Nice man. Yeah, I’ve experimented with some nice ambient sounds for an afghanistan type of world. But there’s something I can’t find out, on how to do…
Let’s say I have a larger ambient sphere/box with a common outside stereo ambient sound, but there’s a cabin where I’ve placed an inside room sound. I still want to hear the outside sound on top of it, but not at the same volume when beeing inside the cabin room. So, when ambient boundaries interfere with each other, how do I tackle multiple ambient sources that are in the same area? Just now, everything plays on top of each other.
Another qestion…
Let’s say I have this inside room ambient sound again. I go inside the room and go outside again. Then when I go inside again, how do I make it so the inside room ambient sound doesnt start all over again, but just continue where it was…? Cause it sounds a little weird, when Ive been outside for 1 second, then go inside again and you clearly can hear the the sound has started over again???
Also what if a big “global” atmosphere ambient sound is set, covering the whole level. Shouldnt there be a way to make it stop when you enter an area with a new ambient sound?? Guess it’s connected with the questions above. 
Thx in advance. Hope to get replies, cause this should really work.
