Point Light & Spotlight Help - Not Showing Light

Hi everyone,

We are stuck and have been looking for a solution for a while. All of a sudden a map we have been working on is having weird light issues.

If we drag a point light or spotlight onto the map it will only show light on movable objects. Static objects in the scene like floors, walls, machines do not show any effect or light from the point lights or spotlights. We have rebuilt lighting, deleted everything, deleted fog and pretty much everything else. We can’t get the lights to show up in the editor.

Any thoughts on what it might be?
