Hello,
Try to use a timeline like : https://forums.unrealengine.com/showthread.php?30924-What-is-the-best-way-to-create-openable-crates-chest-shells-etc&p=122815&viewfull=1#post122815
in this example the chest opens / closes when you walk in out.
Based on the same idea, use a “on click” event (if you want, you can use a “on component click” (right click on a component in the and move only one block of the three, or more) to rotate your blocks (use the play from start instead of play and don’t use reverse.)
If your mouvement goes weird, be sure that you rotate in the right axe and check the origin of your mesh (it has to be at center to be ok.)
