Regardless of your artistic level, we are confident ZBrush 4R2 will embrace your creative needs.
We are thrilled with this release, and eager to see the benefits that you will gain from what ZBrush 4R2 offers.
In the upcoming months we will continue the development of those features towards the release of ZBrush 5.
ZBrush 5 will include new features as well as 64 bit versions of ZBrush for Mac and Windows operating systems.
Special thanks to all those involved in the making of ZBrush 4R2, including: the beta team, artists, ZBrushCentral members, and the staff at Pixologic around the world.
