Haylo. Wondering as to HOW exactly I would be able to test my map in BeamNG Drive. Thank you. Thread: http://www.beamng.com/threads/869-New-Map-Mountain-Plains/page4?highlight=Mountain
If you have the full alpha you can spawn a vehicle in your map and it should work as is. F11->Library->Level->BeamNG->BeamNG Vehicle. Collision with objects is set up differently so your trees/etc might not collide.
