I tried setting the spacing to 1, and the autostop to .5 (oh btw if I use count
it doesn't generate the photon map either, I've even tried 2 million photons and
it still wouldn't generate the map)
about 38k photons hit the object, and it just keeps shooting them forever
(meaning the amount of photons that actully strike the object never goes up)
it seems if I specifiy an autostop greater then 0 it will continue to shoot
photons at the object for an infinate amount of time, if I specifiy autostop 0
though it doesn't even build the photon maps....
ugh, I don't have any infinate objects in my scene, just 2 polygon mesh's the
object and the floor, and just to be sure the floor wasn't the problem I put
ignore_photons in the object declaration
