Widget Blueprint could not be loaded because it derives from an invalid class
The blueprint control could not be loaded because it is from an invalid class
To generate node widgets a class must be created
This is my problem when packaging a project with a custom plugin
The reason for the problem: When the compiler is opened, the plug-in is loaded by default after the compiler is loaded.
In the .uplugin file put
" LoadingPhase " : " Default "
" LoadingPhase " : " PreDefault "
It means that the loading order of the plug-ins is mentioned before the compiler is loaded, so that this problem can be solved.
