This page gives an overview of the Reflection Render Element and explains how it is used.
Overview
The Reflection Render Element stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in their materials will contain no information in the render pass and will therefore render as black.
The Reflection Render Element is formed by multiplying the Raw Reflection Render Element by the Reflection Filter Render Element. So while the raw reflection pass gives the full reflection of objects reflecting in the scene, the reflection filter sets how much of that reflection should come through in the composite. The two are multiplied together to create the Reflection pass which gives a true representation of the reflection in the scene.
The Reflection Render Element is a key component in the main Beauty Pass.

Attributes
The parameters for this render element appear in the V-Ray RenderChannelColor render channels node.
Denoise – Enables the render element's denoising, provided the Denoiser render element is present.
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.
Common Uses
The Reflection Render Element is useful for changing the appearance of reflective elements after rendering using compositing or image editing software. Below are a couple of examples of its use.
