Hi,
Do you mean the parameters set in the Export dialog? Yes, when back to the main window, if you save the current config, they will be saved in the default ini file (~/.rtabmap/rtabmap.ini). They are under [Gui]->ExportCloudsDialog section.
Just found that when opening Preferences and clicking on Save settings, the ExportCloudsDialog settings are not stored in the ini file. I opened an
issue.
cheers,
Mathieu
