Here's a sample of the effects, using Sphere props. The top left is a reference. All the rest use the system given in the tutorial, **without** the emulation of sub-surface scattering. The Aiko Default is the basic skin setting used for the Aiko 3 figure from Daz; no shaders. The colour is used instead of a texturemap on the others.

Totorial default uses the settings from face_off's Real Skin tutorial, and shows the over prominent Fresnel effect.

The lower two spheres use the same shader tree, with adjustments to the Fresnel Spot node.

Note how the Fresnel Spots interact with the Specularity. It may be I need to reduce the specularity effect a little, and combine Softness with a slightly different Spot Colour.

Rendered with default Firefly settings -- no shadows, no raytracing, possibly a bit too much light.
