Not only is DAZ Studio 3 free but, as of a few days ago, all DAZ’s 3D human base models are also free. Very useful human-figure reference software for comics artists and figurative painters, although if you want the DAZ domestic animals (cats, dogs, etc) you still have to buy them.
All DAZ 3D human base models are now free
