This page provides information about the SSS Render Element in V-Ray for Cinema 4D.
Overview
The SSS Render Element stores information calculated from Subsurface Scattering materials (VRayFastSSS2/VRayMtl). This render element can then be used to enhance or color-correct just the subsurface scattering component of the image during the compositing process.
This render element can be used to enhance the SSS layer of objects. See the example.

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: Enhancing SSS
In this example, the SSS layer of the human and the beach balls are enhanced after rendering using the SSS Render Element. The objects are selected using Cryptomatte masks. The human has been darkened by setting the Render Element multiplier to 0.5. The beach balls are brightened using an Exposure layer.
