If I put vehicle files in the world folder of a map, added it to the .req, placed vehicle spawns in the map and referenced them all to that vehicle for all teams, would it spawn? (Assuming memory pools and everything were set up right) The main question is, will vehicles spawn from a vehicle_spawn if it is only in the world file?
As long as you call the class in the world's .req file and not a sub-lvl file then yes.
