Hmm…this IS confusing. There is a Metahuman SDK on Fab (MetaHuman SDK | Fab), but it is a paid plugin NOT created by Epic but rather by this team: https://metahumansdk.io/ based in Russia.
I wonder what the difference is between the built-in MetaHumans SDK and the MetaHuman Plugin on Fab?
So I proceeded as follows:
- Installed the MetaHuman Plugin from Epic Launcher into UE 5.5.4 binary build installed from Epic Launcher
- Created a new UE 5.5.4 project “MetaHumanTest01” with C++ support from the source code build version of the engine.
- Copied the Metahumans folder from Engine\Plugins\MarketPlace in the UE 5.5.4 binary build to the new project into MetaHumanTest01\Plugins\
- Updated the .SLN file, opened it a built the project with no problems
- However, launching the project gives the same error you mentioned
According to this post, it is possible to avoid the re-compilation process for plugins after moving them, which may or may not help:
Going to give that a whirl here shortly.
