if you look at that pic, the spanki figure has folds at the waist that v3 never does.  everything i've seen and read has pointed to spanki creating a unique, non-daz based character with an emphasis on realistic joints and bending.  but maybe i misunderstood.

edited to add: in fact, the caption of the picture says:
"Figure modelled, grouped and UV-mapped in Cinema 4D, rigged in Poser, textured by Fatale and [spanki]."

so not v3.
