Here is the start of my lighting for the interior of the submarine. The goal is to keep things quite dark and dim, trying not to over expose things. I have started by using a simple directional, and ambient light which is working well so far. I also have tested out final gather which is just not an option really because after testing it out, the render time increases dramatically. So thats out of the question, however I am starting to get some nice results without it, using just the lights and raytraced shadows. I will keep tweaking and show Andy what I got, some feedback would be good as I could then take that onboard and develop this further in the right direction.
