Just experimenting around, I downloaded the best car model I could find that I thought would be easy to modify and work with in the game that I liked.
It just so happened I found a model of a car used in the scenery on the Left4Dead games published by Steam, and so I worked with that.
Heres an inside view, to start you all off :
Seating for 5!
Now for the obvious thing - this model is from the Left4Dead series games. I did get it off a free models site, but that doesn't neccesarily mean I have permission to use this model. So really use this mod at your own discression. The internals do lack polish, but then polishing something I didn't make entirely or even have permission to use, seemed a bit daft.
Still, I figured there were definately good uses for it. By seating 5, two things happen. First, the 4th and 5th portraits glitch and overlap on top of the MET thing up the top left. oops. But also it means you can fill up a crew tank in one go, with a vehicle that can take itself there made of only 2 parts.
Its also a pretty good laugh if you stuff a rocket on the back.
Anyway, you can download it here :
Requires Tosh's cart mod, which is included in the plugins folder of the .zip file.
