Reflection Filter

The Reflection Filter Render Channel stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in their material(s) contain no information in the render pass and, therefore, render black.

While the Raw Reflection Render Channel gives the full reflection of objects reflecting in the scene, the Reflection Filter shows how much of that reflection should come through in the composite. In other words, the filter defines the strength of the reflection, while the raw image defines what is being reflected in the image. When these two channels are multiplied, the true level of reflection is given and produces the Reflection Render Channel. Using these component parts of the reflection, you can fine-tune the reflection in your final composite.

The Reflection Filter channel is a sub-component in the main Beauty Pass.
