Packaged Builds keep loosing Events

Unreal Engine
1

I have been having some really annoying issues lately and I don’t know how to solve it. For some reason when I package my game certain events get dropped. They work fine in editor but when I play the packaged build they don´t play and if log them they return as not valid.

I’ve tried validating the FMOD content and dubbelchecking the settings in the project settings but I can’t track down the source of the issue.

I tried duplicating one of these events in FMOD and selecting that instead in UE and that worked but I can’t keep doing such a work around since this problem keeps popping up.

I thought that maybe it was having Studio set to live preview that created some issues with the builds so I stopped using that but it seems it didn’t help.

I would really appreciate help on this :smiling_face_with_tear:

Hi,

Can I grab some more info from you? Specifically:

  • The versions of FMOD Studio, Unreal, and the FMOD for Unreal plugin that you’re using
  • Whether or not you’re using any source control for your UE project that interacts with the built banks
  • A screenshot of your banks in the packaged build’s directories, which by default should be ./{game_name}/Content/FMOD/{platform_name}/
  • Set FMOD for Unreal’s logging level to LEVEL_LOG, and share a log from the packaged build where the issue occurs, as well as any relevant FMOD logs from editor

Hi!

Thanks for responding. I am running Unreal Engine 5.5 and FMOD studio 2.03.06. I am using Git as version control.

I set the Log level and i tried looking for the event in the output when packaging and I found this line:
