I am trying to create a Star Trek Holodeck type scene where you can walk from the starships halls into the holodeck that is running a huge outdoor simulation but when you are in there you can’t see where the halls should be. Kind of like this picture below. I also what to do this without streaming the level.
You’d be making a portal to accomplish this.
you could give the walls a texture from only the inner side. this way they should be invisible from the outside. but that wouldn’t apply for the interior. you could make a collision box around the room and if a player enters you make “get all overlapping actors” for all the interior and set them to “only owner see” (or something similar). same for your own pawn. actually you can do it for the whole room as well.
