Really depends on your goals, I’d say. If you’re (like myself) completely new to this whole scene, I’d recommend looking through some of the documentation and tutorials as a starter. Which sections and specific tutorials I’d point you at would depend, once again, on your goal (IE target platform, game type, etc). In general, it’d be a good idea to familiarize yourself with the general layout of the editor and its basic operation and then start getting a thorough understanding of the blueprinting.
