Hi! I''m trying to make some kind of cargame. I have five different meshes. Carbody itself and four tires. My problem is that how do I make tires rotate properly with the carbody. Ideas? Anyone?

Why dont you transform all your objects at the same time.

Ie. your main car will be centred upon co-ordinates 0,0,0
then place your tyres at co-ordinates relative to your car body.

First update your matrix with a translation to where you want your car.
Then update your matrix with the rotation.
Then display your car body mesh.
Then update your matrix with the tire rotation (to make them go around).
Then display your tires.

Everything is relative, so it will remain stable.
