Wwise crashes UE4 while packaging a c++ project

Question

ue4: 4.24
wwise: 2019.2.1.7250

Two issue currently
1) wwise crashes unreal engine during a package of a c++ project. That said, if it's a BP only project (not an option for us though) then it does package, however, we still see problem #2. If I disable wwise package builds just fine, as expected.



 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2) I assume this is the case for c++ too, but can't get that to work. In a BP only packaged project there isn't any audio. In the ue4 log I am seeing the following.

Etc. Today is my last shot at getting Wwise working before we have to go another route, please someone help out!

Answer 1

Hello,

Sorry you are experiencing issues with the integration. Here are a few pointers for your problems:

1) It looks like the Paper2D plugin is crashing during a Commandlet execution. Could you try disabling the plugin? You can do so in the Plugins window (Edit > Plugins). You will need to restart the Editor.

2) There are known issues with the integration and Blueprint-only projects. Could you try converting your project to C++ by following this guide? https://allarsblog.com/2015/11/05/converting-bp-project-to-cpp/, and then packaging again?

Hey this worked guys, thank you. Maybe it would be good to have a "Packaging Unreal Engine 4" section somewhere, with info about things like this. Thank you.
