SSS

The Subsurface Scattering Render Element stores subsurface information calculated from VRayFastSSS2 materials.

Overview

The Subsurface Scattering Render Element stores subsurface information from VRaySSS2 materials 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.

When you render the scene, the added render elements listed in the column on the right, will also render, which can be viewed from the VFB window's channel drop-down menu.
