These are testrenderings from the famous Emily project.
The Goal of these tests in the first place are, to get a good basic skin shader setup within Blender,and to learn pro and cons of the best methods to setup the best result,with the given reference maps.
Tips and Tricks,CC and Discussion are allways welcome,at the end we can learn from eachother.
I have resized all textures to 3k, because my gtx 970 cant hold all textures at full size.
the scene is lit by one HDRI,with Filmic CM.light strength calibrated to .18 grey mat.i have reduced some displacement scale,otherwise she looks like a orange on full scale.for me this looks more nature like.
edit,in this next render, i reset the displacement scale to 1 ,to the original value as it was scanned.to me it looks a bit to much ,but left it at 1 anyway.i changed the way the specular map was mixed,like the suggestion at the website.but the roughness values are missing, so i startet experimenting with it.for this, i simply inverted the specular maps ,to get roughness values.
for comparsion,this is exactly the same render as before,but i changed the roughness to a power of 2 for a more sweaty shinier skin.
