[Fixed] [UDMF] Monsters being alerted outside of sound boundaries

[HQDefault]

Okay, so I have an issue where monsters are being alerted in this "numbered maze" segment from outside the building, no matter how many sound-blocking lines I add.

 

 

There is an interactive sector portal that allows me to have a rooftop area above this, so I have to imagine that the problem has something to do with how I've implemented the sector portal. Even though none of the portal sectors touch any of this area, and none of the geometry should even intersect at any point. I don't know what could possibly be carrying the sound into there and waking the monsters up. Can someone give me a list of things to look for? 'Cause this is driving me crazy.

I'd start by adding extra sound blocking lines at all possible connection points

I fixed it. I had multiple sets of portals where parallel realities would overlap each other, and I think the sound propagation system just got super confused by this. Changing it into a one-way portal seems to have fixed it.
