This page gives an overview of the Reflection Filter Render Element and explains how it is used.
 

Overview


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

While the Raw Reflection Render Element 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 elements are multiplied, the true level of reflection is given and produces Reflection. Using these component parts of the reflection, you can better fine tune the reflection in your final composite.

Reflection element is a key component in the main Beauty Pass.

Consider for Anti-Aliasing – When enabled, anti-aliasing will be used where possible.

Filtering – Applies the image filter to this channel. Image filter settings are in the Image Sampler tab of the Sampler tab of the  V-Ray Renderer node.

Color Mapping – When enabled, the Color Mapping options in the render settings will be applied to the current render channel.

Derive Raw Channels – Generates data in the raw channels by combining the respective color and the filter color channels.

VFB Color Corrections – Applies the post render color adjustments made from the VFB.
