Blueprints vs. C++: How They Fit Together and Why You Should Use Both

It's not an either/or decision. Learn what makes C++ and Blueprints different, what they have in common, and how to use them together effectively. We'll also learn a thing or two about performance optimization and some basic software design concepts.
