The Sheen Reflection Render Channel is analogous to theReflection 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 Reflection Render Channel stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in their materials contain no information in the render pass and, therefore, render black.
The Sheen Reflection Render Channel is formed by multiplying the Raw Sheen Reflection Render Channel by the Sheen Filter Render Channel. So, while the raw sheen reflection pass gives the full reflection of objects reflecting in the scene, the sheen reflection filter setshow muchof that reflection should come through in the composite. The two are multiplied together to create theSheen Reflection pass, which gives a true representation of the reflection in the scene.
