Ah, so sorry for the late answer.Most models don't come with a SSS map. You'd have to draw that yourself in many cases.But to be honest: I don't use them. The sss, if calculated right, often takes care of it correctly.The hair is also just a mesh. There is particle hair, and mesh hairs as you might already know.Mesh is the ingame version. Particle would be the cinematic one. xDI always use the principle shader for my things.Couldn't be more basic, really - but if you fiddle with it, nice results are easy to get.If you ever need more help, you can always note me for details! ^.^
