How to trigger a sound that is NON-DIRECTIONAL?
#1 · May 19, 2011, 3:23 pm
How can I do that? Like the music in Sp you could hear left-right-stereo without any information of the sound-source?s position.
Thanks!

More specifically, go to Flags within the ambient_generic properties and check "Play Everywhere". You can trigger it using a trigger brush so that when the player walks through it, the song starts to play.
