If you are rendering in Poser, my suggestion is to: 1) turn off the shadowcasting ability of all lights but one 2) turn off the shadowcasting ability on all walls, ceiling and floor if you are doing an interior scene. 3) on the one light you do have shadowcasting ability turned on with, set the map size to 550 I never use more than 3 light, 4 max, all with shadow casting ability turned off but one. my 2 cents, Davo
