Warning: As of Eternity Engine v3.33.33, normal anchored portals should no longer be used for two-way setups, where both areas of an anchored portal are visible from each other. Use the new two-way types discussed below instead for this situation. If the lines above are used instead, the player may see seemingly spontaneous error messages and feel annoying pauses during gameplay. | Warning: As of Eternity Engine v3.33.33, normal anchored portals should no longer be used for two-way setups, where both areas of an anchored portal are visible from each other.

The portal transfer linedef allows the effects of any type of portal to be transferred to the front side of a one-sided line. To accomplish this, simply give the 289 line the same tag used by the portal control linedef which is being targetted. Any number of 289 lines may share a portal, and the portal may still be used normally. If the normal effect of the portal (applied to a floor or ceiling) is not needed, it does not have to be tagged to a sector. | The portal transfer linedef allows the effects of any type of portal to be transferred to the front side of a one-sided line (it will *not* work on 2S lines).

In this example, sector C will be visible in sector B's ceiling as a skybox. However, it will also appear on the line in sector A with special 289, giving it a window-like effect. | In this example, sector C will be visible in sector B's ceiling as a skybox.
