If you have Victoria, trial and error might be your brest, sorry, best bet. There are "lay down" and "natural" morphs which help a lot. You're so right about graviy...too many Poser artists appear to be placing their ladies in zero-g, myself included sometimes. What helped me with this was studying other peoples' morph dial settings to see how they achieved realistic effects Some are quite complex, but yield real-looking bosoms. With practice you'll "get it." Pin up girls and the subject of realistic breasts "out of the loop?" Oh, no. I don't think so. :-)
