Thanks a lot. I'll look into them. This here looks very advanced, but itll give the main idea of what im trying to do: http://www.satoworks.com/MasterClass/NormalMap.jpg (with the normal map)

how can I do things like these?

its a master class tutorial for facial bones but has shaders as well...

Just want to have the character details like in current generation games , is that hard to do, cause Im gonna skin from scratch and I want to do it right this time.
Much appreciated already, thanks.
