in.

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