hello , i would like to make this kind of material in zbrush , i figured out its very good for sculpting and presentation. here u can see some of examples... did they downloaded it or make it i dont know
https://pixologic.com/zbrush/downloadcenter/library/ I think thats one called polyskin. It is a nice one to work with, but if you are making game characters I do recommend to set up that pipeline to your final render engine and review your sculpt in their as you go. Zbrush just always looks different.
