Can I mix blueprints with C++?

I’m making a single-player RPG using C++ and was going to buy this marketplace product: Dialogues & Quests in Blueprints - UE Marketplace

Can I easily implement this into a C++ project?

Thanks in advance

It would be better if you ask the question to the owner of the asset in the marketplace product page. see the tab Questions > ask a question

It’s possible but you’ll need to do some work.

I’ve integrated Blueprint only assets into my C++ project. If your C++ code needs to talk to the Blueprints provided you’ll need to use subsystems or create a parent class in C++ and re-parent the BP.

As NerdFury suggested, best speak to the developer of the package.
