Hi, this is the improved set that I've used in the track named Nova Agri.
I've work in the transitions doing them as smooth as possible with my limited skills with mesh modeler.
This set is completely outclassed by this other set by arnoosel, I would recommend using that instead of this one:
However, I'll leave this here in case you wanted to use it too :D(Updated relative to the desert car update)
Enjoy mapping and have fun ;D
