How to fix double transforms on a character that has blendshapes and changes proportion[Maya]?

mostlyhuman

I am working on a rig in Maya where a human turns into a creature and am trying to figure out how to prevent the double transforms that are caused on the skin from moving the joints from the human position to the final creature position combined with applying a full body blendshape for the metamorphosis effect.  I have one way working using two skeletons which is the usual way of doing this but I really want the challenge of figuring out how to do it with just one rig/one skeleton Thank you for any help or suggestions!

Do you have the blendShape node ordered after skin deformation? If the creature shape was made in the creature pose, you should be good already.

Thank you, it is ordered correctly, blendshapes before the skincluster.  The issue is say for instance the human's shoulders get wider during the animation, so we move each shoulder joint further apart into the new position, But, the blendshape is also widening the shoulders so it creates a double transform and deforms the skin further than its intended target. Hope that makes sense.

Could you add a corrective blendshape generated from the intended target vs the one with double transforms?
