Nice to see somebody is interested. Thanks man. I’ll try to answer.
Basicly, everything is simple. Cartoon characters needs simplicity.
Skin is the simplest SSS that Cycles has. The key is to have good colors to Radius property. I found it from documentation: “A skin-toned SSS shader with color radius (1.0, 0.8, 0.5).” https://www.blender.org/manual/render/cycles/nodes/types/shaders/sss.html
It also has glossy with frenel. See the picture.
Bumps are just noise texture connected to displacement. See the same picture.
The hair is also about the simplest there is. I didn’t want the most realistic, because when I tried it, it didn’t look good on this head. But two things I did differently than before: There is two hair-sculps, because it was easier to modify it into two separate diretions. And more the B-splines steps, the more fluid the hair has in rendering (it also takes more memory I think). Other settings are only: hairNumber: 400, children: 300 interpolated, CyclesHair shape -0.4, ThicknessRoot: 0.2, Tip: 0.01. Nvidia drivers just updated, and I’m having trouble with the materials tab… so I’ll get back to it.
One of the best Blender hair tuts I have watched is this by Rico Cilliers: https://www.youtube.com/watch?v=8L3wq6d26yI
To get smooth characters I just retopo them. It’s fun with the head and face, even when it takes couple of hours.
