Believe it or not, everything was built without using “ib”. As you can imagine, a lot of scaffolding had to be removed quasi-manually by placing ladders all over the place (just to see haw far you can get by not using console commands). It still lacks a proper interior, though. Still, the building system has come a long way. Hope the performance improvements come along well.
Edit: I wonder if the Ambient Occlusion range is easily moddable. Does anyone know by chance?
