Lots of free, professional 3D software for free on the DAZ homepage, apparently for a limited time only. Be aware though, if you’re running a Mac with OS X Lion installed, Bryce and Hexagon won’t work as far as I’m aware. But Studio with the included Genesis figure is incredible. Simply incredible.
Here’s a quick render I did today with Michael 4 (free) and the Anatomy Bundle ($). Took me all in all about 2 hours – the most complicated part was getting the render settings right.
Many tutorials can be found on YouTube.
