When configuring your project settings in Lustre, you can configure some parameters as project defaults and others as user defaults. The parameters that are configurable as project defaults become the default settings each time a project is loaded, regardless of the logged in user. However, if you make changes in the Lustre application that affect the default settings and then save these changes to a grade file, the default settings will be overridden the next time you load the project.

While logged in, the user can override some of the project default settings, such as Render Mode in the Local menu. However, these overrides only last for the duration of the session. Restarting the application resets the settings to the values set at project creation.
