ok, I used the same technique as the salty the seal spine setup in the learning maya book, in which you cluster the curve and set the weights for each of the cvs, only problem is, is that when my t. rex moves the cluster doesn't move with it, it stays behind, but when I make it the child of one of the joints, his neck juts out in front when the joint moves forward and recedes when the joint moves backwards, is there a way to solve this? thanks in advance
