You know actually I do have a question about this?

When I see that others have created different-looking V3 (or whatever) characters and giving them different names - are they doing that in Daz3d or are they doing that in the Poser program.

When using Daz3d If I take a basic V3 model and change things on her like her body parts, etc and the coloring - is it possible to save that character and then - say - upload it as a new character the way everyone else has been doing it?  And then someone being able to download it and use it in DazStudio?
