How solve this message?
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! Do you want to continue (it can crash the editor)?
thks! and happy new year.
You probably loaded a c++ project as a blueprint one (via the blue unreal project logo).
Generate your visual studio project file, open it in visual studio and run the project from there. This should make the c++ base classes visible and the project should be able to find it’s parent classes now.
