I'm creating a scene inside of Stonemasons "The Ministry", and I'm having real problems with lighting it. I'm using infinite lights, and they work fine in preview (and the preview renderer), but all the color is leached out (I'm using mostly red lights), and things are much darker in the Firefly renderer. I've an inkling that it might be because the walls (and floor) of the Ministry are blocking the infinite lights (except the white light from above, which can come through the skylights), but In the past if I've had a light behind a prop wall in is blocked in the preview window as well. Odd, that. Any advice?
