Wwise not being able to load mod soundbank

I am trying to integrate sounds by following https://github.com/satisfactorymodding/Documentation/pull/359 guide draft. I've got to the point that I can successfully play AKAudioEvent in the Editor, but not in the game itself. In the log of the game I see the following (modRef: TestMod, ak event: Play_sample, :

and when attempting to play the event:

Make sure the GeneratedSoundBanks folder (C:/Program Files (x86)/Steam/steamapps/common/Satisfactory/FactoryGame/AK/AKFactoryGame/GeneratedSoundBanks/) exists and is properly set in the project settings.

I am not too familiar with UFS, but I've confirmed that TestMod_soundbank.bnk is in the generated .pak under Content/WwiseAudio/TestMod_SoundBank.bnk". Maybe it tries to load it from the base game for some reason? I'd appreciate any help on how I can proceed/debug this further. Full game log: https://pastebin.com/gv9e76au

When you say it's under Content/WwiseAudio, that's not how folders show up in the pak, so what is the full path to the asset in the pak in FModel?

OocOP•2mo ago

That was from UnrealPak.exe -List command, according to FModel it maps to FactoryGame/Mods/TestMod/Content/WwiseAudio folder, which contains TestMod_Soundbank.bnk. I've also taken a look at FactoryGame-Windows.pak and sure enough it has a path that is reported in error (FactoryGame/Content/WwiseAudio), but obviously my mod bank isn't there. So I wonder where in Unreal+Wwise integration the path of the soundbank is actually configured (and how the guide author managed to make it work)...

Mircea•2mo ago

Yeah, that's not the right path

Mircea•2mo ago

That's what makes Wwise pak the soundbank at the correct location inside your mod's pak

OocOP•2mo ago

nope, used master per starter guide. Will give dev a try, many thanks! It is fine to check it out in-place, right? Or is it better to create a fresh starter project?

Mircea•2mo ago

You can checkout, yeah

OocOP•2mo ago

Worked like a charm! Thanks! For reference, I've used this commit: https://github.com/satisfactorymodding/SatisfactoryModLoader/commit/213878615a56d13df42067fc7a406b73b70675dd
