The most useful things I’ve come across when learning the engine are:
The entire open world kite demo presentation, watched that a few times.
All of the early blueprint lessons, pretty much.
The FBX export page on the docs is useful for going back and remembering the naming convention for collision.
Unreal Engine 4 Course (Create Multiplayer Games with C++) | Udemy As an artist, this is probably the only approachable C++ tutorial on the entire internet. Usually I find everyone ‘teaching’ C++, even the Epic content, does so presuming you already know how to program, finding something that went from square 1 really helped me out.
More than anything else though, the Content Examples sample project. I go to there before anything else every time I have a question on how something works, since being able to interactively modify and tweak what’s there is easier for me to understand than a post on answerhub or the documentation.
