Given As you can see in the image, I believe I correctly named my objects - namely, 'root'. When I export the armature from Blender 2.8 to UE4, the bone hierarchy in the skeleton looks fine too. It matches the default UE4 mannequin as far as the root, pelvis bones, etc.
Issue As you can see in the .gif, the root bone does not move with the rest of the skeleton. I've been stuck on this for quite some time now. Would really appreciate help
