The $100 HeadShop 12 plugin is “coming soon” for Poser 11. With its ‘Lovechild’ feature which seamlessly morphs between two photos, under the control of simple sliders, before producing the 3D head.
The blurb on the announcement page says the Poser version will work with “Poser LaBelle”. But I suspect that must be a translation error, and he actually means La Femme — which is Poser 11’s flagship female base figure.
HeadShop 12 is already available for DAZ Studio, at $100, and works with Genesis 2, 3 and 8.
