I intend trying out Corona sss for human skin but I am a little bit confused on how the absorption and subsurface scattering slot work. For photorealistic skin, u have displacement map showing skin scales and tiny details. I understand its best to use displacement maps than normal maps because of light bounces. U have the reflection map which should be slightly bluish and glossy map. I am wondering if the glossy map should be have a bluish tint as well. Then the diffuse map.
As for absorption map,what kind of map is proper for it? Is it black and white with the dark areas having more absorption and the white areas reflecting more of the light rays? does this mean the dark areas show more of the color in the subsurface scattering than the whiter areas. So that means dark color around the eyes, ears, knees, cheeks,lips or just plug in the diffuse map in the absorption slot? Also the ss slot, would a plain color do,or u need a color map with darker red around the above mentioned areas?
