I'm trying to make it so that people can create their own maps, customization is what is slowing me down lol.
Perhaps you could create linking blocks: blocks that would be placed wherever you wanted a "portal" (for lack of a better term) and you would right click on one face of a block, then on the face you want it to match up to on the other block, then they would disappear and link together. It would require a lot of travelling back and forth for long-distance portals, since you wouldn't really be able to select a group of faces very easily, but it's the best idea I can think of...
EDIT: Or maybe, you could just have it be an item you right-click with. You would right click the interior face then match it up with another one. For an illustration,
Face 1-->|<--Face 2 (there's no wall, it just directly links up, even if there are bocks behind it)
