optitrack animation in real time

hello, one question: can i do a real time animation inside unreal engine 4 with blueprint? i can manage only the rigid body inside the OptiTrack, because we didnt pay for the motive:body license. We had only Motive:Tracker. I dont see anything a bones management to position they. What i saw i think it cant do it, but i am new in ue4. I dont know the really power of it. I can move only meshes but no skeleton or bones.
