About the names of the models in Daz: In the beginning was Poser. It created daz site only to sell stuff for Poser. The first models for Poser were called Millennium. There were 4 generations millennium models. The first 2 generations are long dead, you can find very rarely something from 3rd generations, and there are still lot of items for the 4th generation incl for the updated version 4.2. The millennium models are usually marked as V4 (V4.2) and M4 (from Victoria and Michael I guess). Then Daz decided to make own models and thus started the Genesis line. There are 3 generations of genesis - G1, G2 and G3. As You can presume the G1 is defunct, but there are still a lot of items for G2, as well as a lot of scripts or direct adjustments of the clothes and such to be able to work with G3 too (but this is not guaranteed). Also the later version of the Daz Studio include so called "Clones" of the older models which on theory should allow the stuff for older versions starting from V4 (M4) to be able to use the "auto-fit" function for use with G3 (but again this is not guaranteed). And at last because many users were frustrated and were protesting, when the new model appeared, Daz decided to unify the whole model line, so the Millennium models started from Genesis 1, G3 respectively became G7 and the newest model became Genesis 8. Still, for the purpose of compatibility with the older stuff, nowadays largely is used the next naming convention: If you are using the name of the models they are V4, V5, V6, V7 and V8 (from Victoria) and respectively M line from Michael. At the same time if you don't name a certain model but the whole generation, you still use Genesis 2, Genesis 3 and Genesis 8. So if you read in the description of some product "morphs for Victoria 7 and Genesis 3 females" (for example) this means those morphs are tested on Victoria 7 and the basic Genesis 3 female model and should work with *ALL* the Genesis 3 based models *IF* they are not grossly deformed (enlarged, reduced etc). It is the same with V8 and G8 females, as well with the M7 and M8 and G8 females and G8 males; also there are some product which are marked to work both with G3 females and G3 males *or* G3 females and G8 females or even with all the 4 models (G3M, G3F, G8M, G8F).
