So I'm trying to add The Gaiter Guard(a TF2 cosmetic for Medic) to my Medic PM, it's boots, a pistol holster, a belt buckle and a strap. I have it attached to the waist of my character which is fine for the holster, and belt(I hid the boots via a technique I found but that's besides the point) but since the strap isn't attached to the shoulder, it clips through my character's body when I crouch or when I pull out a weapon. I tried attaching the bone of the strap to my character's bones but it makes the model move to that bone and it gets scratched or stretched and I can't fix it no matter how hard I try and no matter what I change on the side hud. Can anyone help me?
