Quote - What ever happened to the weight mapped G2 figures, especially Sydney?

I'd heard her mesh was a mess, did that bring about a cancellation of reworking her?

Her mesh is asymmetrical, which is not the same as a mess. Making the mesh symmetrical would break every morph & every character ever made for them.

As far as reworking her for weight mapping, anyone with Poser 2012 or 2014 can do that themselves.  In Poser 2014, the first 60 or so steps have been reduced to 1 step:

Figure - Merge all Zones to Weight Maps. 

After that, I don't know how much you know about the Joint editor, but if you follow along in chapter 33 of the 2014 manual (Working with Joints, Weights, and Skinning)

It isn't hard, but it can be tedious.
