Hi everyone,
My editor instantly freezes as soon as I click on “Download Texture Sources” in MetaHuman Creator under UE 5.8.
Symptoms:
- Clicking the button freezes the entire editor instantly (not just the OS “Not Responding” state — the whole editor becomes unresponsive)
- CPU usage stays stable at ~80% the entire time
- Left it running for a full day with no change — no crash, no error, no recovery
- No error is logged, the log simply stops writing after the EOS SDK boot sequence starts
The log before the freeze :
Requesting texture sources… Blocking: false
Downloading source face textures
Downloading source body textures
LogEOSSDK: LogEOS: Updating Platform SDK Config
LogEOSSDK: LogEOS: [Boot] EOSSDK Version 1.19.1.2-53289219 booting at 2026-07-20T13:56:40.772Z
Isolation steps I’ve done:
- Tested on the same machine, same network, same account
- UE 5.7: Download Texture Sources works correctly (tested on 2 different characters)
- UE 5.8: Fails on a project migrated from 5.7, AND on a brand-new project created directly in 5.8, AND with a fresh unmodified MetaHuman character (not just my customized one)
This strongly points to a specific bug introduced in 5.8, likely related to changes in the Texture Sources / DCC export pipeline mentioned in the 5.8 release notes.
System info:
- UE 5.8
- Windows 10, RTX 3070
Has anyone else run into this?
