Poser 3 didn't have conforming.  In the P3 days, a separate clothing figure had to have the same pose applied to it, to achieve the basic effect that conforming clothing automated.  I think it was more common in the P3 days to build figures with built-in clothing, along the lines of the "business" and "casual" figures.  Some figures did use morphing and texturing to achieve the basic look of being clothed.

Or so I gather, based on freebies and forum threads at the tail end of the P3 era/beginning of the P4 era.  :lol:  I missed most of that, myself.  Very few seem to remain, from that era.  PhilC is one of the P3 folks, I think, and he may still have his freebies from that period available.

As I understand it, Poser 3 was the first version to include Zygote figures, which was a huge jump forward from the simpler models seen in Poser 1 and Poser 2.  (Daz would later spin off from Zygote.)

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
