Why after apply constraint model jump or move unexpectedly?
such as this :
and How can I implement physics similar to a real car in Babylon.js?
If you increase chassisMass to 15, for example, the situation is better - https://playground.babylonjs.com/#BR2YCM#17
“Why aren’t these constraints stable?
I’ve tried many times to add constraints to the meshes, but because of this issue, my meshes leave the scene.
Even after increasing the mass, it’s still a bit unstable.”
