Why does geometry nested under skeleton not move when you move the skeleton?

I have some hard surface objects nested under the bone hierarchy in C4D R17. This way when i move the bones, the geometry moves with it, no deformation. I export a 7.4 FBX and import that into Unreal 4.11. I have import meshes in bone hierarchy checked and it brings in the model fine. However when i try to mover the bones to animate it the Mesh does not move with it. Any ideas why?
