Wwise picker tab empty and stuck + empty Wwise components - Unity 5.3.4f1 / Wwise latest intergration pack

Question

Hello,

I opened my unity project this morning and my Wwise Picker Tab stopped working. Same for all Wwise components, though there's still sound when playing the game.

I can't move it around and the tab is empty.

I tried to reset layout, but that didn't changed anything.

Console shows this error every time I click on the picker tab:

NullReferenceException: Object reference not set to an instance of an object
AkWwisePicker.OnGUI () (at Assets/Wwise/Editor/WwiseWindows/AkWwisePicker.cs:56)
System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Reflection/MonoMethod.cs:222)

 When I open project I get 4 errors in the console:

iterator == end

AkWwiseProjectInfo:GetData() (at Assets/Wwise/Editor/WwiseWindows/AkWwiseProjectInfo.cs:24)

I re install Unity, doesn't work, I tried uninstalling/resintalling integration package but then all scripts are missing and the installation seems incomplete.

 

Hope someone can help me with this

Answer 1

I just encountered a similar error. I resolved it by deleting and then restoring (from my source control) all the wwise files in my unity Assets folder. Didn't track down exactly what was corrupted. I suspect that my actions forced Unity to reimport the files which cleared out whatever was broken. Just forcing reimport on the Assets/Wwise folder and the WwiseSettings.xml files may be able to solve it.

Thanks for your answer.
I resolved this quite the same way, replacing the all the Wwise files in the Unity Assets folder with a backup.
Though reinstalling wwise intergration after uninstalling/deleting did not work in my case...
