Is it still impossible to import BluePrints that have a parent C++ class to another project?
There is a ‘Export’-function for assets, that can export BPs as text. Changing the parent class to the new class in the *.COPY file is easily possible. But how to import it to the new project?
If you are migrating content from a C++ project to another C++ project, you will not have any custom items such as functions and variables that were compiled in the C++. For that you will need to use Visual Studio and copy/paste the corresponding C++ code from one project to the other and 'Build' again.
Migrating from C++ Project to Blueprint Project
If you are migrating content from a C++ project to another Blueprint project, you will not have any custom items such as functions and variables that were compiled in the C++. You will need to create new Blueprint functions to mimic those created in C++.
Thanks for your answer, but how to migrate the C++ code wasn’t my question. I already migrated all c++ code and the new project compiles just fine. What I wanne do is to migrate all BluePrints that have a C++ parent to the new project, using the new classes.
yes, sure… import says it had worked, but when i try to open the bp in the new project, computer says:
‘Widget Blueprint could not be loaded because it derives from an invalid class.
Check to make sure the parent class for this blueprint hasn’t been removed!’
