The Subsurface Scattering (SSS) Render Element stores subsurface information from V-Ray Fast SSS2 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.

The Subsurface Scattering Render Element is useful for changing the appearance of SSS2 elements after rendering in a compositing or image editing software. Below is an example of its use.
