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.

VRayVFB – When enabled, the render element appears in the V-Ray Frame Buffer.

Deep output – Specifies whether to include this render element in deep images.

Color mapping – Applies the color mapping options specified in the Color mapping rollout (Render Setup window > V-Ray tab) to this render element. This option is enabled by default.

Multiplier – Sets the overall intensity of the render element, where 1.0 is the standard multiplier.

Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
