How to import correctly a skeletal mesh from 3dsmax for the wheeled vehicle class?

Hi I try to set up a Kart with the wheeled vehicle blueprint class for my MarioKart game. I tried many tutorial to import and set up correctly my kart but there is always a problem.

I tried to rig the kart myself on 3dsmax but it doesn’t work like I want. The bones moved after the import and their axes are not well adjusted.

When I move the Kart the wheels do not turn on themself but around an axe.

I also tried to import whithout rig or skin and separating the wheels from the body of the kart. I followed this tutorial :


But with this the wheels turn properly on theirselfs but the collisions box/sphere dont work well. The kart is always leaning and the wheels cant touch the ground.

Here is my PhysicsAssets file. I tried to change/move/modify every collider but nothing work.

Does someone has any idea to make this work correctly ? Or maybe a recent tutorial working on UE4 4.17 ?

Thanks you

PS : I hope my english isn’t too bad
