Can anyone help me decipher this statement? ...it was in the 3dsmax help files for Mental Ray. Specifically the statement of re-using the photon map independent of geometry and image size?
When I read this, it sounds to me that if I change the geometry, the Photon Map is still valid. Which doesn't make a lot of sense when I try to think about it.
