I seem to remember a while back, that there was an aftermarket script which converted legacy hair styles & also added morphs to them. I think it might have been an OOT product, but it may not have been.
Long shot here, but was it maybe a sickleyield product? I know the hat/hood helper has a bunch of morphs, and they’ve done several conversion tools. I’m not familiar with the one you’re thinking of but my gut is telling me it’s them.
That might point me in the right direction. Thank you.
I seem to remember the sales pitch was that not only could legacy hair styles be used on current generation, but also it added some potentially useful styling & pose morphs to them.
