Here's the lineup of the characters in the family that I have rigged so far; the adult male in the foreground, the adult female next and the juvenile at the far end.  Most of the rigging is identical, but some tweaks are needed to the mouth rigging and the shoulders and neck for each individual figure.  Loading this lot takes comparatively little memory, and the baby won't add a lot more.  I rigged the adult female first and then edited her .CR2 file in a text editor to create the .CR2 files for the other two, then worked in Poser to refine the rigging.
