Antropus,
Great head
Thanks for posting your sss settings. I noticed it looks like your bump node is connected to a color map, I found this confusing.
I thought usually the bump map was a grayscale.
Also, what is the difference between your epidermal scatter map and your submermal scatter map? It is really hard to tell with the small thumbnails.
I wish more people would post their sss settings like yourself. Would be awesome to see a eye shader setup. You are right they are definetely the hardest part to get right.
Thanks!
