First, thanks re. the Posette... that is pretty much off the rack, no attempt to spin a character and the texture is c.1998. Lord I got a lot of work done with Posette but I lost most of my stuff to a disc crash from before I had a CD burner. I would kill for a copy of the MorphWorld 2 Disc!!! That is how the basic Posette looks with a single home-made morph... not even the fantastic FBM loaded Eve varient by Traveler, the FBMs of Staale Loseth, or the amazing Nea by pitklad. Poses well... light. Stahlratte made morphs that fix the eyebrows, eye shape, lips and nose without distorting the texture. There was amazing JP injections, geometric eyelashes and stunning characters from Japan. People like RemC made characters you could not believe were Poser 4. Stahlratte made one of the best (maybe THE best) children EVER with Dork. Posette could be a toon, a child, a man. The first cyborg by andygraph was Posette and there were others as good. I still use all the kozoburo P4 hair and some people made great P4 clothes... cyobitlab.hp.infoseek.co.jp is still up.

...while new figures have been more advanced in terms of topology and mapping, they've had fewer innovations and unique add-ons than the original base figures.  Posette still has the most  morphs, and lots of of textures, and a good amount of remaps, and more re-rigging.  she has inspired lots of tinkering because she was that easy to tinker with.  i think it's good that you're planning in good usability.

You put my thoughts much more clearly than I did.
