I conclude that there is no way to get any light into the point of contact if AO is turned on and properly configured to operate all the way into the deepest part of the crack.
In fact, from my understanding of physics, this is correct behavior. In this geometrical situation, no light can reach the point of contact between the two cylinders. Very small amounts can reach very close, but the point of contact gets no direct or bounced light.
Real lips have SSS, so the light can reach the point of contact from under the surface, entering on the front, not the point of contact.
This is why we need SSS.
I could continue this experiment with IDL instead of IBL+AO, but I suspect it will result in the same. There is no direct way to get light into the crevice.
My wife insists I must go work for her now. Hehehe.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
