I fixed the area lights for the bare lightbulbs and I think the lighting is much
better now. I also added more dirt and grime to the floor so it matches the
walls better.
There is still no radiosity. The scene as it is took 3 days, 8 hours to
complete. I had tried starting the render with some very rudimentary radiosity
settings, (the standard #2 from raddef.inc) and after 8 hours it was still
working on the second radiosity pass, so I gave up. I think radiosity really
only helps the floor, and might just undo the darkening I gave it.
Cogito will keep thinking and I'll get back to him at another time. I'm off on
a rabbit hole to clean up all of my code for creating brick walls so I can share
it here.
