FINALLY done rendering. Approximately 5 days at 36rpp, then a bit of postwork to try and get rid of some of the graininess and get that look I wanted. Overall, I'm quite satisfied with how this turned out. I'm not going to rerender it (another week is a bit much), but there are some things I would probably fix if I could (and will watch out for in future images): 1) The rear fans and circular walkway still appear to not have fake radiosity applied to them. 2) The texture I chose didn't seem to apply well; perhaps a different method of UVMapping? 3) Definitely make the fans/pipes higher polycounts; they look very awkward as they are now. Any C&C is very welcome and will be extremely helpful to me for future renders of this scale. Thanks! =)
