Since not everyone necessarily familiar with creating the trigger and animations for the gates, I offer you here the “drive-through hall for large engineering” of’d like farmer with prepared Tortriggern for AnimationMapTrigger
You have the hall with the GE incorporate into your map and the map of course prepare accordingly for the AnimationMapTrigger.
At the hall itself: This is a drive-through hall for installation with the GE (3604 Triangles, AO texture) .The drive-through hall is so large that a combine with header trailer fits into it.
I have provided the hall with the animations for opening the gates.
