Better morph targets, Uv mapping (This is key -- as a good mapping and a good texture map can make or break a figure) I believe the Joint params are a bit better too (I may be wrong tho) Tho the 2 figures very close -- if not exact, just upgrading to Poser 4 was what did it for me. All the extras in Poser 4 is the important thing. I'll also stress that Mapping is Paramount! Zygote's Victoria has the absolute best mapping yet! No more blurring and smudging of the textures around curves. i.e. chin area/side. of head. Hope this helps. James
