Hey dude, lookin great! Unfortunately I think you're losing some of the gnarly anatomy detail youve got going on when you've baked. Particularly around the jaw and forehead. This might be down to your low poly. Lookin forward to where this goes :)
Thanks! You're right about that disappearing anatomy. It's definitely the low-poly (a crappy zremesh :) ) and the sss. I boosted the normal map here and there where I lost details. I particularly wanted the veins and muscle striations to pop a bit more. Used that horrible zremesh low-poly to get comfortable with Headus..
