Migrating blueprints that inherits from C++ classes

Development Programming & Scripting

Hi, i want to migrate some of my bps from one project to another, the problem is, they inherit from a C++ class (apparently i can’t migrate C++ classes) so i just made a new class with the same name and functionality from the one in the original project, and then migrated the blueprints, but the blueprints just says there are compile errors in the new project (what i’ve kinda expected, they just aren’t finding their parent class), but i can’t change the parent class to solve the problem since the editor just crashes when trying to open the bp (what seems to be a known “bug”)

is there a way to fix these problems without remaking all the entire blueprints?

This sounds like it could be a possible bug or a feature needed in the engine (migration of cpp classes).

If you cant even open the blueprint, the next best solution would probably be to remake it. Luckily though, BP nodes can be copy and pasted into a text file. You can easily copy the old BP’s code and just paste it into the new one. Its not very ideal, but it might be the fastest way to getting your project back on track at the moment.
