There are a lot of 3D modeling programs it is impossible to know them all. There are only two(2) Poser programs. Compared to 3ds max with its 5000 plugins Daz is a breeze to learn. The content providers have always know both programs.

Complaining over that you got something for free, great god! In the future, if you don't know both Daz and Poser don't talk to me I have better things to do.
