Irrlicht Engine

If i load one mesh model http://i018.radikal.ru/1106/f2/db37d0e7ef60.jpg
my wheels spinning but car and wheels freeze at one place. But if i load another model http://s08.radikal.ru/i181/1106/22/2097ab09f581.jpg my car is riding and all is as it shoul be...and if i change joint position(to make wheels don`t intersect with car) it`s nothing - problem is steel http://i019.radikal.ru/1106/f2/bfd1dc374e1a.jpg

If the wheels are spinning and the car doesn't move there are two things I can think of:

- the friction ("mu" in ODE) is set to zero
- the wheels don't touch the ground because the car's body touches it instead.

Thanks youre were right problem was in second variant if my car looks like supertruck (i changed distanse between wheels and car) it`s working
