Hi, in the car model is possible to set the values of bump and rebound of the suspensions?
Is possible to simulate a situation like raining, modifying the parameters of adherence of the road surface?
Which types of track models are possible to import?
It's possible to set/alter allot of settings. In every cars directory is a .car file with all the cars settings in it.
I can't answer your rain question very good, I only know that you can alter the stickyness of the surfaces.
Tracks/cars are build with blender. When finished the can be exported to .joe files which are the files used by Vdrift.
.dof files can also be imported from racer.
