Cannot build data after switching to Event Based Packaging with UE4

Question

Hello

I recently switched to Unreal v2.4 and tried to set up the Event Based Packaging. Note that I already had lots of sound events set up in the Unreal project so I was not able to do this with a fresh project.

When I tried to generate my sound data with Event Based Packaging active I got the following error:

[2020.07.01-09.11.08:243][822]LogSlate: Window 'Clear Sound Data' being destroyed
[2020.07.01-09.11.20:899][284]LogAkWaapiClient: Subscription failed: {"details":{"topicUri":"ak.wwise.core.soundbank.generated"},"message":"Invalid Options. Document:'#/bankData'. Schema:'#'. Keyword:'additionalProperties'.","uri":"ak.wwise.invalid_options"}

Does anyone know how to solve this?

Thanks

Answer 1

Try clearing sound data. Then do a sync. And then generate sound data again. I had that issue before and that solved it. Now I only have a problem, that I need to generate sound data every time I open Unreal. Which is kind of annoying.

Did you ever figure out a solution for the second part of your response? the having to generate data every time you open unreal?

Also looking to know if there's a solution to the second problem

Very same issue for the second part, the only way is to clear the asset and regenerate it, but it breaks the reference in the project, and what if the bug come back later ...

Any news ?
