Jeronimo,
I've just addressed the weird lighting on a few hangars that you've worked on here. (My thread--first asking about the weird roof lighting--is in The Lounge.) This required to fix a lot of badly defined surface normals, and add extra vertices so as to make the required surfaces. I was planning to release this mod soon.
(In the case of the huge Kiev hangar, My main fix was the bad material mapping for the 2nd LOD--by simply removing that LOD. And I did slightly change the shape of the 2nd lowest LOD, and tweak its texture a tiny bit, all for a smoother transition.)
If those buildings with the curved surfaces have been fixed in these respects, the only one I would have to offer--so far--is the Pacific building Hangar_PBY, which is a low, boxy thing with no curves.
I don't want to have unnecessary versions of the same buildings floating about.
