I figured out how to do it finally! I did my accessory idea from before, where the hand was a separate accessory so I didn’t have to weld or anchor, and then I made a script to find the function to change the hands to from the orientation of the attachment, this is what you call determination:
Vector3.new(0,0,270+6*(-x/1.2)-30*(x-(4+.5*((x-6)/3))))
I had to test over and over to get it right, took a few hours, luckily I’m good at math
