How can one use akreverbvolumes in UE4 to create ambient zones and room verbs for ak events?

Question

I cannot find any documentation anywhere regarding using akreverbvolumes in UE4. I want to set up ambient zones and roomverbs like I was able to using unreals reverb volumes.

Answer 1

The AkReverbVolumes in UE4 use the game-defined auxiliary send mechanism in Wwise.

1. First, set-up your effects in Wwise. For more information on this, refer to the Wwise help, under  Wwise Help > Using Sounds and Motion to Enhance Gameplay > Managing Effects > Using Effects to Implement Environment Acoustics. Pay specific attention to the sections about Game-defined auxiliary sends.
2. In Unreal Editor, you can add a Ak Reverb Volume to your level the same way you add an Unreal Reverb Volume
3. Once it has been added, go to the volume's Details panel. Under the Ak Reverb Volume section, enter the desired auxiliary send's name in the Aux Bus Name field.
4. Re-generate your soundbanks and preview your level. You should hear the effect on your sound.

If you need an example of this, you can refer to the ReverbDemo.umap level in UnrealWwiseDemoGame, and to the corresponding Wwise project.
