Does Photon-Light-Mapping take negative photons
(cast from lightsources with rgb <0) in account, or
are they clipped to 0 (like, being exterminated when they
fall below a certain threshold)?
I'm experimenting with using photons for global-illumination
purposes, and my smart-ass brother came up with the idea
of throwing some negative photons around for some "neato"
effects when negative lightmaps are combined with positive
lightsources. But it doesn't work.
Anyone got an answer?
