Making Installed Builds causing FMOD errors

Hi everyone,

I’m trying to make an installed build of the 4.26.1 release with FMOD 2.01.08.

Problem, I can’t because there are these 2 errors :

  • LogFMOD: Error: Failed to load bank lookup
  • LogFMOD: Error: Failed to load asset lookup

Does anyone succeed to make an installed build of 4.26.1 with Fmod 2.01.08 ?

EDIT : The command I used

UnrealEngine\Engine\Binaries\DotNET\AutomationTool.exe buildgraph -target=“Make Installed Build Win64” -script=“Engine/Build/InstalledEngineBuild.xml” -Set:WithWin64=true -Set:WithWin32=false -Set:WithMac=false -Set:WithAndroid=false -Set:WithIOS=false -Set:WithTVOS=false -Set:WithLinux=false -Set:WithLinuxAArch64=false -Set:WithLumin=false -Set:WithLuminMac=false -Set:WithPS4=true -Set:WithXboxOne=true -Set:WithHololens=false -clean

And I do have all the corrects consoles SDKs installed.

Best regards,


Hi Alexandre

We use installed builds internally using a similar build command and we haven’t encountered this type of issue at all.

I’m very surprised that you would get log messages on the LogFMOD channel while trying to produce an installed build, when we make our installed builds it’s just using Epic’s source code so for us there’s no chance of any FMOD specific issues there. Are you adding the FMOD integration to the engine before attempting to build the installed build?

Hi Derek,

I’ve made the installed build with the plugin already copied insind Engine/Plugins.

Furthermore because it was making this error during the building of the DDC and its templates (FirstPerson, ThirdPerson…etc), I tried to make an installed build without DDC… And it worked, the build was successfull and I could package some templates.

Ah okay so it’s actually the DDC build which is failing, I think I can understand why you would get those errors in that context. It would be ideal if it were possible to build an installed build with our plugin but I’m not immediately sure how to fix the problem you encountered, so I’ll add an issue to our tracker so we can review this and figure it out for a future release.

In the meantime your workaround of not building the DDC is okay, I believe an alternative workaround would be adding the integration as an engine plugin after creating the installed build.
