Firstly this is heavy WIP not set the proper collision for the bodyshell yet..... picture has been attached and so has its jbeam file the problem is something about no differential but being a newb at jbeam i cannot figure it out tried copying the correct section from the Semi then removed it again after my bus crashing the game.... any ways to get it working?
Here is your mesh and jbeam, it drives now. EDIT: I added the engine from The Ideal Car. I renamed the slot in this jbeam from idealcar_engine to bus_engine. This is because yours would not move the bus or produce sound. Also I increased the horsepower, renamed the Differentials slots. Put in mods.
