Another stab at the LED Panel but with only Radiosity lighting this time. I
prefer it, although there appear to be some odd lighting effects across the
tables surface, almost as if there are overlapping light sources ( theres
only one light ). Does anyone know what might be causing that?
I'm using the box at the bottom of this scene to light it.
