Automatic outside to underground (and reverse) trigger.
Asset to be placed on the track where train goes underground. Asset will turn off weather for train in focus and restrict camera views.
Use it for tunnels and also any place where the train goes where you don't want rain/snow etc. e.g into a covered station, but please note that the camera will default to the cabview.
Rotate for correct orientation to underground/outside world. Arrow points to the dark side.
