Unreal is importing everything as separate objects


So here is my problem. I have animated model with constraints but without bones in Maya. Before exporting it to Unreal I baked everything. When I’m exporting, I’m exporting only meshes (not any shapes, constraints, locators). The objects hierarchy is good I think because everything is linked to one dummy object. But when I import my animated model to Unreal, it is separating everything (about 20-30 objects), which is making very difficult to put everything in sequencer and then putting animation files and etc. Please someone help me.
