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

While the Raw Sheen Reflection Render Element gives the full reflection of objects reflecting in the scene, Sheen Filter RE 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 the Sheen Render Element. Using these component parts of the reflection, you can fine-tune the reflection in your final composite. For a visual representation of the formula, see the example.

How to add a render element to a scene

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.

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.
