SSS is quite an in-depth topic, one which despite my many experiments I have very little information on. Omnifreaker’s has an extremely basic overview as part of his UberSurface / HSS pages on the site, but there are more options than are described, many of which I’m at a loss as to what effect they have, such as Subsurface Group or Scale.
The problem is I don’t think I’ve ever found a decent tutorial on the subject. The link Szark provides offers some nice settings, but unfortunately it also assumes you have SSS maps (which 90% of figures sadly don’t include) for figures. It also only provides a one-off setting, which might not work for all situations, certainly not in your situation for use on cloth.
Every time I’ve tried to search for a topic on subsurface scatter, it largely tries to describe it with pure maths and no practical application. I’ve yet to come across one which applies both aspects to get results.
