Let me add some more stuff here: we're discussing digital skin, and physical SSS isn't always the best way to do it. I've tried most the solutions this market offers, and Physical SSS shaders are usually slow, not very flexible and sometimes even prone to artifacts and unusable with GI. I'd rather use a physical SSS shader with materials like jade, milk, porcelain or even plastic. Human skin is a totally different subject: it's not like the human body is made of skin, skin is just the top layer and it's made of 3 sublayers, on the other hand you can safely say that a vase is made of porcelain. Never forget that under your first 2 skin layers (epidermis and dermis) you also have blood vessels (the most important part), and then bones, and so on. Human skin without blood wouldn't look reddish or pinkish, it'd be some kind of unsaturated yellow-greenish material, just have a look at a cadaver for example. That said you'll probably have thought about another problem too: the human body is not a homogeneous structure, the skin of your nose is different from the skin of your hand for example. So how do we solve such a complex problem in CG? The best approach i've tried so far is the Mental Ray one: a fast Skin shader with separate settings for those 3 skin layers. With Mental Ray you can handle those layers separately and you can assign different textures to them: this is quite important since you can treat different areas in a specific way and you can decide how deep each layer will be. You could try doing that in C4D too with the SSS shader, but don't even try, you'd just be wasting your time, trust me, i've already thrown away too many hours trying to use that piece of crap. The C4D SSS is a bad SSS shader to start off with and it's a phsyical one, it's not even something done for human skin specifically. The Brazil, Vray, Modo, G2 and fR solutions are certainly nicer than what i have in C4D, but they're all far behind the Mental Images fast skin shader. Mental Ray also offers a phsyical shader for all those other situations where you need phsyical parameters. I just hope Maxon comes up with something decent in the foreseeable future, they already did it with GI, they can do it with SSS too.
