Is it possible to create a brush that is invisible that you can walk through, and only allow anyone in the brush to hear what you type or say into a microphone? I know you can create invisible, walkthrough brushes, it’s only the latter part I’m curious about.
Basically I want to create sound proof rooms that only allow anyone within the room to hear any noise that occurs in the room. I would link that to a door so that the effect is disabled when the door is open.
Is this more of a Hammer question or a Lua question?
