Coat Reflection

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

The Coat Reflection Render Element stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in their materials will contain no information in the render pass and will therefore render as black.

The Coat Reflection Render Element is formed by multiplying the Raw Coat Reflection Render Element by the Coat Filter Render Element. So while the raw coat reflection pass gives the full reflection of objects reflecting in the scene, the coat reflection filter sets how much of that reflection should come through in the composite. The two are multiplied together to create the Coat Reflection pass which gives a true representation of the reflection in the scene.
