Packaging error with MetaHuman plugin

Unreal Engine Questions
1

Hi everyone,

I’m trying to package my project in Unreal Engine 5.5 with the MetaHuman plugin enabled, but I’m hitting this error during Shipping builds:

Missing precompiled manifest for 'MetaHumanCore',
'C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\Marketplace\MetaHuman_5.5\Intermediate\Build\Win64\UnrealGame\Shipping\MetaHumanCore\MetaHumanCore.precompiled'

This module can not be referenced in a monolithic precompiled build, remove this reference or migrate to a fully compiled source build.
This module was most likely not flagged during a release for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in MetaHumanCore.Build.cs to override.
Dependent modules: MetaHumanConfig, MetaHumanFaceContourTracker, MetaHumanIdentity, MetaHumanMeshTracker, MetaHumanPipeline, MetaHumanPlatform, MetaHumanSpeech2Face

The project runs fine inside the editor, but the packaging step fails with ExitCode=6.

What I’ve tried so far:

  • Cleaned Binaries and Intermediate folders (both project and plugin).

  • Regenerated Visual Studio project files.

  • Verified toolset (Visual Studio 2022 with MSVC v143 – 14.38 and 14.44 installed).

  • Packaging works if the MetaHuman plugin is disabled, so the issue is isolated to MetaHumanCore.

Questions:

  • Is this a known issue with the MetaHuman plugin on UE 5.5?

  • Should I manually edit MetaHumanCore.Build.cs and force PrecompileForTargets = PrecompileTargetsType.Any;?

  • Or is ther

    failed.txt (10.7 KB)

    e an official fix/update for the Marketplace version of MetaHuman that supports Shipping builds?

Any guidance, workaround, or confirmation would be really helpful.

Thanks!

Hello @Cory_Matthews,

This doesn’t appear to be a Convai-related issue. I’d recommend opening a thread on the Unreal Engine forums.
