The new map utilizes a teleporting system to transition between exteriors and interiors of buildings to cut down on resources. When you walk up to a door, sometimes with and sometimes without clicking 'e', you'll be teleported to a different part of the map.
Every map is limited and lacks some things we all wish the map creator would've put in, but we have the tools to fill most of the gaps. Props, Stools, and creativity. You've all seen plenty of events which required a staff member to teleport you under the map, both to keep the event secluded and allow for creative possibilities that the map's contents otherwise limit.
The following tool would be very useful for more custom locations under the map to be entered outside of events, such as cave systems, bunkers, or even custom buildings using the interior models provided by the map's content itself. By disabling the sound and effects, setting the entity to auto-teleport, and coloring it invisible, the staff will be able to provide map-like teleportation systems.
