The skin looks dry because I'm still working on the roughness but good on you for pointing it out. While it will have a little more oil to it, I'm not going for a super glossy look because he's not meant to be sweating a lot. So I have to play around with the texture in Substance to get the effect I want. Also need to get rid of those eyebrows. Super messy looking. Yes, the brighter areas on the scatter map are meant to allow more of the effect in that area. I may need to darken the grey a bit while leaving the white areas white but again, this is all early stages still. I find the biggest thing that helps skin look realistic though is pores that have direction as opposed to just a simple noise. That's what really sells the look.
