It is pretty much the same. The original grabbing only grabbed something when you started to press the button, this was changed to continuous checking. The interface is the same but I tend to make most of my blueprints from scratch except for the motion controller and the pawn when it comes to VR. You should be able to copy the pickup cube and just change the interface events to the BI_Pickup. Sorry for the confusion, I probably deleted the PickupCube when I cleaned up the project.
