how to?

Up!

Almost positive you load the _n.dds files and change the alpha channel from white to black.
Read that somewhere, can't remember where though :/

The glow is a part on the mesh itself, you could try deleting it?

I haven't looked at the textures, but if it's the same setup as before, there should be a glowmap ("filename"_g.dds). The lighter the image, the more glow shows through. Make it solid black, and that should kill any glow.
