Hey Everyone,

Yesterday we released various MetaHuman fixes with UE 5.6.1, including fixes within this area. Are you able to update to 5.6.1 and try again?

The alternative is to remove the outfit asset, auto rig and then re add the outfit asset. Does this resolve the issue?

Thanks
James

Hey

At what point are you seeing this, still at the auto rigging stage?

Have you updated to 5.6.1?

What are your machine specs?

Cheers

If you can share with us the complete log file (or at minimum the last 100 lines or so) we can take a look (ensuring you remove any personal info or sending it over DM).

Please also confirm the version of UE are using.
