Ask the Experts / Scenery Automatically Loading

I am positive this question has been brought up before, but I was trying to show a friend one of my entrances for a newer park I am making and he was not able to view it because of a missing scenery file I had in the park that he didnt have. I was wondering if somebody were to be so kind and refresh my memory on how one is to make it so scenery automatically loads itself when somebody opens a park. (I have seen it done in so many parks). Thank you

just go to the options menu and check the box beside the "Export scenery blah blah...somethin" youll know it when you see it...its at the bottom of the options menu
