I am making an elevator, and getting help from this site: http://developer.valvesoftware.com/wiki ... _(Portal_2
But when i use the elevator instance. It does not pop up. The little ret box only gets smaller. When i save the map, and re-open it the box is still a tiny red box. What do i do?

Split this off from the contest FAQ since it doesn't have anything to do with the contest itself, but instead with how to use instances. -Hober

Are you using the .vmt included with the SDK, or a custom elevator VMT?

EDIT: I believe the map also has to be saved inside the SDK_Content/Maps folder, and needs to be saved before it shows up.

Make sure your .VMF file is in a directory called /maps, and that the elevator instance(s) are in a subdirectory of the same folder called /instances/
