I suppose someone could design a set of scalings to make the Poser adults child-size, and slave them all to a master full-body morph, which would be applied to varying amounts to produce a child of various ages; but that would have bugs:- (1) When a morph is slaved, the model name in the slaving description lines is not altered if the name of the model that it points to is altered. That caused trubble when someone with Poser 4 wanted a skinny elf-girl and a big heavy man in the same picture :: either the man went skinny, or the elf looked like someone from "On the Waterfront". (2) Scaling the Poser Nude Man to child size in this way would not lose the muscle bulges, and you would end up with "junior stevedore" instead of a usual child. Similarly with the Poser Nude Woman's chest. (3) I suppose someone could do the reverse and scale the Poser Nude Child to adult size and proportions. The result may well look like the skinny men with no muscles worth the name that you can see all over sunbathing beaches in the summer :-)
