MetaHuman Version Conflict (UE 5.6 to 5.7.1) and DNA Sync Issues

Summary

Hello everyone,

I’m currently facing a critical assembly issue after updating my project from Unreal Engine 5.6 to 5.7.1. I would appreciate any insights or support from the community.

The Issue:
After the engine update, attempting to re-assemble or import a MetaHuman creates a conflict within the MetaHumans/Common directory. Specifically, the new assets seem incompatible with existing MetaHumans in the project, causing the older characters’ rigs and meshes to break.

Additional Complications:

MetaHuman Creator Loop: When I access the MetaHuman Creator website, I am repeatedly prompted to “Download MetaHuman” despite being logged into the correct Epic Games account (matching the engine credentials).

Quixel Bridge Visibility: My newly created or updated MetaHumans are not appearing in the Bridge interface, making it impossible to manage them directly.

Questions:

What is the best workflow to update MetaHuman DNA files for 5.7.1 without breaking legacy assets?

How can I isolate “Common” folder dependencies so that new MetaHumans do not overwrite or corrupt existing ones?

Any guidance on how to sync these versions properly would be greatly appreciated. Thank you!
