Unreal4 Level Design

So today I found a great tutorial on setting up a level inside Unreal4. It covers everything from level layout using BSP brushes, to replacing the BSP brushes with static meshes then lighting and texturing the scene etc etc.
You can find the tutorial here: http://www.worldofleveldesign.com/categories/ue4/ue4-how-i-created-the-corridor-environment-in-10-hours.php

I really recommend it. He explains each step in a clear and understanding way and personally I love tutorials which do this. It helps me learn and understand what process I am undertaking.
