The autoupdate setting is kept in the registry under HKEY_CURRENT_USER\Software\Next Limit Technologies\Maxwell Render\LWIntegration\AutoUpdateCheck. You can disable it by importing a .reg file which sets the value to 0 (like this
, for example) or by running this command:
reg add "HKCU\Software\Next Limit Technologies\Maxwell Render\LWIntegration" /v AutoUpdateCheck /d 0 /f
This has to be done on each render node.
We have looked into skipping the update check when LW runs in command line mode, but we couldn't find a way to detect this condition so far.
