Tardis effect

[protgent]

is there a way to make a tardis effect? where its small on the outsides but bigger on the inside?

The most rudimentary approach would be a silent teleporter (Boom format and up), where as the player walks through the doorway into the 'bigger' room, you teleport them to an actually bigger room.

 

The more visually cohesive approach would be to use line portals (GZDoom and Eternity Engine format). That would give you exactly what you want, but would be limited to those source ports.

As Bauul suggested, I think you should definitely try using a silent teleporter. There's quite a few interesting ways you can apply these types of teleporters in a map. My favorite uses include: leaving and entering a house or other type of building as well as simulating multiple floors by including silent teleporters on such things as staircases.
