You were able to set the videos on the elevators by setting the variables in this instance before the DLC2 - update (Puzzlemaker) broke it. This instance covers the transition for both the Arrival AND Departure elevators, but does not cover the vmf's for the departure elevator(read below) Name this one 'Arrival_Departure_Trans' with the VMF file name ' instances/transitions/arrival_departure_transition_ents.vmf'. Create one more func_instance entity anywhere a convenient place is right behind the elevator model (but not inside the arrival elevator!). Transition manager is the little boxes behind the elevatorĤ.
