Baking Error: sqlite3.OperationalError: attempt to write a readonly database about blender-flip-fluids HOT 5 OPEN

Hi, thanks for the report and files!

I was not able to reproduce the issue on our systems, but we did had another similar report of a database error in the past, although a different error message (issue #530). Unfortunately this issue went unsolved and we did not gain feedback for solving the issue.

Would you be able try these troubleshooting steps which may help us better understand what may be the cause of this issue:

• Try restarting your system (unless this has already been tested).
• Manually delete the cache directory (C:\Users\User\Desktop\d\T-72bugReport) and try again. Does the export seem to continue without issues?
• Set the cache directory to another location on your system. The current location is within the user Desktop. Test another location such as within the user Documents directory just in case there are any permission errors within the Desktop. Does the export seem to continue without issues?
• If the above did not work, would you be able to test the issue resetting Blender's userdata? This will eliminate issues related to corrupt userdata. The userdata can be reset renaming the Blender userdata folder from:
  • C:\Users\User\AppData\Roaming\Blender Foundation\Blender\3.5
  • rename to C:\Users\User\AppData\Roaming\Blender Foundation\Blender\3.5_backup
  • Restart Blender, install addon, and test again.
  • For full instructions and how to restore back the original userdata, see this topic: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Baking-Crash-Troubleshooting#testing-the-flip-fluids-addon-in-a-clean-installation-of-blender

Let us know if you have any questions or if you find any more information about the issue.

Setting the cache directory to roaming seems to semi fix it it happends less know all dough it still happends but somewhat rarely now

Thanks for the update. Ideally, this should not happen at all.

Something else to try could be to test exporting after disabling any antivirus software if that is relevant. It could be possible that an antivirus program is temporarily marking the database file as 'read-only' and triggering the error. This is something we had encountered in a similar issue in the past with another artist and the solution was to add a folder to the antivirus whitelist.

Let us know if you have any questions or if you find any more information about the issue.

I'm not aware of any antivirus software going through that folder; there's a windows machine connected to the share though, with standard windows defender on.

Thanks for the info! The shared location could be a possible explanation for this type of error and possibly also issue #530. The simulation cache should not be located on a shared location during baking (cache directory notes). The simulator requires modifying files in the cache and sometimes shared locations can end up locking files and preventing the addon from making file changes.

It is okay to move the cache to a shared location after baking. Rendering the cache require only reading the files.
