Well, I tried it, and it did seem to work in the viewport, but when I go to export it, it's back to flashing.

I know this question has been asked and answered a hundred times, but I've reached the point where I just have to ask this community. I'm working on a short movie as a tribute to Rick May, and everything has been going smoothly until I try to export it. When the movie is being rendered and it reaches shot 5, which is inside the main building of the map, all the lights are flashing different colors like a strobe light. Anybody know how to fix this?
