Except I'm using the No Suit for G8 Male (and female) rather than the Supersuit, and I use Gimp rather than Photoshop.  I think I can use a Geoshell instead of the basic suit, where I'm stuck though is how to create the emblem in Gimp; the terminology is different so I'm in the dark as far as creating the color (or diffuse) map, the displacement map and the Opacity map. Gimp Gurus, some advice?

 

Thanks!
