Well, if we go by the "That pose is only used for porn..." argument, we could have just as well stopped at Poser 4 rigging.

Because for your average "look at me how pretty I am" render Posette and the Dork are rigged perfectly well enough.

But to me good rigging means of course "Can convincingly do the full range of poses achieveable by a healthy human being".

Doesn't matter if you can do it, or I can do it, as long as someone can do it in real life, I want my Poser people to be able to do it, too.

And, btw, non-exploding butts are also a big help with Yoga poses or martial art poses or generally any action pose that involves leg movement and is supposed to look natural.

Especially as a lot of Poser clothing is skin tight.

An exploding butt is just sloppy rigging, not an anti-porn statement.

I'm all for Genesis, but only because there is currently nothing better around.
