Chapter 7. Subsurface Scattering in Cycles

In this chapter, we will cover the following recipes:

  • Using the Subsurface Scattering shader node
  • Simulating Subsurface Scattering in Cycles using the Translucent shader
  • Simulating Subsurface Scattering in Cycles using the Vertex Color tool
  • Simulating Subsurface Scattering in Cycles using the Ray Length output in the Light Path node
  • Creating a fake Subsurface Scattering node group

Introduction

Subsurface Scattering is the effect of light not getting directly reflected by a surface but penetrating it and bouncing internally before getting absorbed or leaving the surface at a nearby point. In short, light is scattered.

The RGB channels of a surface color can have different scattering values, depending on the material; for example, for human skin the red component is more scattered (as a rough approximation, you could say that the values for the three channels are blue = 1, green = 2, and red = 4).

In Cycles, a true Subsurface Scattering node has...
