GZDB / ZDoom - 3D Floor with Blocked Sound between upper and lower sections

Hi all,

Is it possible to create a 3D floor where sound is blocked between floor layers? For example, a building where the player can wake enemies inside of it without waking enemies outside on its roof (3D floor acting as the roof / ceiling).

I cannot figure out how to do this, if it's even possible at all. Any help or clarification would be much appreciated!

Thank you!

No, it's not possible at all. Sound propagation works on a sector basis; so if sound is heard in the sector all monsters in the sector will hear it.

I see. I take it there doesn't exist a type of 3D sector which can contain its own sound? Such as, placing an invisible 3D sector which takes up the entire 3-dimensional area that you want to be isolated, and setting said sector to some special type that makes its sound self-contained.

Either way, it sounds like I'll have to work around it for now. Thank you saving me hours of failed attempts at things! ;)
