I've put together an illustrated workflow of my latest Unreal 3 map. It is more images and not a detailed explanation as in my previous workflow.
The book begins with an idea and a sketch, then quickly develops into a full blow map from Maya Blocking in stages to Unreal 3.
The workflow is applicable to many game engines, and you do not have to map for Unreal 3 in order to learn from it. It is the workflow that is important.
