I just downloaded the free trial to explore. I have no experience with programming. the screen looks nothing like the tutorials online. How can I begin building a world with this free version?

Hi Ken

Take a look at this thread

You will need to get used to searching the forum too, most answers to questions can be found here.

Unless you are just intending doing level design I would advise you get a good foundation in C++ before attempting to use the engine or team up with an existing C++ programmer.

Have fun
