MetaHuman Auto-Rigging Stuck at 75% / Fails with Error (UE 5.7)

Hi everyone,

I’m facing an issue with MetaHuman auto-rigging in Unreal Engine (UE 5.6).

Whenever I try to create the full rig for a MetaHuman, the process either:

  • gets stuck at 75%, or

  • fails with an error during face auto-rigging

    :warning: Error / Logs

    I am getting errors like:

    • “Auto-Rigging of Face failed with code ‘Server Error’”

    • Sometimes it also shows memory-related warnings

    • What I Tried

      • Reinstalled Unreal Engine

      • Tried in a new empty project

      • Logged in again to Epic account
