Wall portals are slightly simpler to implement. The two separate sectors must have the same floor and ceiling heights and the portal linedefs need to be of the same length and angle. | Wall portals are slightly simpler to implement.

The two linedefs will have the 376 and 377 specials (respectively, order not being important) and a common tag (which doesn't have to belong to any sector). | |||
Note that on older Eternity versions, the portal lines needed to be 2-sided and passable, and you had to add a buffer sector behind the portal lines. On the latest versions, 1-sided lines are accepted. The only requirement left is to leave enough space in the void behind these 1-sided lines to prevent actors from bumping on other walls from the same layer. | |||
Here is a diagram on how to set up: | |||
