The basic steps to a full body morph are this: (1) Use morph dials on the body parts you want to change to create the morphs on the figure, from head to toe. (2) Choose the Figure > Create Full Body Morph command. Assign it a name like "Sally" or "My Character" or whatever. The name and dial will appear in the "Body" of the character. (3) Go back and zero out all of the morphs you used. (4) Go back to the Body of the character, and dial the full body morph. You should see your character bounce back to the way you had it when all of the dials were set. Start by doing this with just a handful of morphs until you get the hang of it. On the other hand, if you want to create a full body morph yourself, for example in ZBrush, there is a bit more involved. Let me know and perhaps I can work up a quick P5 tutorial.
