So far, to give you guys an idea how I modeled the dog is that the dog's head and jaw are modeled as one object. What I like to happen is, I would like just the lower jaw to rotate up and down when he is speaking or breathing with his tounge hanging out etc. Though after I have soft binded the bones to my dog, when I rotate the jaw the upper snout and in front of the neck deforms a little. However, like I said before, I can not use flexors becuase they are not supported in shockwave. So I am asking you guys if there are any other work arrounds I could do to fix this without having the mouth and jaw as sepperate objects?
