I tried this
tool.Equipped:Connect(function(mouse) local RightShoulder = plr.Character.RightUpperArm local LeftShoulder = plr.Character.LeftUpperArm RightShoulder.C0 = RightShoulder.C0 * CFrame.Angles(0,0.6,0) LeftShoulder.C0 = LeftShoulder.C0 * CFrame.Angles(0,-5,0) end)
but it only says that C0 is no valid member of meshpart
