How extensive can this system be? Does it have to be a constant sound effect, like vader breathing? Or can it have requirements that have to be met in order for the sound to play?
What I mean is, would it be possible to make a character make a light "breathing" sound after they run continuiously for, say, 10 seconds, to show they are getting tired from allt he running? If this is possible, it'd be cool, and would work well for just about any model.
