Some days ago I noticed that some of the weapons on vanilla WoW appear to have a specular map, so I was wondering if it would be possible to edit other weapons and armors textures to add a specular value to their textures, I'm aware that the specular value in the vanilla wow shader is controlled by the alpha channel of the diffuse textures, so maybe adding an alpha channel to the texture of another object would allow it to show specular reflections. I want to test this but I can't seem to find any guide for vanilla wow texture editing.
