It looks like i'm starting to figure this GI out... anyway specs for this image are as follows.. one semiclosed room.. (for light relfections) one point light. render = raytrace global ilumination = photon mapping #photons = 3,000,000 shadows=on render time = 9min 45sec.. anyway better than 4 hours!.. i think i still need to improve quite a bit more... i think it need more contrast.. not sure? opionions?
