This may cause instabilities" ## Possible causes and solutions for getting an out-of-memory error ### Issue When trying to render you may receive the following error: Out of memory (requesting 4294967214 MB!!) This may cause instabilities... ![](https://support.keyshot.com/hs-fs/hubfs/image-png-Jun-20-2025-01-37-13-3946-PM.png?width=493&height=208&name=image-png-Jun-20-2025-01-37-13-3946-PM.png) ### Environment Details - KeyShot - Any versions ### Cause - Out of memory on the system for GPU memory - Too much geometry created with Geometry Nodes - Corrupted OptiX cache ### Workarond Please try the following solutions depending on your situation #### Solution 1 Try exporting the file type as a "PSD" file instead of a "PNG" file and see if that renders without errors. If this does not help, it might be caused by Geometry Nodes. #### Solution 2 Some Geometry Nodes might produce a lot of Geometry. You can limit the number of Curves in Millions in the Geometry Node's settings. ![](https://support.keyshot.com/hs-fs/hubfs/image-png-Jun-20-2025-12-03-29-0308-PM.png?width=362&height=95&name=image-png-Jun-20-2025-12-03-29-0308-PM.png) Please note that this is the setting per part, so if you have many parts with the respective material, you might need to reduce it further. You might need to open such a file in the Recovery Mode, which you can access by navigating to Help → Open (Recovery Mode) which opens the file in Performance Mode and without the Geometry Nodes being executed. ![](https://support.keyshot.com/hs-fs/hubfs/image-png-Jun-20-2025-12-05-33-0093-PM.png?width=222&height=258&name=image-png-Jun-20-2025-12-05-33-0093-PM.png) Some materials like the RealCloth when using the 3D Ply Geometry may also cause a tremendous amount of Curves being generated, depending on the object size and weave scale. Switching to the Single Sided or Two Sided display mode should resolve the issue. ![](https://support.keyshot.com/hs-fs/hubfs/image-png-Jun-20-2025-12-09-49-3187-PM.png?width=460&height=121&name=image-png-Jun-20-2025-12-09-49-3187-PM.png) #### Solution 3 Corrupted OptiX cache might cause this issue as well if it is happening even in fresh or simple scenes. In the Resource Folder you should see three files for the OptiX cache. Please close KeyShot, delete these files and relaunch it. ![](https://support.keyshot.com/hs-fs/hubfs/image-png-Jun-20-2025-12-11-56-7582-PM.png?width=245&height=215&name=image-png-Jun-20-2025-12-11-56-7582-PM.png) The Resource Folder is located in the following directories - Installed Just For Me: %UserProfile%\\Documents/KeyShot Studio or  C:\\Users\\\\\Documents\\KeyShot Studio - Installed For Everybody: C:\\Users\\Public\\Documents\\KeyShot  Studio or  %Public%\\Documents\\KeyShot Studio For older versions, replace Studio with the version number, e.g. KeyShot 12 for KeyShot 2023, KeyShot 11, etc. If that does not help, please back up your custom resources and perform a [fresh installation](https://support.keyshot.com/en/knowledge-base/how-to-do-a-fresh-install-of-keyshot?hsLang=en). ### Additional Resources - [Layers and Passes](https://manual.keyshot.com/manual/render-4/render-output/layers-and-passes/) - [How to do a Fresh Install of KeyShot](https://support.keyshot.com/en/knowledge-base/how-to-do-a-fresh-install-of-keyshot?hsLang=en) - [Technical Support](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#main-content) - [KeyShot Studio](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#keyshot-studio) - [Network Rendering](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#network-rendering) - [KeyVR](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#keyvr) - [Plugins](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#plugins) - [How-To](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#how-to) - [KeyShot Hub](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#keyshot-hub) - [KeyShot Web](https://support.keyshot.com/en/knowledge-base/technical-support?hsLang=en#keyshot-web) - [License Support](https://support.keyshot.com/en/knowledge-base/license-support?hsLang=en#main-content) - [Node-Lock](https://support.keyshot.com/en/knowledge-base/license-support?hsLang=en#node-lock) - [Floating](https://support.keyshot.com/en/knowledge-base/license-support?hsLang=en#floating) - [Subscription](https://support.keyshot.com/en/knowledge-base/license-support?hsLang=en#subscription) - [FAQs](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#main-content) - [General FAQs](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#general-faqs) - [Key VR](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#key-vr) - [KeyShot Studio FAQ's](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#keyshot-studio-faqs) - [KeyShot Web FAQ's](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#keyshot-web-faqs) - [KeyShot Network Rendering FAQ's](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#keyshot-network-rendering-faqs) - [KeyShot WebViewer](https://support.keyshot.com/en/knowledge-base/faqs?hsLang=en#keyshot-webviewer) - [Announcements](https://support.keyshot.com/en/knowledge-base/announcements?hsLang=en) - [Learning Content](https://support.keyshot.com/en/knowledge-base/learning-content?hsLang=en#main-content) - [Webinars](https://support.keyshot.com/en/knowledge-base/learning-content?hsLang=en#webinars) - [Quick Tips](https://support.keyshot.com/en/knowledge-base/learning-content?hsLang=en#quick-tips) - [Downloads](https://support.keyshot.com/en/knowledge-base/downloads?hsLang=en) - [Best Practices](https://support.keyshot.com/en/knowledge-base/best-practices?hsLang=en) [![Chill listening crop-3](https://support.keyshot.com/hs-fs/hubfs/keyshot-logo-blk-3d.png?width=63&height=24&name=keyshot-logo-blk-3d.png "Chill listening crop-3")](https://www.keyshot.com/) keyshot.com Help Center Copyright © 2026, KeyShot
