macOS LiveLinkHub 5.8.0 preview

Development Platform & Builds
1

I tested the Unreal Engine 5.8 Preview on macOS (Apple Silicon) specifically for the MetaHuman Animator monocular video solve workflow.

After installation, it appears that the MetaHuman integration itself is now present natively on macOS:

  • MetaHuman plugins are included

  • LiveLinkHub plugin structure exists

  • macOS-specific launcher resources exist

  • arm64 intermediates and dylibs are present

  • CaptureManager and related modules are included

However, Live Link Hub itself cannot be launched because the executable/app bundle appears to be missing from the distributed Preview build.

What I found:

  • MacLiveLinkHubLauncherMain.cpp exists

  • macOS Info.plist exists

  • App icons/resources exist

  • LiveLinkHub.Target.cs exists

  • LiveLinkHub.uproject exists

  • Multiple libUnrealEditor-LiveLinkHub*.dylib files are present

  • arm64 build intermediates are present

But:

  • no LiveLinkHub.app

  • no executable in Engine/Binaries/Mac/

I also attempted to generate/build the target manually using:

./GenerateProjectFiles.sh -project="/Users/Shared/Epic Games/UE_5.8/Engine/Source/Programs/LiveLinkHub/LiveLinkHub.uproject" -game

This resulted in:

Precompiled rules assembly '/Users/Shared/Epic Games/UE_5.8/Engine/Source/Programs/LiveLinkHub/Intermediate/Build/BuildRules/LiveLinkHubModuleRules.dll' does not exist.

This suggests that:

  • macOS support for Live Link Hub is actively being integrated,

  • but the binary Preview distribution may currently be missing the fully built/staged launcher target.

My goal is specifically:

  • offline MetaHuman Animator monocular video solves,

  • not Live Link Face / iPhone capture,

  • not realtime streaming.

Has anyone successfully:

  • launched Live Link Hub on macOS in 5.8 Preview,

  • manually built the missing target,

  • or found a workaround for the missing executable/app bundle?
