Robot-arm (RightHand) does not want to move in the animation editor

[gtnz007]

I ran into a problem … when I started creating robo-arms, I broke something in them … or did something wrong … well, “RightHand” now does not move in the animation editor

I don't

Use Anchor on this part.
or welding

it’s just an ordinary hand from “Dummy”

(of course I made L. and U. work but the hand …)

You can lock parts in the animator editor. Make sure you haven’t accidentally clicked on the lock button beside the part name.
