I have some beginner questions

I have some beginner questions.
The Main content examples that you are able to download, is there any documentation or tutorials on how they were created? I have watched the basic level tutorial and completed it, but wanted to try some of the other ones if possible. For example:
How would I make a simple solar system and fly the first person camera through it, or a large map like mine craft?

I do apologize for the questions, just so much that this engine offers, some of the simple stuff eludes me. Thanks in advance.

To fly the first person camera, you’d need to use Matinee: UE4 Matinee & Blueprints Tutorial - YouTube

Documentation is available on the Unreal Engine Website (Under learn) and some more documentation is found on the Wiki page.

A Solar System would be a Skybox, with planets and big stars as meshes, but I’m sure you can make particles as Stars.

Creating a simple solar system and fly a first person camera through it would require some scripting/programming, same with making a large map like mine craft unless you’re not planning on making it procedurally generated, but what I’m trying to say is, the level creation tutorial itself won’t be able to teach you everything you need to know. As for you’re question about tutorials on how those content examples were created, I don’t believe there are any, but what I would suggest is that you should look more into blueprints, once you understand how it works, you can look at the blueprints in the content examples and learn from that, blueprints is really nice, once you get the hang of it, you can start doing almost anything you want. Here’s where you can get started: UE4 Blueprint Tutorials

Good luck!
