Zetta is an amazing character for Victoria 7 for use in Daz Studio 4.8 and up. While she looks best with Victoria 7, her skins were made on Genesis 3 Base UV, so you can use her even if you do not own Victoria 7. However, her morphs will just not look exactly the same. She also comes with a Stylized body and head morph, that requires Aiko 7, if you want to use it.
The head for Zetta is uniquely custom sculpted in Zbrush and has added dials for extra details, and the skin was created using high quality photo references for depth and detail. In addition to photos, she also has hand painted details.
Her face is soft and feminine and her body is sensual and muscular, allowing for her to be perfect for your creative needs.
