Hi, I'm currently trying to add working turn signals and tailights to Kunos's BMW M3, and in order to do that the lights required had to be seperated from their left/right. So I used 3DSimEd and created a version where these are seperate. But I want to avoid online mismatches, so I'd rather use and extension the replaces the model rather then replacing it directly, but I can't seem to get it to work.
