The chamfered box with corners has 26 faces...

I have about 17 or 18 angles of which i'm sure about the others is still too much guessing.

It might be a good idea to have something like an edge detection , as it allows some nice rim lights. look at this screen cap : http://www.eclipsemods.com/flyby/screencap.png

I'll be out for 1 or 2 days on the normals research as I need to setup my new 3dsmax4.26. It seems to a be a problematic thing...sigh :(
