Hey Cole,
Have you tried setting up two trigger boxes, one to activate and one to deactivate? This would work well if you put the trigger boxes in front of the doors. Even if you were to load levels in-between buildings, you could set the boxes up at the entrance/exit of the door on either side which would work the same way.
I believe this example will get you what you’re trying to achieve. Please let me know if you have any further questions.
Thanks!
