@El'endiaStarman OK, the door models look a little weird (they overlap) but I'm not going to put anymore effort into what was supposed to be a 10-minute test map: mediafire.com/download/cb86n2p66brms63/p2_test.bsp
There's three rooms: two with the doors right next to each other and one with an elevated door. Try it out
Stick it in your Program Files/Steam/steamapps/common/Portal 2/portal2/map
Then open up Portal 2, go to Keyboard -> Advanced -> enable developer console
Then hit backtick and type map p2_test
Gonna go eat lunch
Shit, I made a giant mistake.
@El'endiaStarman Err don't download that one quite yet
Okay, the TF2 update was 2.7 GB and will end up taking about half an hour to download all that. Portal 2 is 6.6 GB, so I expect that'll be an hour and a half.
