Is there some skin shader with Unity 5 Please ?
Skin is not part of the standard assets yet but you can either find one on the asset store (this one for instance Unity Asset Store - The Best Assets for Game Making) or implement one yourself now.
The technique used in our demo called The Chase is described in the article Realistic Real-Time Skin Rendering on Mobile by Renaldas Zioma and Ole Cilioxin the book GPU Pro 5 (http://www.amazon.com/GPU-Pro-Advanced-Rendering-Techniques/dp/1482208636).
We are looking into adding one to the standard assets later in the 5.x series.
Im’ not a shader coder, SSS is becoming standard like PBR.
Good.
