LOL, I did download Blender, examined it for a week with Excedrin and coffee, and deleted it.  Same with Truespace, deleted it.

Making human models from scratch via Maya, etc, went to Books-a-Million sought out a book on Maya, examined it and quietly placed it back on the shelf.  

ZBrush, haven't seen a book on  that one yet, saw a tut in 3D World Magazine  looks similiar to one of my Calculus courses, also quietly opened another page on something else.

Bottom line, until I can do better, I'm not critizing any model built by the talents at SM or DAZ.
Like I stated before, I can flip dials on both to make my dream girls.

Yep Wespose, it tain't all that easy.  Jan
