As the makers of Zbrush, Pixlogic has released a free and easy to use 3D sculpting software named Sculptris. Sculptris is basically a stripped down version of Zbrush but it has enough options and flexibility to make is useful and a joy to use.  The interface is nicely designed and even the most novice computer user would feel comfortable with creating sculpts in no time. Starting out with a round ball of clay or an imported OBJ model Scuptris allows you to push, pull, and manipulate objects like clay in the real world. Sculptris also has 3D painting, texturing, Auto UV mapping and material options. Just in case that’s not enough there is a GoZ option which seamlessly lets you use Zbrush in conjuction with Sculptris.
