Car Jump To Sky When Wheel Colliders Hit To the Ground

Unity Engine

I really do not understand what the fuck is happening. I put wheel colliders and then when I play start, the car begin to drop and when the wheel colliders hit to the ground, the car springs like crazy to the sky…

So to put the engineer’s 3 minute video into instructions;
Set rigidbody mass to about 2000
Lower the damper to about 1500.

Why on earth would you make a video of that?

Try to add colliders to your car:-)

It actually works! Thanks for providing the solution.

Extremely helpful, thank you. I found that the mass doesn’t need to be so high though, it looks like 200 works just fine.

I had limited success with setting mass to 2000 and damping to 1500. Also, what if the mass needs to be different for other physical reasons?

This worked for me. I tried adding a box collider to my vehicle, and even though this collider never contacts anything this made the wheel colliders work properly. Not sure why, but it seems important to have another collider on the main car body.

hey every one this way didn’t work with me i made a mass =2000 and a damping =1500 and i have the same problem !!!

If anyone is still wondering, check the wheel collider mass. For me, the issue was that the mass of the car’s Rigidbody was 1 and the mass of the wheel’s Rigidbodies was 20. Not sure how this could have caused the issue but making the car’s mass higher(1000) fixed it for me.

Try adding a collider to the body of the car. Using the “SimpleCarController” example, this change fixed the bouncing car issue.

I tried everything said here, but nothing helped. Any ideas what could help please?
