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.
Attributes
The parameters for this render element appear in the Attribute Editor under Extra V-Ray Attributes.
Enabled – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.
Deep output – Specifies whether to include this render element in deep images.
Filename suffix – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.SSS.vrimg).
