No top secret project, I was thinking it might be nice to have something other than the default male shape when you bring Genesis into Blender, like the Basic Female shape. However, I've since realized that if I was going to redistribute my morphs later, this wouldn't work out unless I could zero out the influence of the non-default morphs I didn't make myself. Still, for going back and modifying one's own work, being able to import a morph file could be handy.

I use DS4 Standard (4.0.2.55), and I have options for saving Character File, Shaping File, and Pose File DSFs. Pro or the CCT has more options, like Figure File, and I'm going to guess that Figure File should have everything like the base Genesis DSF. I'm still new to DSFs, so I can't really say what the difference between some of these are.

Here is how to export your own DSF: Load Genesis and apply any morphs you would like. Then, with just Genesis selected, go to File>Save As> and you should then see some DSF options. Unfotunately, I don't think the 'Smart' Content tab can find these, or I haven't figured out where it puts them because they weren't in Unassigned last I checked, while a DSF pose I made was.
