The Raw Coat Reflection Render Еlement is analogous to the Raw 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 Raw Coat Reflection RE 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 element, which means these areas render as black. The Raw Coat RE gives the full reflection of objects reflecting in the scene, while the reflection filter Coat Filter sets 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 elements are multiplied, the true level of reflection is given as the Coat Reflection RE. By using these component parts of the reflection, you can fine-tune the reflection in your final composite. |
