A system designed to make it easy to add ambient sounds and music to your level. The open world audio system includes a sound manager that takes care of playing all the sounds, pausing when needed and switching between exploration and combat music. You can quickly set up sounds to blend depending on the time of day. You can add a lot of different areas to your level with each their own sound settings, making it a lot easier to add sounds to your game.

It's been made 100% in Blueprints and it's easy to read/expand upon.

If you're working on a first/third person game this pack could save you a lot of time.
