I think that he has a class in C++ and a blueprint derived from that class. Then there would be a problem with exporting the files and sending them to a friend so he could import them. If I’m right, this is what needs to be done:
- Add the class code to the project and compile it
- Copy the blueprint class file directly from your content directory to another project content directory
- Open DefaultEngine.ini (Should be located at PROJECT_DIRECTORY\Config\DefaultEngine.ini)
- In the section [/Script/Engine.Engine] add:
+ActiveClassRedirects=(ObjectName=,OldClassName="YourModule.YourClassName",NewClassName="YourClassName")
- Start the editor - everything should work correctly
