i saw a video on youtube of an endless hallway and things that are bigger on the inside made in hammer editor. now it was for the game portal but the concept seems the same and i wish to accomplish it in tf2. in the description of the video he says the effect was accomplished using zone portals. however i checked in hammer (tf2 and portal 2) but i cannot find a zone portal. i can find an area portal but i am pretty sure thats just used for optimization. the jist of it is that i am trying to create a seamless teleport. aka the effect you often see in portal. or something of an endless hallway. comment/suggestions are much appreciated. here is the link to the video i am talking about: https://www.youtube.com/watch?v=_xFbRecjKQA&ab_channel=TonyFox i am not sure if it is possible in tf2. but i would like to know how to seamlessly teleport players.
