Make hand stop moving

So I have a script that changes the C0 of the left arm but the left arm still moves when I walk, how do I fix this??

SCRIPT

plr.Character.Torso["Left Shoulder"].C0 = CFrame.new(0.900001526, 0.5, 0, -3.47317246e-06, -0.5, -0.866025388, -0.999991298, 6.87056581e-06, 4.37122907e-08, 5.9282861e-06, 0.866025388, -0.5)

Thats the line where I change the C0 of the Left Shoulder.

why are you doing Left Shoulder Should You Use Left Arm Instead Of Left Shoulder

I’m not very familiar with how character animation works, but using weld constraints to weld the whole arm together and weld the upper left arm to the upper torso makes the arm completely still.

Weld Left Hand to Lower Left Arm
Weld Lower Left Arm to Upper Left Arm
Weld Upper Left Arm to Upper Torso

Because thats not the name of the Motor6d

well ummm can you set it to nil i think that would help

What do you mean set to nil? 30chars

Set it to nothing i think that should work
