hello, I was recently working on setting up PXVehicle for my game using PhysX-3.3, but I am having some issues. I tried following the samples but could not get it to work. I tried debugging the wheel query data and it always returns InAir() as true. I might be missing something so please help me. Here’s a video showing the problem: [url][https://vimeo.com/157891304[/url]](https://vimeo.com/157891304%5B/url%5D) Thanks and have a nice day ---

It looks like your vehicle body is hitting the ground rather than the wheels, could you make the ground plane level to see if it works? ---

Hey NickM, thanks for responding but I do not think that is the problem here. I tried increasing the radius of the wheels but the vehicle does not rotate even though only the rear wheels are touching the ground.
