I am trying to have make a car dealership, I have demo cars, and whenever you go near one you are supposed to get a proximity prompt asking you to buy it.
The proximity prompt only shows up in a small area near spawn, everywhere else it does not show up, even though the max activation distance is set to 10.
That explains it… your vehicle has a very large bounding box, which means there are parts in there that are far away from the actual vehicle. This is going to cause other issues for you with the actual vehicle.
