Thickness

I've been thinking about fake SSS. I've been thinking it might be useful to be able to have a map of the thickness of the model. This might be part of a backlit SSS look.

 

We can get something that appears to be a thickness map with surface "transparency" and "density" settings...

I've been looking into fake SSS as well and have been thinking that Toonnation's "Villa" is something that might help. "Villa" affects transparency and reflectivity and can make an object more or less transparent at its' edges. I wish it could affect translucency instead of transparency.

 

If we had decal control of translucency, it might also be helpful...but that is currently not available.

 

I saw one tutorial that used translucency along with internal geometry acting as the skull...I can't find it at the moment. It had its' drawbacks, like you wouldn't be able to open the character's mouth, but looked pretty good otherwise.

I like it. Be great to have something like Jenpy's Fast AO... Fast SSS! Don't know if you saw the GPU render demo of Element 3D V2 (due out Dec 2)

 

Go to 20:45 into the movie for some SSS samples. Cool how he uses it on the ferns to lighten them up:

Here's a quick test I did using the Toon render settings...it still needs work and would need to be toned down for skin, but it's a start. There is one light rotating around the dragon model. The model is the Stanford dragon imported as a prop with a material applied. The material has a color, specular color, some specular added and "Toon with falloff".
