Wheel Colliders

Unity Engine

Hi, I try to make an car game. Here my wheel colliders settings:Imgur: The magic of the Internet

Here a video about the problem:

Here another video, this is showing car reaction.

Any idea about reason or solution?

That i show wheel colliders work, a single ray cast, if you want to have correct tyre collisions then you will need to code your own wheel collider system probably using a sphere collider and a coiple of raycasts.

Yes, WheelColliders are physically modeled as single ray casts. In most cases it’s not a problem. For example, in this video you can hardly notice that the wheels are single ray casts (and they are!):

The reactions in your second video are most likely a problem of the suspension settings. It’s difficult to make that part work correctly due to the wheel design in PhysX, the underlying physics engine in Unity.
