I am working on a Quake style FPS template. One of the things I would like to do in relation to the teleporters is make it so you can look at a portal and see what is on the other side.
I can get one camera to work. But things get super messy once I try to do more than one. On average you might see 4-5 teleporters in a Quake style level. A common problem I see is the portals are black or sometimes choose to render on the wrong faces.
So what would be the most elegant way to do this kind of thing?
