How do i convert an outfit to body slide that is not in the outfit/body selection

[Subboyty]

As asked in the title, I am having a hard time finding a good tutorial that lets me place in some of the adult outfits into the body slide so I can get them to really fit my preset and really in general any new outfit I might get outside of that.  It seems the program only recognizes vanilla outfits and I have to go and place in new outfits myself.

It all depends on if the author included bodyslide files or not.  Most do though.  If they did not, you'd need to create a new outfit studio project - which there are ample tutorials and information around on doing.  Good place to start on that is the BodySlide & Outfit Studio wiki page.
