Deploying FMOD to XBox One (UE 4.8.0)


When I package my game I get the following error:

MainFrameActions: Packaging (Xbox One): InternalUtils.SafeCopyFile: SafeCopyFile D:\src\MyGame\Plugins\FMODStudio\Binaries\XboxOne\fmod_gain.dll D:\src\MyGame\Saved\StagedBuilds\XboxOne\MyGame\Plugins\FMODStudio\Binaries\XboxOne\fmod_gain.dll
MainFrameActions: Packaging (Xbox One): InternalUtils.SafeCopyFile: WARNING: SafeCopyFile Exception was Exception in mscorlib: Could not find file ‘D:\src\MyGame\Plugins\FMODStudio\Binaries\XboxOne\fmod_gain.dll’.

I was wondering where I find this fmod_gain.dll for X1? It wasn’t in the download that we had.

Or is there something that controls which .dll’s should go into the package and is that dll actually not required?

Ran into the same issue when building for Win32. We’re running the latest patch (fmodstudio10608) on ue4 4.8.3

We found that going back a version of fmod (pre UE4.9 support) fixed this for us.

Yeah we also found reverting to the previous UE4 integration patch (fmodstudio10607) fixed the issue.

A reference to fmod_gain slipping into the last release in FMODStudio.Build.cs. Removing that line will fix the error.

The latest build.cs file has been updated here:
