again, i think you're not looking at how NGM Petite actually works.  testing it (got done with my V3 render and taking a pause from another), i see it only installs 9 new morphs.  the rest are NGM morphs and Morphs++ morphs.  iirc, Posermatic said the GND V4 one would be stand alone, but NGM Petite presets use the 11 NGM morphs and  at least 20 Morphs++ morphs.  at least by my count.  and while taking out the unique morphs produces definite, significant and noticeable changes, they're basically refinements.  most of the shape is produced by the other two sets of morphs, so you can't use it alone and even approximate the presets.

i'm not sure how one would account for them in clothes exactly.  because presets aren't the same as morphs.  i mean, you could match the presets, but that's a  very limited usage.
