There is also another approach to creating normal maps, using a detailed, high polygon count model of the object, from which you extract the normals and map them to the low polygon object which is used in the game.
A nice tutorial for blender can be found here : http://blenderartists.org/forum/showthread.php?t=138194 These are very generic instructions for normal map baking, I didn't try the FG shader yet, so I presume this may need some tweaking, specially regarding the normal space to be used. See http://wiki.blender.org/index.php/Doc:Manual/Render/Bake for more details about normal space. This normal map shader work will be a huge step ahead for image quality in FG, congratulations !
