Complex Visportals

[Nort]

 

I am trying to segment my map into separate info_locations, and I only know how to seal these locations with normal brushes and visportals. When the player is standing in the street, I want the engine to play street EAX, but if they scale up a building, I want a rooftop EAX. It's not too much to ask for in this game.

...but judging by the attached image of the leak I got, you can't make a visportal out of multiple brushes. Is that correct?

...so now I'm having a warning that these two areas overlap.

...but they could also be overlapping in ANOTHER way, but first let's try to fix this current issue.

Is there a way to perhaps seal locations using some clip brush other than visportals? ...because I'm only interested in sealing in locations and EAX here - not separating the visleaves.

According to this link - https://wiki.thedarkmod.com/index.php/Visportals#Multiple_Joined_Visportals - you can make multiple brush visportals.

...and so in that case, this location overlap might be caused by some sort of invalidation of the shorter of the two visportals, because its nodraw volume - which shouldn't matter - is occupying the same space (as seen to the left in the image) at a 90 degree angle with a third visportal.

If that's the case, can I rotate a visportal brush 180 degrees, without it breaking?

You mean flip it over so that the visportal texture is facing down rather than up? Yeah, that should be no issue.
