I’m only into about 3 months of UE4, and still feel like a noob, so don’t expect it to all just gel in the first couple of weeks.
There are still some basic things I haven’t worked out, like blueprint communications. Still things I see people talking about and I have absolutely no idea what it is. There is just such a vast amount to learn that you can’t do it any time soon. So, my advice would be to do something like this:
Watch as many videos as you can, just to get a feel for what can be done, and all the different elements that make up UE4.
Try to follow along with at least some of them. You WILL have trouble with some, especially those that assume some prior knowledge, that’s when you pose those ‘dumb’ questions, but people are very helpful in the forums. Don’t be afraid to ask more specific questions.
Make something small. Plan a small game or build a scene or play with the terrain editor, but with some purpose. Plan out what you want to achieve, break it down into small tasks, then set about learning each of those small components, much less daunting when you do it this way.
Get something like a trello account and put all your tasks there, or even just a list of things to learn and you will be much better organised.
That is how I am approaching UE4 which seemed quite overwhelming at first, and still is, and you just want to know everything right away to get that game going, but yeah, unless you are very experienced in gaming engines and game programming in general then it is both a hard slow slog as well as fun. Enjoy the journey as much as the finished project.
Another thing you can do is watch the trailers of people’s projects in the forums and read or ask questions about how certain things were done.
