I don’t really know when this started happening. But When I try to build using mod bridge models the lights give me purple and black checkers. I tried seeing if there was something like this but there isn’t. I have updated SBEP deleted it from my addons and replaced it with a new thing. I have GCombat core and external as well. I have svn versions for all of these. It is only the lights that are doing this nothing else and only for Modbridge models.
