The Sheen Render Element is analogous to theSpecular Render Element with the main difference being that all Sheen render elements can be subtracted from the main back-to-beauty composite, graded, and added back in.
The Sheen 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 will be colored if the Reflection Color parameter of a material is colored.
