How can I use an md3 model as a vehicle?

[deathsythe47]

I am trying to take some cars from the Bank Job siege map that are map objects, and turn them into vehicles that you can pilot.

 

However, I cannot for the life of me figure out what I'm doing wrong. I converted the md3 into glm, and made .veh and .npc files(based on swoop). But when I spawn it ingame, it is invisible, and if you try to pilot it, the game crashes.

 

Here is a pk3 of what I have made so far. Any help would be very appreciated! It must be some simple fix that is eluding me. I don't care if there aren't any proper animations, I just want to able to drive the car.

 

Thanks!
