I also work a lot with fullbody morphs, and ha-ha-, yes they do increase file size a lot.

But PP2012 SR3 has a "partial" solution.

You can selectively delete useless parts from a full body morph.

Example.

A full body morph creates a dial in each and every group of your figure.
Are they all needed? Was each and every group changed/morphed????

Each full body morph creates a dial in the fingers, fingertipstips, thumbs, in the toes, in the eyeballs or cornea's to name a few.
Was something changed/morphed in the FBM there??

If no?
You can safely delete all useless dials from all groups that have "no change" in a particular FBM.

Goto the FBM dial in the parameters palette click the little arrow behind it and click delete.

UNCHECK all groups you want to maintain in that FBM.
Click OK.

All useless dials from that particular FBM are deleted.
