Those are separate qualities - use the SimGlass mesh shader for transparency, the specular texture for shine, and the emission map texture for glow. There are tutorials for each but they mostly use Photoshop. It's not hard to translate from working with a texture in Photoshop to doing the same things in GIMP, most of the difficulty is in working with the alpha layer.
I still want to do a tutorial on the emission map, maybe I can expand it to include specular and transparency.
Please do not PM me with mod, tutorial, or general modding questions or problems; post them in the thread for the mod or tutorial or post them in the appropriate forum.
