Physics asset collision don't work

Hello,
I have a car with five collision boxes: One for the body of the car, and four for the wheels
The body hitbox works perfectly but the wheels… well
Everything happens as if there wasn’t any collision box on the wheels
And when I delete the body hitbox, the car isn’t subject to gravity :frowning:

And there is also a wierd scale probleme on the thing on the top of the car (that’s a turret). I don’t know how to fix it, every time I change that it returns to this scale.

Pay close attention to what he does when he exports the car. You have to make sure you update the rotation and scale of the mesh and before you export you make sure to set the x axis as forward and z axis as up.
