How to Set up Vehicles in Unreal Engine | Unreal Engine 5.4 Documentation |...

Hello everyone! I am trying to create a simple vehicle setup for an armored personnel carrier that I have modeled before by following the Vehicle setup steps in the link below. However, after completing all the steps, the vehicle sinks into the ground and does not move. When I simulate the physics asset alone, no problems are seen in the collisions, but when I connect the Chaos Vehicle Wheel classes to the pawn class and run them, such a situation occurs. However, the wheels etc. turn, but the vehicle either lies on its side or collapses where it is. I am looking for a guide that I can learn this job in detail for the military vehicle that I have modeled a lot. I would be happy if you could guide me.

To give information about the vehicle;
the distance between the front and rear wheels from the centers is 3.5 meters. The wheel radius is 60 cm and the width is 40 cm. The wheelbase is 2.4 meters.


Tire dimensions are set correctly for wheel blueprints.
The vehicle is positioned on the X axis with the front facing the positive direction.
I don’t know of any other details to pay attention to other than these.
