Hi Ben,
I know this is old, but wanted to resolve, for anyone else wondering and also because I’ve had many questions answered by stumbling in to your blog :).
This is the basic flow:
Quick Start (audiokinetic.com)
Tldr; is that you create content in Wwise, events, banks, switches, RTPC etc.
The easiest way to interact with the wwise content is via the wwise pickers in Unreal, you can drag an event directly from the wwise tree into your content browser or the level and it will create a UAKAsset that is basically just a wrapper of the Event in wwise, referencing the Id of the event in the wwise project/stored in the soundbanks.
Building soundbanks in unreal actually calls wwise via command line (or their Waapi protocol, depending on your integration) to build soundbanks in the same way that you would in the authoring tool, so building in either location should be the same…
It is super important for your project settings in the Wwise project and the Unreal project to have the exact same generatedSoundBanks set though, else you will get some strange error about Platform being None…
