I'm having trouble with ceilings duplicating every time lights are added. I posted about it here:

Since that post, it's become a real nuisance in that when I try to do an interior rendering, the ceiling-based lights don't light anything! My suspicion is that the extraneous ceilings are blocking the lights: as if each light cuts through its own ceiling-host and doesn't allow any other lights to cut through. I have to use studio lights.
I didn't experience this issue in Revit 2012. Has anyone else had this problem? Is there a non-studio light work-around?
