ZBrush is a digital sculpting tool that combines 3D/2.5D modeling, texturing and painting. It uses a proprietary "pixol" technology which stores lighting, color, material, and depth information for all objects on the screen. The main difference between ZBrush and more traditional modeling packages is that it is more akin to sculpting.
Building meshes, extruding polygons and other 3D modeling tasks are single-threaded, meaning they only utilize one CPU core. If using this software mostly for modeling, we recommend a 4- to 6-core processor with a high clockspeed (3.2GHz and above).
Like 3D modeling, animation is also single-threaded. Therefore a processor with high clockspeed and 4 to 6 cores is also recommended.
While 3D modeling and animation only utilize one CPU core, rendering is a highly multi-threaded task and therefore a high amount of CPU cores will provide better performance.
In general, 3-6GB of RAM per CPU core is recommended. For example, if you select a single 12-core processor, 32GB will suffice for basic tasks or 64GB for more demanding workloads.
We recommend having two drives which provides the best performance:
- Primary Drive: SSD for the operating system and software
- Secondary Drive: another SSD, or for better performance, an NVMe Flash Storage Drive (the "HP Z Turbo Drive") for active project files
If you need additional storage for large, infrequently accessed files, we also recommend one or more 4TB, 6TB or 8TB+ hard drives. Hard drives also work well for storing export files as the export/rendering process is generally not write intensive.
This application has minor benefits from GPU acceleration, so a high-end graphics card is not required. Therefore, we recommend a NVIDIA GeForce RTX 2060.
The HP Z8 G4 Workstation is recommended if you would like dual processors and/or multiple high performance graphics cards.
The HP Z6 G4 Workstation is recommended if you would like to start with a single high-end processor and single high-performance graphics card with the potential of upgrading in the future. With the Z6 G4, you can add a second matching processor and double the memory using the optional second processor riser. The power supply will also support two mid-range graphics cards.
The HP Z4 G4 Workstation is recommended for majority of workflows. Since Intel now produces single Core i9 and Xeon processors with up to 18-cores and high clock speed, there is no need for dual processors unless you will have heavy CPU rendering or intensive tasks demanding more than 18-cores. Also, the HP Z4 G4 has an optional 1000W power supply that will support the most powerful graphics cards inluding the GeForce RTX 2080Ti and Quadro RTX 6000.
