i kno that to make a scene realistic, u can't just use the default sun settings, but is there really any way to tell wut to use/how much lighting effects for a particular setting? some kind of formula? i kno that AS is makin a tut for radiosity, but can anyone/is it possible to make a tut on how to achieve realism using those elements? tell me if i've got anything wrong, but i've only really known about these things for a few days(since there started to be bout 6 posts a day about radiosity in this forum).
