I didn't make it!
I saw a mod the other day that changed hand, and supposedly arm, textures. There was a choice of Duty armor, so i thought i'd pick that. Backed up the files, installed the mod, loaded my game.
But the problem was that only the hand textures were changed; i had Duty hands, but the sleeves were still like they had been before. Now i was wondering if anyone has the time/patience to fix this problem for me, since i don't know anything about skinning/modelling.
The mod can be found here.
