Sketchfab is awesome, no question about that.. but right now I'm wondering if there's a way to do screen space SSS and fresnel based effects in a similar way that Marmoset viewer does..? This is incredibly useful for more realistic skin rendering,hair, fur, and other organic stuff, and in my opinion its the one thing holding back all those awesome character works being uploaded. (especially the ones aiming for a bit more realism)
As a character artist I sincerely hope there may be some plans for this in the future, and I'm just curious if you guys think it's at all possible?
Anyway, great site, and keep up the good work!
