Skies are built differently in UnrealED 3. Instead of creating a sky box, we now have to create a sky dome to implement a realistic sky in our maps. Custom skydome textures are difficult to create and are not yet freely available from the internet. This tutorial will show you how to convert skybox textures into a skydome.

Special Thanks to Fenring for allowing me to update and expand his original Battlefield 2 tutorial for UnrealED.
