The Subsurface Scattering Render Element stores subsurface information calculated from BRDFSSS2 materials.  


Overview

The Subsurface Scattering Render Element stores subsurface information from the V-Ray SSS material as an image. This render element can then be used to enhance or color-correct just the subsurface scattering component of the image during the compositing process.



Attributes

The parameters for this render element appear in the V-Ray RenderChannelColor render channels node.

Deep Output – Specifies whether to include this render element in deep images.

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

Consider For AA – When enabled, anti-aliasing is 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.

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

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 Subsurface Scattering Render Element is useful for changing the appearance of SSS items after rendering in a compositing or image editing software. In the example, the scattering color is changed to red using the SSS RE. See the render before and after compositing.



Compositing Formula

The SSS Render Element is added to the Beauty render to form the final image.
