So I've been trying to convert an armor set from oblivion into Skyrim and so far I've gotten the armor into the game and it was fitting and animating properly and it was okay, but I noticed that when I was jumping the main body of the armor was connected to the arms and the back of the helmet was moving in a very unnatural way. I've been looking online but I can't seem to find much information about the issue. From what I've found it looks like a skinning/ weight paint issue, I've tried messing around with the weight paint tool in 3ds max and I've tried outfit studio but all I seem to be able to get is the armor t-posing when I bring it back into Skyrim. Any help would be appreciated especially if you've done this kind of thing before https://imgur.com/a/Ss96u
