I am wondering what I am doing incorrectly with the lighting here. Could somebody please look at the attached file? The model from the front looks fine, but from the back (the attached image) the cube straight in front of the camera appears to have light coming from underneath it, therefore it almost looks like it is not planted on the floor.
Any ideas as to why this is happening? I am using fours lights altogether, and GI photons from the main keylight only. Do I need to create some extra geometry to block out the light? Change GI settings? Move the lights around?
Thank you in advance...
