Hi nuno_motion,
Take your polygon model as it is when the Cut is done. (Current State To Object, CSTO)
Shape this Model as you need it after the retractors have been applied.
Next, drag this Model into the Pose Morph, placing it in the lowest position in the list. When prompted, respond to the alert with a confident Yes, indicating that this is an Absolute state.
Set the Model (retractor state) you created with CSTO to invisible for editing and rendering.
When the cut-state is done, animate the (retractor state) slider of the Pose Morph to the level you want.
Examples are below. The first one has both states as absolute, the other one relative for the cut and absolute for the retraction state. Just in case.
