Its more like Mudbox..
I have played with mudbox as I hold a licence for all 2011 autodesk products. What I found was that with all of these sculpting programs is that you need a good graphics tablet to make good use of them. In all honesty I have seen some superb work done with this stuff. The best way to date I have seen is to make your basic geometry in your usual 3d program, then import into your sculpting program to add detail. then project a normal map onto your lower poly model.
But for film, and game animated sequences such a great piece of kit. Good find Bonk, was not aware of this particular software.
For now, I have just invested in an IPAD and paid for the sketchbook app, so an expensive graphics tablet will have to wait.
