At end of March I emailed you a set of shaders that included the gen maps. What you can do is load a second copy of the gens into your scene and apply that shader. Then use that as a guide to set it up.

That is basically what I used when I tried to isolate the steps you needed to do to hook up the trans map.

You can apply that shader to the gens, and then just change out the color, spec, bump, and trans maps with the ones you are using.
