"...to give you a more versatile
mesh."

This is exactly DAZ went wrong: Versatility is the worst thing their marketing department came ever up with.
"Buy one figure and dial her into a gazillion shapes !"

Sorry, but "Jack of all trades but master of none" is not good enough.

If you want true realism and accuracy, then we need specialized figures.
I want a mesh that looks as convincingly "FAT" as Rikishi does because it was built as a FAT person from the ground up. with joints especially made for a FAT person and JCM's especially made for a FAT person.
Not a "morphform" that makes the joints break.

And I also want a realistic THIN person where you can count every rib and see every muscle under the skin.

And also realistic children which really look like children and not like little shrunken adults.
I want women that look like women and men that look like men.
And realistic proportions, not carricatures like you find these days on the photoshopped titles of fashion mags.

I'm sick of the "generic blank canvas stuff".
Actually "I" can morph and re-rig any mesh so that it fills my needs, but how many people can ?
And how many people who can, do ?

In all these years Blackhearteds Irina and GND where the only attempts to create a more realistic body for V3 and SP3.
And I won't be surprised if his new GND4 will stay the only attempt for V4.

Sorry, but the majority uses a figure "as is".
So we need meshes that are specific and photorealistic right out of the box.

The "blank canvas" idea has failed because hardly anybody in Poserdom is able to fill it.
And no, spinning the same lame old four body dials to make the boobs bigger doesn't count.

Let toons and anime be toons and anime, and let realistic be realistic.
Don't mix them up.
Don't "design" figures so that the "might" sell better.

Just copy reality.

Jeeez. I guess if someone could persuade Milla Jovovich to let herself scanned in a 3D scanner and then make an EXACT 3D clone of her, exact and accurate to the last fraction of an inch, a lot of folks here would start to whine and wail and gnash their teeth and insist that she'd be way too ugly to sell even a single copy because her ass might be too fat, her legs too short and her boobs too small.

In the scale modelling world people will tear you apart if you forget to replicate a single rivet or a welding bead on a model.
But among 3d modellers, and especially in Poserland,  accuracy seems to be quite "optional".
