ZBrush 4R7 is available in two separate applications:
- The official release 4R7 application, which is a 32-bit program.
- A second executable, the 4R7 64-bit Preview.
While an official 64-bit release will have to wait for ZBrush 5 due to the complex nature of this migration, we are providing 64-bit version of 4R7 as a “developer preview” of this update which you are welcome to use as you wish. This preview edition has exactly the same features as the official 32-bit release and has been tested on a wide variety of systems. However, there is no substitute for real-world testing by thousands of artists. In order to guarantee that no problems arise as part of the transition to 64-bit coding – especially for those of you who are using ZBrush for mission-critical projects! – we will continue to treat the 32-bit version as the official release until ZBrush 5, at which point ZBrush will exclusively be available as a 64-bit application.
Feel free to use the 64-bit Preview today! You will find it already installed in your ZBrush 4R7 folder, next to the 32-bit version. It is already faster than the 32-bit version and of course you can push ZBrush to the limits of your computer’s RAM and processing capabilities! But at the same time, rest assured that in the unlikely event that an issue is encountered you will still have the trusty reliability of the 32-bit version to fall back on.
