The package includes some content for Daz Studio 4.8 and higher. Six base morphs for the Victoria 4 morphs and the Genesis 2 morphs.
There are separate morphs for the head and the body as well now. So you can use e.g. a V4 head morph with Gen2 body morphs on your Genesis 3 female figure.
The morphing tool can convert morphs made for Daz Victoria 4 or Genesis 2 to Genesis3 exporting from and importing into Daz Studio.
It supports V4 poser morph export and Daz Studio import for Genesis 3. Genes 2 poser morph export is not supported.
