Ok thanks, just a couple more questions. My map is nearing its finish (Just need to add maybe another room or so, and spawns), but i just tried to export it (f9) to test it out before i go anyfurther and it worked fine without a skybox (Was dark lol) - I then added by one by drawing a massive box around my map, pressed make hollow and set it to -32. When i exported it out like last time, this time i got to "*** Suppressing further FindPortalSide errors.... ***" on the progress box and then it crashed. Is my skybox too big? Or did i set it up wrong or something? When i have smalled maps it seems to work fine.
Also, how do i make the one way thing like on ascent (Where zombies can go in but humans cant get out?)
Thanks.
