Interesting thing to look into. I just took the profile from the demo project and haven’t even though of adjusting it.
mostly because it works ok, until you figure out it doesn’t work right at all
And yes, it does seem that there is some amount of scattering always in play, which makes even less sense if you will.
not every object with subsurf will require scattering based on mesh thickness.
I’ll have to investigate this further.
Thanks for exploring options
Btw, as far as the digital human goes, their base image for scattering is basically gray, which should mean that it is always enabled across the whole mesh no matter what.
if I could reduce the amount of scatter visible at .1 that would probably suffice for my character display needs.
unfortunately it doesn’t seem like there is a way to lessen the glow - short of manipulating the sub surf color.
