Subsurface Scattering in Cycles - Blender Cycles Materials and Textures - page 288

4. Add a Voronoi Texture node (press Shift + A and navigate to Texture | Voronoi

Texture) and a Bump node (press Shift + A and navigate to Vector | Bump). Connect
the Fac output of the texture node to the Height input socket of the Bump node, and
the Normal output of this node to the Normal input sockets of the Diffuse BSDF and
Glossy BSDF shaders, and also of the SSS_group node group.

5. Set the Bump node's Strength to 0.150 and enable the Invert item. Set the Voronoi

Texture node's Scale value to 22.500 .

6. Add a Fresnel node (press Shift + A and navigate to Input | Fresnel) and connect it

to the Fac input socket of the Mix Shader node. Set the IOR value to 3.250 .

Now let's simply add the Subsurface Scattering node group:

1. Add an Add Shader node (press Shift + A and navigate to Shader | Add Shader) and

paste it between the Mix Shader node and the Material Output node. Switch the
connection from the first socket to the second socket (this is actually not required in
this case because the shaders are added anyway).

2. Connect the output of the SSS_group node to the first socket of the Add Shader

node as shown in the following screenshot:
