Hello there, I was wondering if there is a way for me to change models and so in skyrim, I mean a way that it will 100% work. I'm new to all this stuff, but I really love the steel plate armor look, and dislike dragonplate [or w/e the dragon light armor is] so I've wanted to replace the dragonplate armor model/texture/look with the steel plate. Could someone please explain to me how to do it? And do it so a newbie like me could understand. Thanks a lot for any help provided :)
