But a better solution is to visit this part of the forum :
Tutorials & Other Helpful Information
All you need is an text editor like
NotePad++ to edit the .xml file
You also need an image editor like Photoshop but I think that a freesoft like
The Gimp or
Paint.net
make it possible to edit .tga picture (an image format with a mask)
(i'm not sure for The Gimp and Paint.net)
