Thanks guys. @Kildor, when I first began this (6 months ago!) you mentioned wanting to play around with it. Now that the design is set, you're welcome to work with it if you want. I've got pretty well formed ideas in my head for the hub and the hangar, but if you wanted to pick
another room from this scheme and work on it, go for it.
@Crystan, in an ideal world we'd match up the UFOs/bases a bit more closely, but I think there are other priorities. The floors are a close match and are the visual link I was going for. (Also, I keep meaning to change that wall texture to remove the xbox visuals, but haven't gotten to it).
