basically like how to change 1 weapon into another and other stuff like that
The two tutorials I posted the links to explain either REZ or LTB editing. REZ editing explains to change weapon skins where as LTB editing explains how to change specifics about the weapons(RoF/Models/Ect.). How is that not what he is looking for?
OH....if your meaning to swap the skins between to two weapons (G36E to G36E Valkyrie) there is a tut for it but I can't find it...I remember you have to extract the rez files from a Texture rez and swap the names out. (G36E.dtx and G36EValkryie.dtx you must swap the names out.)
