I've acquired the source from http://www.nexusmods.com/skyrim/mods/10578/? mod. It uses a number of predefined NPC configurations that are included externally.
Would it be possible to instead use vanilla-game NPC configurations (say Mavis Black-Briar) dynamically? I realize that I could export all the figures that I wanted and use them that way, but it would be simpler if I was able to just use the original asset.
