Physics on Wheeled Vehicle Problem(Car rolling Around)

So I am trying to create a vehicle by following this tutorial link:here

I have rigged my very simple model with 4 wheel bones and one root bone at the base of the vehicle. Created a custom physics asset with a cube for the root and spheres for the wheels, wheels set to kinematic. But when I spawn the vehicle in game it acts like its using the premade physics asset which in this case is a sphere and the vehicle rolls around tell it hits my wheels. Also I have measured the wheels and set them to the correct height.

I also modeled this with blender and when exporting set x to forward and z to up. The bones are oriented so the y-axis makes the spin. The animations work and the wheels do in fact collide with the ground.

Thanks!

I have determined that it has something to do with the placement of the root bone and the wheel configs but I have yet to solve the issue.

I got one of my vehicles to work by scaling it using centimeters set to .01 and scaling the car by 100 and then pressing ctrl-A and resetting scale and rotation. But now I have made two more cars and by following all of the same steps I did with the first there is now a new problem. The car’s wheels do not collide with the landscape.

How to get wheeled vehicle from Blender to UE4[UPDATE] - YouTube Have fun:)
