It’s solved here.
And EASY, without changing any metahuman blueprints.
After Update to 5.0.1:
→ I activated “Faceware Live Link” Plugin under “Project Settings → plugins”
Restarted UE, packaged the project (dev build). Testrun: works like a charm.
Additional info: I removed my metahuman folder from my little test project before patch 5.0.1. After the Update, i added a freshly downloaded metahuman into the project and placed it on the map.
First package without activated plugin: Same error as before.
Checked installed plugins and enabled the plugin: after packaging the project it runs without errors.
Cross-check with build setting “shipping”: Works fine as well!
