How do I connect two sectors like this?

[justyoberg]

I want to make a map so it looks like the following, the two separate sectors in doom builder, my player start looking straight into sector 2, even though they are separate. How do I link these so that I see through the hall in sector 1 and see the other side, sector 2?
Thanks in advance.

I don't think it's possible unless you use a port that knows how to think with portals. Your best bet for doing that is using Eternity.

Some time ago, someone posted this example for GZDoom

Last time I checked (heard) Eternity had the most complete portal implementation. But even then it was still incomplete (as in, something things don't quite work as expected; such as bullets going through or monsters finding their path through them) I don't remember the details. But it is certainly worth checking out to see if it has everything that you need.
