Did you add the new events to your Soundbank before generating/updating it ?
To achieve this you have to perform the following steps in the Authoring tool:
- In the Project Explorer, navigate to the " Events " tab.
- Open the Soundbank Manager (by navigating to Views > Soundbank Manager or simply using keyboard shortcut Shift+B)
- Double click on the Soundbank you want to populate. It will open the Soundbank Editor.
- Drag and Drop selected events from the Event tab to the Soundbank Editor.
To help you work more efficiently, Wwise allows you to drag complete structures, work units, and folders, from the Project Explorer into the SoundBank Editor. If these project elements contain child objects, they are automatically added to the SoundBank as well, although they are only displayed on the Edit tab.
If you Generate or Update your Soundbank, you should now be able to successfully post your newly created events in your Unity Project.
