Unreal engine and Art work

I've downloaded Unreal Engine, and have tried using it, but at the moment I have very little clue on how to use it. I can make a basic ground area, however texturing and anything other than that, and im gonna need help.

Still using hammer editor from time to time, although it is easier than other editors, I have put enough time into it to know how to make levels. Up until now I've put 200+ hours into Hammer, and hopefully some of the skills will translate over to other editors.

I've again been playing a few games other than CS:GO, (LE hype!). That include outlast, half life, h1z1, and a little WoW. Getting some ideas.
