[HELP] Puppet Jawline head and shoulder stretches weirdly during walk cycle in character animator.

[sajanr37955673]

Hi, on applying the walkcycle on puppet, the puppet runs fine ... But the head stretches in and out weirdly at the jaw area and the shoulder area too does the same. I have attatched a video showing the issue. How can I solve this issue to make the movement more concrete without any stretch ? If you want to see the puppet's rig, I have attatched the ".puppet" file too. Please help me with this issue. It is giving me major headache.  @oksamurai @alank99101739
