Is unmapped .duf scene content valid
If I save a scene subset as a .duf and categorize the automatically generated content thumbnail, it gets saved somewhere. However it's not a mapping of any folder listed in the Content Directory Manager under DAZ Studio Formats.
Do I care? Is there any reason I would still need to map it if it can be seen without being mapped? And then what exactly is the DAZ Studio Formats mapping accomplishing or is it not needed for .duf scenes?
Mapping it creates a duplicate content thumbnail, except that one has the word "Set" and the other doesn't.
