Well we’ve got legacy shapes for Steph 3 and Steph 4 for Genesis, already. My own take on it is that each of the new DAZ figures is adding another group of morph targets, and ways to combine them to the collection, rather than just one new shape. Or, in other words, rather than just giving us a new (dialable) character preset, it’s giving us a new set of dials to build our own new characters from. Steph 5 comes with a base figure porportioned to be shorter, with three varying builds, and at least a couple of new faces. We didn’t have those *particular* dials in our parameters tab before. Although we might have been able to get fairly close with the ones we did have.
Plus, it gives DAZ an excuse to roll out a new group of hairs, skins, outfits, and pose packs all at once.
