And now, a repost of the screencaps because I figure I'll replace them soon.
View from BLU spawn, including the farmhouse and RED's mysterious plant. I really want the farmhouse to have siding or something, but I went with brick for now. Also I need to get a shingle texture for the roofs.
The barn so far. I struggled to get this light enough inside and now I think I've overdone it a bit. That hayloft and shelves (which I'll finish populating later) are half of what used to be the huge wall.
The other side of the barn, and the shack. The other half of the giant wall is going to be some generic inaccessible buildings, I guess. For now they're a placeholder metal wall. Still not sure what to do for supports on those stairs.
Point A in all its majesty. It's a loading dock! Notice the skyway and the out-of-service freight elevator. If you sticky jump or noclip you can see the freight elevator's interior stop through the skyway windows, and if you look down into the shaft you can see the car itself. The sniper shack there is temporary; I literally just built the upper deck this evening.
The side room, with a view of the nuclear facility. (Thanks, Void!) That ramp leads up to a train track, which also passes behind RED's spawn. The actual cave has very little detail right now; TF2 has a surprising dearth of props that would work here, and also it's been ages since I've seen a fictitious toxic waste factory. Any suggestions for stuff to watch would be appreciated.
