Is nostril glow the same phenomenon that causes light to shine "through" solid objects at creases? This often seems to occur when two elements create a crease (fists) or when the two objects are facing each other (armpits, buttocks). The result is a correctly shaded surrounding area with a thin lit area defining the crease. I'm trying to create an example, but of course no luck. The only one I've come up with was a shot from floor level in back, and the area glowing without being lit would put me in the unfortunate position of having to try to figure out what "nude" means in R'osspeak this week.

The picture shows a glowing armpit crease. Very faint IBL/AO and no shadows, and the only other light is a faint spot casting the legitimate shadows. (Man, those Poser guys are Soooo arch! 100% Jpg "compression" means "none"!)
