Nearly every user has the Daz 3D Body Morphs packages for their figures. Why not give it added functionality with Body Mixer. This add-on allows you to split up the iconic shapes into upper and lower areas from which you can control the strengths to your liking. You can also remove or exaggerate the shape details for the upper and lower areas, mix and match them with other shapes as well. As a bonus it also includes bend correction JCM's for the Portly and Heavy body shapes.
This product may be used for selling characters provided the Daz Body morphs as well as this package are required items.
