Add the character to the project as if it were still using Unreal Engine 5.5. The created MetaHuman Assembly assets will be updated for the new version of Unreal Engine, however, it will not receive any of the improvements made to the new versions.
Migrate
Create a new MetaHuman Character asset for the selected character, with the same parameters as those it has in the web application. The MetaHuman Character asset will be editable so you can continue working on the character, or you can run an assembly pipeline to create updated MetaHuman Assembly assets.
Import and Migrate
Perform both an import and migration as described above.
