The current scene I'm testing lights in consists of a
40 x 40 x 40 cube which is made up of only 6 polygons.
When I place a diffuse light in the South West corner of the room the South wall and West wall light correctly, but the North and East appear fully lit with a bright, even light, when they should be much darker.
I thought perhaps I had the winding backwards on the polygons, or had something screwed up with the normals, so I moved the light to the opposite corner (NorthEast) and now the North and East walls light correctly, with the South and West behaving in the same incorrect manner as noted above.
If smaller polygons is the answer, what size is the largest acceptable?
If any other hints come to mind that are related to this I would really appreciate hearing them
