A Repeat About UnrealED:
But before that, what youll need to know how to use UnrealED. Then youll have to have at least a basic understanding of how to use UnrealEd to make PC Rainbow Six maps. For this, I recommend two excellent tutorials. The first is a general UnrealEd tutorial, designed to teach people the basic tools of mapmaking using the editor. Its written around designing for another game, but most of what it says carries over. The second is a tutorial specifically for using UnrealED to make PC maps for Rainbow Six 3: Raven Shield. 90% of what it says also carries over.
