I’m very new to animate tools. I’ve searched on youtube and also saw this devforum post How to animate Tool Parts (Guns, Knifes etc.) that doesn’t work. Please help me with this

What doesn’t help, are there any errors?

Yeah, I get errors like “Too many motor6ds” and also I cant make the handle stick to the hand while animating
