Thanks. I edited the .cr2 file, and under the right foot actor, I modified code like this:

---

actor Rfoot:8
    {
   ....
channels
        {
        groups
            {
          ......
            }
rotateZ zRotate
            {
            name TwistRFooty
            initValue 0
            hidden 0
            forceLimits 1
            min -5
            max 5

...

---

So the right foot should now respect -5 +5 rotation on Z axis. Instead, even with forceLimits on, it still rotates with no constrain.
