NVIDIA GameWorks Integration

Guys, I’m trying to add buoyancy to my ship in waveworks-4.16. But when I add the FloatingSphere component to the ship BP it starts float like a sphere (by the Z axis only). Is there a way to make ship floating in a realistic way? Maybe just to add like 4 FloatingSpheres and somehow set a location for each one (by default there is no way to set location).

Thanks for any help.
