Centre pivot of a object and rotation

Hi! I have a object that i’ve made 0,0,0 in world space in Maya. When i take it into unreal 4 the pivot is not cetred. I’m making a tie fighter and have made 4 buttons. They are simple geometry. i want to be able to animate the buttons moving in a specific way. Setting up all the movement shouldnt be too hard. However the pivots are incorrect therefore i’m not sure how to do it. Please help. Thanks!
