To avoid glitches with geometry when using BPS brushes I converted some of them to shtatic meshes. And I have this weird problem with the way they look: http://i.imgur.com/Fvh1iuV.png
When I get far enough they stop being lighted properly by surrounding lights and just become white.
First screenshots had Preview in the shadows, which indicates that the lighting isn’t built which was why I asked.
Best I can guess is that it’s a lightmap issue, make sure the resolution is high enough and that your UV’s aren’t overlapping or anything. If there’s a problem with the UV’s then it should tell you after you build lighting.
