If you have successfully done the replace body part with prop thing and are looking at a new correctly working figure then the thing to do is- Save out the PZ3

• Open the PZ3 in John Stalling's CR2 editor. (available in the freestuff)
• Delete all Camera, lights, & Document info etc. Open a regular CR2 in the second panel and make comparisons. Pitch what you do not need.
• Now save the PZ3 as a CR2 file to somewhere within the character library.

That's it in a nutshell, if you get stuck holla! :)
