Thank you Jon, and sorry for the lack of information on the question…
I’m trying to access it from a UVehicleWheel derived class that I made, called UMyVehicleWheel, for instance. I’ve noticed that this class do exactly what you explained here, it gets the VehicleManager class through vehicle, and it work like a charm on base class, but doing so in my derived class, wich is an engine plugin, ends in a unresolved external symbol.
Although, I’m starting to think that it has something related to how I’m calling the vehicle manager in my custom class… Wich is exactly the same as base class.
