Hi, I suspect you try using ‘0’ CJ skin? If so bonne_attach won’t work by default with it so you would need a workaround, yet I highly recommend you to change it with pAttach: https://forum.multitheftauto.com/topic/129019-rel-pattach-optimized-bone-attach/#comment-991624
it does the same yet faster and lighter, however offsets may need to be changed
