As you can see, the smaller brushes forming the arch of the doorway are discolored compared to the surrounding walls. At first I thought it was because I had made some of the arches func_walls- but changing them to world brushes didn't make a difference. And the textures are aligned across the brushes. And it isn't on *all* the arches, just some of them.
Any ideas? I'm hoping there's some RAD setting I don't know that will fix this. Or perhaps it's a light_environment issue? I think most of the problem arches are in rooms with windows.
