UE is pretty simple and easy to learn. However, there is a lot to learn so some people might feel overwhelmed.
The best thing you can do is just break it all down into general areas of study, just like how the tutorials are broken up, and then put it into practice. It’s no different than trying to learn any other engine or 3d program. You’ve got to learn the basics.
The biggest problem I see beginners doing, is trying to make everything look good before it actually functions properly.
