This page gives an overview of the Raw Reflection Filter Render Element and explains how it is used.
The Raw Reflection Filter Render Element is similar to the Reflection Filter Render Element, except it is not affected by the Fresnel falloff. The result is a solid mask showing the pure reflection color as set in the V-Ray Material's settings.
This render element is enabled through the Render Elements tab of the Render Setup window in 3ds Max, and displays its parameters in a rollout at the bottom of the window:
VRayVFB – When enabled, the render element appears as a selection 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 disabled by default.
Multiplier – Sets the overall intensity of the render element, where 1.0 is the standard multiplier.
Denoise – Specifies whether to denoise this render element.
