So that newcomers can be introduced  into the 3D market without having to waste money learning how...I'm very grateful to Daz Studio for  that reason...Poser and Carrara and other paid for apps cost a lot to find out you can't manage and it's not for you..At least with DS you haven't wasted any money amd you have learned some basics BEFORE you get your hard won currency out to BUY 3D software..
