We did create a couple of snapshots to allow us to switch audio during game pause, but overall everywhere we go, it all sounds the same. Sure, we have several audio sources providing 3D spatial sound, but nothing describing the changes to the physical space around us.

Ideally, we want to be able to create zones of where the audio should sound differently and then make changes to our mix when a player enters those zones. Let's take a look at a high level view of the village scene and identify areas where sound...
