Hmm. Where do you find those figures?

All I see is the Project Human figures, and the Poser Pro Tutorial figures.

Not sure what the poly count is on the Project Humans but the tutorial female is over 31K, higher than Roxie, but has very similar mapping and topology, almost makes me wonder if they might be the same mesh. Are they also open source?

Then there's the Poser 4 lo res figures but I doubt that's what you meant.
