If you're so unhappy with Poser, then change to D|S or buy yourself a copy of a real 3d app like MAX and learn how to rig with weightmapps.

There ARE lots of things "wrong" with Poser that I'd love to see reworked, but Poser 7 is better than ever and with the addition of the seminal MorphBrush technology it's pose engine can already see eye-to eye- with anything you can do with weightmapping.

You just have to know what you're doing and don't use poorly rigged meshes like V4 or the G2 series as a benchmark.

I don't want a "re-write" from the "ground up" if this means that all previous content will become obsolete.
Get rid of bugs, improve functionality, get it more stable, I'm all for that.
And yeah, a FAST but still high quality render engine wouldn't hurt.

But NO to a shiny new "modernistic" GUI like almost every other 3d app on the planet has.
If you want Poser too look like MAX, then USE MAX.
And especially a big NO to weightmapping.
MAX and MAYA and others already can do this perfectlywell  so use THEM if you must

As for the rooms, no, I don't use the hair room or face room often.
But others do.
And I use the SetUp room almost daily because I almost never use premade content "as is".
And I use the cloth room for dynamic clothing, for modelling (!), and to add morphs to conforming clothes.

Finally, Poser will NEVER be taken "seriously" by professionals.
Forget that little dream of getting the big boys to "respect" you as a Poser user !
Studios want their own exclusive content, not paying royalties for some lame "EULA protected" DAZ or Poser characters any Dick, Jane and Harry can get for $1.99.
And professional 3d artists are expected to be able to create any type of content by themselves from scratch, not just move virtual Barbie dolls around with the  help of premade pose sets.

And it's not so much that Poser as a tool is looked down at, it's the people that predominantly use it.
So, unless you tell all those hobbyist Poser users to please take a hike so that Poser can get a better "image", all those rooting for a "more professional" Poser is a waste of time.
