ZBrush 4R7 is the final iteration within the ZBrush 4 series before its developer Pixologic moves on to ZBrush 5.0. The newest release contains many major additions and is said to be one of the most extensive releases since ZBrush 4 came out. Signature features in ZBrush 4R7 include: ArrayMesh, NanoMesh and ZModeler with QMesh. All of these features are useful throughout the creative process, from initial creation of your model to the final touches. They also allow you to stay within ZBrush for more of your workflow instead of exporting to other apps. Beyond its feature set, the core of ZBrush is being reworked, and 4R7 will be the first version of ZBrush that is released with optional 64-bit support. You can now take more advantage of  your computing power for higher polygon counts at faster speeds.
