Poser 4 nude has alot more mapping options, the geometry is about the same as Poser 3 nudes, but they are mapped better. Eve is a good high quality anatomically correct free nude, and the Eve Version 3, which incidentally requires download and installation of regular Eve may be easier for you to work with on the texture end of things. I reposted the old P4WWG last week, another anatomically correct Poser4 nude, as well as my Ayesha. Both are high quality. Ayesha comes also with props, textures, poses, etc, since learning to pose either Eve, P4WWG, Ayesha, or the new Vicki can be a learning curve. I believe Eve and P4WWG is the future of where the free models are going. Now on the pay to play side of things, there is Vicki. Excellent model, but be prepared to feel cheated when you take her out of the box so to speak. She does take a bit of adjustments and work to bring out the beauty in. She is where the future of pay to play is going.
