export custom C++ class

I try it but the copied class must be registered in your UE project, it’s not only copy class and add it in you project…
I tried to convert my c++ class into blueprint component to be able to migrate it, a .copy file was generated but I don’t know how to use it to import it from another project
FYI: the migration process is not for me, I would like to send “migration” file to a friend who can be able to import it
