What is ZBrush and why it crashes while saving




ZBrush is a software developed by Pixologic that enables you to sculpt, paint, and texture virtual clay in a real-time environment. It has many features and benefits that make it the industry standard for digital sculpting, such as:


  • It can handle millions of polygons with little to no lag or slowdown.



  • It has a variety of customizable brushes, alphas, and tools to achieve any desired effect.



  • It has a unique system of layers, masks, and polygroups to organize and edit your model.



  • It has a powerful rendering engine that can create realistic images and animations.



  • It has a flexible workflow that supports multiple file formats and integrates with other software.



However, despite its advantages, ZBrush is not perfect. It may crash while saving due to various reasons, such as:


  • Your computer does not meet the minimum system requirements for ZBrush.



  • Your preferences or settings are not optimized for your system or project.



  • Your ZBrush version or plugins are outdated or incompatible.



  • Your model or project is too complex or corrupted.



  • Your disk space or memory is insufficient or fragmented.



How to prevent ZBrush from crashing while saving




The best way to avoid losing your work due to ZBrush crashing while saving is to prevent it from happening in the first place. Here are some tips and tricks that can help you save your work safely and efficiently:


Use Tool Save As instead of Project Save As




One of the most common mistakes that cause ZBrush to crash while saving is using the wrong save option. There are two ways to save your work in ZBrush: Tool Save As and Project Save As. The difference between them is that Tool Save As only saves the currently selected tool (or subtool), while Project Save As saves everything in the scene, including lights, materials, render settings, etc. The latter option is more prone to crashing because it involves more data and processes. Therefore, it is recommended that you use Tool Save As as much as possible, especially if you have a large or complex model. You can access this option by going to Tool > Save As or pressing Ctrl+Shift+S. You can also assign a hotkey to it for convenience.


Use SubTool Master plugin to save multiple subtools




If you have a model that consists of multiple subtools, you may want to save them all at once instead of individually. However, using Project Save As may not be the best option for this, as explained above. A better alternative is to use the SubTool Master plugin, which is included in ZBrush by default. This plugin allows you to perform various actions on all or selected subtools, such as saving, loading, merging, duplicating, renaming, etc. You can access this plugin by going to ZPlugin > SubTool Master or pressing Ctrl+Shift+X. To save all your subtools, simply click on the Save button and choose a destination folder and file name. You can also choose to save each subtool as a separate file or as a single file with multiple tools.


Use ZRepeatIt plugin to automate saving process




Another useful plugin that can help you prevent ZBrush from crashing while saving is ZRepeatIt, which is also included in ZBrush by default. This plugin allows you to record and repeat any action or sequence of actions in ZBrush, such as saving, exporting, rendering, etc. You can access this plugin by going to ZPlugin > ZRepeatIt or pressing Ctrl+Shift+R. To use this plugin to automate your saving process, follow these steps:


  • Click on the Record button and perform the action or sequence of actions that you want to repeat, such as Tool Save As or SubTool Master Save.



  • Click on the Stop button to stop recording.



  • Click on the Repeat button to repeat the recorded action or sequence of actions.



  • Optionally, you can click on the Repeat Every button and enter a time interval (in seconds) to repeat the action or sequence of actions automatically every specified time.



This way, you can save your work periodically without interrupting your workflow or risking a crash.


Export your model as FBX or OBJ file




A final tip to prevent ZBrush from crashing while saving is to export your model as a different file format, such as FBX or OBJ. These formats are more universal and compatible with other software, and they may be more stable and reliable than ZBrush's native formats. However, they may also lose some information or features that are specific to ZBrush, such as polypaint, layers, masks, etc. Therefore, you should only use this option as a backup or for transferring your model to another software. You can export your model as FBX or OBJ by going to Tool > Export or pressing Ctrl+E. You can also use the FBX Export Import plugin (included in ZBrush by default) to export or import multiple subtools as FBX files.


How to recover your work after ZBrush crashes while saving




If you are unlucky enough to experience a crash while saving in ZBrush, don't panic. There may be some ways to recover your work and resume your project. Here are some methods that can help you restore your work after a crash:


Use QuickSave files in Lightbox




ZBrush has a feature called QuickSave that automatically saves your work every few minutes (by default, every 20 minutes) in a temporary folder. You can access these files by going to Lightbox (pressing comma) and clicking on the QuickSave tab. You will see a list of thumbnails of your recent projects with timestamps. You can double-click on any thumbnail to load it into ZBrush. You can also change the frequency and location of QuickSave files in Preferences > QuickSave.


Use ZProject files in Lightbox




ZBrush also has a feature called ZProject that allows you to save your entire scene as a single file that includes all the tools, materials, lights, render settings, etc. This is similar to Project Save As, but it does not save any undo history or layers. Therefore, it is faster and more stable than Project Save As. You can access this feature by going to File > Save As ZProject or pressing Ctrl+Shift+P. You can also load any ZProject file by going to Lightbox and clicking on the Project tab. You will see a list of thumbnails of your saved projects with names. You can double-click on any thumbnail to load it into ZBrush.


Use AutoRecover files in Preferences




ZBrush also has a feature called AutoRecover that automatically saves a backup copy of your current tool every few minutes (by default, every 10 minutes) in a hidden folder. You can access these files by going to Preferences > AutoRecover and clicking on the Recover Last Session button. This will load the last saved tool into ZBrush. You can also change the frequency and location of AutoRecover files in Preferences > AutoRecover.


How to troubleshoot ZBrush save crash issue




If none of the above methods work for you, or if you want to prevent the issue from happening again, you may need to troubleshoot the problem and find out what is causing it. Here are some steps that you can take to troubleshoot the ZBrush save crash issue:


Check your system requirements and preferences




The first thing you should do is to make sure that your computer meets the minimum system requirements for ZBrush. You can check the official system requirements here: . If your system does not meet the requirements, you may need to upgrade your hardware or use a different computer. If your system meets the requirements, you should also check your preferences and settings in ZBrush. You can access them by going to Preferences > Config. Some of the preferences that may affect your saving performance are:


  • Mem: This controls how much memory ZBrush can use. You should set it to a value that is lower than your available RAM, but high enough to handle your project.



  • Compact Mem: This controls when ZBrush will compact the memory to free up space. You should set it to a value that is lower than your Mem value, but high enough to avoid frequent compaction.



  • MaxPolyPerMesh: This controls the maximum number of polygons that ZBrush can display per mesh. You should set it to a value that is lower than your system's limit, but high enough to maintain your model's quality.



  • MultiDraw: This controls whether ZBrush will use multiple threads to draw the screen. You should enable this option if you have a multi-core processor, but disable it if you have a single-core processor.



You can also restore the default preferences by clicking on the Restore Standard button in Preferences > Config.


Update your ZBrush version and plugins




The next thing you should do is to make sure that you have the latest version of ZBrush and its plugins. You can check for updates by going to ZPlugin > Auto Update or by visiting the official website: . Updating your ZBrush version and plugins may fix some bugs or compatibility issues that cause the save crash issue. You should also uninstall or disable any third-party plugins that are not compatible with your ZBrush version or that may interfere with the saving process.


Contact ZBrush support or community forums




The last thing you should do is to contact ZBrush support or community forums for further assistance. You can contact ZBrush support by submitting a ticket here: . You can also join the community forums here: . There, you can ask for help from other users or experts, share your problem and solution, or report any bugs or feedback. You may need to provide some information about your system, ZBrush version, model, project, error message, etc. to help them diagnose and solve the issue.
