Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\Pixologic\ZBrush 2024\ZBrush.exe or C:\Program Files (x86)\Pixologic\ZBrush 2024\ZBrush.exe
Warning
Many processes normal
ZBrush uses multiple internal threads and can spike CPU/memory during dense sculpting, GoZ transfers, or dynamesh operations
Can I Disable?
✔ YES
Close ZBrush when not in use; to stop startup, disable it in Task Manager > Startup; adjust background GoZ settings if needed
What is zbrush.exe?
zbrush.exe is the main executable for Pixologic ZBrush, the professional digital sculpting and painting application. It launches the sculpting workspace, loads brushes, Dynamesh, SubTools, textures, and the GoZ bridge for interoperability with other 3D apps. It coordinates rendering, tool pipelines, and export tasks as you model.
zbrush.exe runs as a multi-threaded process that handles the UI, sculpting math, dynamic tessellation, and viewport rendering. It communicates with GPU drivers for shading, brush displacement, and manages GoZ/export pipelines to external software.
Quick Fact: ZBrush pioneered robust multi-threaded sculpting with GoZ interoperability, enabling large, detailed models with responsive brushes.
Types of ZBrush Processes
- Main UI Process: Controls the user interface, brush palette, and tool settings (1 instance)
- GoZ Bridge Process: Handles data transfer to external apps like Maya, 3ds Max, Blender
- Viewport Rendering: GPU-accelerated shading and live preview of sculpted meshes
- Dynamesh/Remeshing: Dynamic tessellation and remeshing during sculpting sessions
- SubTool / Export Helpers: Manages SubTools, textures, and export pipelines (OBJ/FBX)
- Utility/Background Tasks: Autosave, backup, and plugin initializations
Is zbrush.exe Safe?
Yes, zbrush.exe is safe when it's the legitimate file from Pixologic downloaded from pixologic.com or installed via a trusted installer.
Is zbrush.exe a Virus or Malware?
The real zbrush.exe is NOT a virus. However, malware sometimes disguises itself with similar names. Always verify location and signature.
How to Tell if zbrush.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\Pixologic\ZBrush 2024\ZBrush.exe or C:\Program Files (x86)\Pixologic\ZBrush 2024\ZBrush.exe. Any other path is suspicious.
- Digital Signature: Right-click ZBrush.exe -> Properties -> Digital Signatures. Should show signer as Pixologic, Inc.
- Resource Usage: Normal startup uses modest CPU and memory. Abnormal, constant spikes when idle are suspicious.
- Behavior: ZBrush should run when you start the program. Multiple hidden instances or background activity without launching ZBrush is a red flag.
Red Flags: If zbrush.exe appears in unusual folders (Temp, AppData, or System32), runs when ZBrush isn't open, lacks a valid digital signature, or uses resources constantly, scan with antivirus software immediately. Be wary of similarly named files.
Why Is zbrush.exe Running on My PC?
zbrush.exe runs when you start Pixologic ZBrush or when certain features and background tasks are active, such as GoZ transfers, autosave, or live sculpting sessions.
Reasons it's running:
- Active Sculpting Session: You're actively sculpting; brush calculations, dynamic tessellation, and viewport updates run in real time, consuming CPU/GPU resources.
- GoZ and Inter-Application Workflows: GoZ connections with Maya, 3ds Max, or Blender can spawn processes or threads to transfer geometry and textures in the background.
- Autosave and Recovery: ZBrush periodically saves your work to protect changes, which may briefly spike disk I/O and memory usage.
- Plugin and Tool Initialization: Installed plugins or custom brushes initialize on startup or project load, contributing to initial CPU/memory load.
- Export/Render Preparations: Preparing large exports (OBJ/FBX textures) or viewport renders can temporarily increase resource use.
Can I Disable or Remove zbrush.exe?
Yes, you can disable zbrush.exe. Exiting ZBrush stops the main process; you can uninstall ZBrush via the Pixologic installer or Windows Settings if you no longer need it.
How to Stop zbrush.exe
- End Active Session: Save your work and close ZBrush using File > Exit or the window close button
- Close Background Tasks: In ZBrush, disable nonessential background features like autosave if available
- Disable Startup: Task Manager > Startup tab > Disable Pixologic ZBrush
- End Processes: Open Task Manager (Ctrl+Shift+Esc), locate zbrush.exe, and End Task
- Stop GoZ Transits: In ZBrush preferences, disable or remove GoZ connections to other apps
How to Uninstall ZBrush
- ✔ Windows Settings → Apps → Apps & Features → Pixologic ZBrush → Uninstall
- ✔ Run the Pixologic installer again and choose Uninstall, or use the dedicated uninstaller provided by Pixologic
- ✔ Optionally remove leftover user data from C:\Users\<YourUser>\Documents\ZBrush, and consider reinstalling if you plan to re‑install later
Common Problems: High CPU or Memory Usage
If zbrush.exe is consuming excessive resources during sculpting or exporting:
Common Causes & Solutions
- Too many active SubTools or extremely dense meshes: Reduce SubTools, use Merge Visible, or decimate meshes with Decimation Master before heavy editing
- Heavy Dynamesh or ZRemesher operations: Lower resolution for Dynamesh, or perform remesh with smaller targets; increase RAM if possible
- Resource-heavy brushes or textures: Disable unnecessary brushes/textures; use smaller brush sizes and lower texture resolutions during initial sculpt
- Outdated GPU drivers: Update graphics drivers from the GPU vendor (NVIDIA/AMD) to support ZBrush viewport shading
- Background GoZ transfers: Pause or disable GoZ when not actively transferring data to other apps
- Background autosave: If available, adjust autosave frequency or temporarily disable autosave during heavy sessions
Quick Fixes:
1. Use Shift+Click or the GoZ panel to identify heavy tools and SubTools
2. Close unused SubTools, then save and restart ZBrush
3. Update ZBrush to the latest patch
4. Lower Dynamesh resolution and disable unnecessary textures
5. Check Task Manager for background processes and end unneeded ones
Frequently Asked Questions
Is zbrush.exe a virus?
No, the legitimate zbrush.exe from Pixologic is not a virus. Verify the file is located in C:\Program Files\Pixologic\ZBrush 2024\ZBrush.exe and has a digital signature from Pixologic, Inc.
Why is zbrush.exe using so much CPU?
High CPU usage typically happens during dense sculpting, GoZ transfers, or when Dynamesh/Remeshing is active. Identify the heavy task in the UI or Task Manager, then optimize the scene or pause those features.
Can I delete zbrush.exe?
Yes, you can uninstall ZBrush via Windows Settings or the Pixologic installer. Your projects and preferences may remain in your user folder unless you delete them separately.
Can I disable zbrush.exe?
Yes. Close ZBrush to stop the main process; disable startup in Task Manager if you don’t want ZBrush launching automatically; disable or adjust GoZ and background tasks as needed.
Why does ZBrush start at startup?
ZBrush normally does not auto-start; if it does, it may be due to a launcher or a startup script. Disable that entry in Task Manager > Startup or in the Pixologic launcher settings.
How can I reduce ZBrush's memory usage?
Work with fewer SubTools, use Decimation Master for heavy meshes, optimize Dynamesh settings, and consider closing other applications to free up RAM.
