I'm rigging a long necked bird and I'm using splineIK for the neck with 3 circular curves controlling the clusters (point constrain). These 3 control curves are parent constrained to a curve on the base of the neck used to rotate the neck ( this curve is not part of the splineIK).
So far so good! The problem appears when I parent the 'BaseNeck' control curve to the MAIN body control curve that is supposed to control the translate and rotate of the entire upper body. When I do the parenting and move the Main body control curve the neck seems to move twice as the translate value...
I think it's because I can't do a parenting inside another parenting, but I'm not sure. But I can't find another solution to fix that.
