Ok, I'll be a little more specific this time, seeing as I've basically figured out what I need to do. I need to know where the line "AmbientSoundName=AmbientSound" goes. Does it belong in one of the files in the terrain folders? Somewhere in flight? I looked everywhere, but the fact that there is support for an ambient in the sound list lets me know that it HAS to go somewhere and work. I've got a WAV to fill in ambient sound, I just need to put the line in to activate it. Help anyone?
