Quote - A practical question... are there things that can be done to a Poser figure to make sure that it can not be perceived as representing a minor? I used to use large breasts and plentiful pubic hair for my artistic nudes but I suppose in the United States only minor females have pubic hair these days! I have found myself forced to render female characters of virtual age 55 to 90 for nudes out of prudence in regards to these issues... are there ways to make a female figure clearly a virtual 20 or 25 say? I notice in commercials for KY lotion on TV the characters brandish wedding rings... would that help? Are there matters of morphology that would anchor a figure clearly in the 20 something age?

If it looks like a child, it's a child.  If there is some doubt then you had best put in secondary clues in the composition that can be clearly interpreted and which leads to viewer to immediately assume the character is an adult.  There should be no hesitation in making that assumption if you wish to do what's right.

If you still can't figure it out by then, you're doing it wrong.  There is a huge difference between a young minor and an adult.  That should be very clear.  There is somewhat less of a difference as age progresses to adulthood.  HOWEVER, if you're skirting around depicting "Just turned 18" types of figures, you should probably back off.

One thing you can probably do is spin the voluptuous dials, give the breasts a bit of fullness and gravity effects, make sure the hips are wide enough and make sure the limbs are not too long.  Then, email it to an attorney and ask them. :)
