I have Poser 5 and the Victoria 3 base.

I'm trying to use some of the body morphs but many of the dials do nothing.  For example changing any of the PBMBreastSize1 - 8 dials do nothing while some of the other dials do work like the JCM ones.  Almost all of the PBM dials dont appear to change anything on the model.  I did notice on Daz that there is a Victoria 3 Head and Body Morph item for sale.  Does this mean I have to buy this to use the dials I already see?  I've used Poser for awhile now but mainly for making animations.
