Sheen Reflection RE

This page provides information on the Sheen Reflection Render Element.

Overview

The Sheen Reflection Render element is analogous to the Reflection Render Element; the main difference is that all Sheen render elements can be subtracted from the main back-to-beauty composite, graded, and added back in.

The Sheen Reflection Render Element 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 pass and, therefore, render black.

The Sheen Reflection Render Element is formed by multiplying the Raw Sheen Reflection Render Element by the Sheen Filter Render Element. So, while the raw sheen reflection pass gives the full reflection of objects reflecting in the scene, the sheen reflection filter sets how much of that reflection should come through in the composite. The two are multiplied together to create the Sheen Reflection pass, which gives a true representation of the reflection in the scene. For a visual of the compositing formula, see the examples.

How to add a render element to a scene

Properties

Enable 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 of the V-Ray tab in the Render Settings window to this render element. This option is enabled by default.

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

Filtering – Applies an image filter to this channel.

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

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

Example: Compositing Formula

To achieve a more modifiable version of the Sheen Reflection RE, you can Multiply (i.e., set the Blend Mode to Multiply) the Sheen Filter RE by the Raw Sheen Reflection RE.

Example: Enhancing Sheen Reflections

In this example, the Multiplier of the Sheen Reflection RE is increased to enhance the sheen reflections. See the render before and after.
