My camera is sort of independent, meaning the user can move it manually as well, without triggering the “teleport” function so to speak,
so imagine the user moves and hits the trigger with the camera, but the camera is just moving back and forth (and not in need to teleport the sublevel forward)
That’s why I have a separated trigger in the main level, which only moves forward if the user activates the “drive” function.
I think I get it though,
I have to set an event for the trigger in the main level,
to check if it collides with “actor has tag ‘sublevel’”
then I have to identify which sublevel it is, then move it 
hopefully I can do it! will update
you’re the best!
