As soon as you have made a tiny change (new metadat etc.) to the project file you get this message to re-render.
It would be great if it were possible to turn off this warning.
THANKS!
Right click a project tab for those options under subproject rendering.
Yeah, thanks, it's there. But who was supposed to find it there when the popup appears in the media explorer. I wonder why there are not all preferences in the Preferences.
