I’m sure this has probably been suggested before (it’s a loooooooong thread by now!), but I would like to see a detailed course about highly realistic skin. I’m talking like combining hand-painted color maps with procedural surface bump, along with SSS and a surface reflection layer – the whole nine yards.
These days, there’s a lot of videos that claim to teach how to make realistic skin, which ends up only slightly better looking than wax (i.e., not tremendously that realistic, honestly). I have seen examples of nearly photorealistic skin made from scratch in Blender before, but it seems like achieving such ultra-realistic results is within the reach of a few select wizards of the software. It shouldn’t be!
