Issue with Wwise SoundBanks Not Converting to .uasset Files in Unreal Engine 5.3

Hi everyone,

I’m experiencing a persistent issue with integrating Wwise with Unreal Engine 5.3. Despite following all the setup instructions, my .bnk files are not being converted to .uasset files, which means they are not recognized in Unreal Engine.

Setup Details:

  • Wwise Version: 2023.1.4.8496.3012
  • Unreal Engine Version: 5.3
  • Integration Method: Followed both automatic and manual integration methods
  • Manual Changes: Added "EngineVersion": "5.3.0" to the Wwise.uplugin file
  • File Paths: GeneratedSoundBanks folder is in the right place
  • Project Settings: Wwise Project Path and Sound Data Folder are correctly set

Steps Taken:

  1. Verified the Wwise.uplugin file is correctly edited.
  2. Regenerated SoundBanks in Wwise and placed them in the correct folder.
  3. Attempted to manually import .bnk files.
  4. Checked Output Log for errors related to Wwise. Logs state the post has failed.
  5. Rebuilt the project and cleared the cache.

Issue: The .bnk files are present in the GeneratedSoundBanks folder but are not converting to .uasset files, hence not being recognized by Unreal Engine.

Notes: I am attempting to play the audio via a post event as per these instructions: Playing Music from a Blueprint

I am using a compatible version of Wwise and I did the integration correctly as well. The plugin is also set up correctly in Unreal and Wwise.

Unreal can currently see anything that has been coverted to a .uasset file. In my case this is my event and some of the default things that come with a Wwise project. These are in the Wwise Audio folder. Unreal is unable to see anything in my actual Wwise project. I have also saved my project correctly and Wwise is connected to unreal correctly. I am able to generate soundbanks via the Wwise browser in Unreal and this succeeds, however, the files still are not converted. I also verified that my Wwise project is in the right place as well. In my case it should be in the content folder.

It is my understanding that I should be able to drag in an event at this point and be able to hear the audio, however, no audio plays. Could this be an issue with Wwise itself or am I missing something?

Has anyone else faced a similar issue or does anyone have any suggestions on how to resolve this? Any help would be greatly appreciated!
