Are you exporting tangents or generating them in engine? Try both options https://docs.unrealengine.com/latest/INT/Engine/Content/FBX/ImportOptions/index.html
You want to do this in Engine. See about editing the physics bodies. https://docs.unrealengine.com/latest/INT/Engine/Physics/PhysicsBodies/Reference/index.html
