hey i just finished creating this simple mesh by combining three vanilla armor pieces a full body mesh bone structure. everything looks in place, but when i equip the item in game, the mesh is distorted and spiky. i have no idea what to do here and spent the last five hours trying to work around this. so what i'm asking is if someone could take a look at my .nif file and help me troubleshoot.
