I'm mildly curious about this: I'm picking up that there are those who feel strongly that Poser users should be upset/annoyed/dismayed/some-other-unhappy-sentiment because of their chosen software's inability to support another software's figure and the technology that figure represents. This appears to be the message of the OP and several other posters.

Those posters are contrasted by enthusiastic Poser users (with a few exceptions) who are clearly saying they're quite happy not being able to use those figures. That doesn't seem to please those other-technology proponents, who seem to want Poser users to demand to their software developer that Poser be able to use this other software's figure and incorporate the technology necessary for those figures into Poser. Enthusiastic Poser users counter with the statement that they perfectly content that Smith Micro has decided to focus on weight-mapping and better, more sophisticated materials, but that doesn't seem to satisfy those intent on making Poser users want/need these competitive/incompatible figures.
Which, frustratingly enough to those individuals, doesn't seem to be happening.

It's always those same people, too. You can pretty much predict what will be said.

I'm working in Blender 2.63. Jeez, if I were going to proselitise, caustics, node-based glass with an IOR channel, real-time preview rendering, materials that boggle the mind. Blender knocks the socks off what I'm rendering in Poser. But, I'm leaving it alone. I'll just use Blender for what it does best.

We Poser-users already have figures galore. You want more? Have a look at what Turbo-Squid has to offer and ask Smith Micro for SubD in the next version of Poser. Don't limit yourselves. Do think outside of the content-creator-as-standard-setter box.

There is some awesome stuff out there. And more on the way.
