Frankly, I'm not surprised. Daz3D community's myopia is quite evident when I got on their forums and started asking material-based questions. It's their way or no way.

Perhaps this isn't a bad thing. Much as I look forward to the - at this point vaporware - Victoria 5, if she's going to be designed not to work in Poser or to only work in DS, Poser developers may be inclined to provide a bit of more sophisticated competition to the Poser-content people, as well as sky-rocket the Antonias of Poserdom to a highly prominent position.

What a MASSIVELY bad design decision, though. I'm guessing here, but based on the galleries and the marketplace I'd say that V4 holds supreme status as most popular figure. That said: I really don't see people ash-canning investments in Poser 8 and PoserPro2010 and defecting to DS over a figure.

And then, there's some other concepts I hate to even broach, but beg utterance: what's to keep really clever riggers to take the mesh of these Daz-only figures and re-rig for Poser compatibility?
