While the UVW map modifier is a great and speedy tool to help us get those mapping coordinates sorted there ia another, very powerfull UVW editor called the Unwrap UVW modifier. This tool allows you to manualyy manipulate the mapping of your object, export UV Templates to external image editors and bring those images back again as maps.
In most cases I use this modifier only to generate single face templates but in this video I shwo you my worklfow when I have to create a template for more than one face.
