I’m sorry but I’m afraid of 4.5, not been reading good things about errors, crashes, duff files parenting objs and broken plugins
I can get clothes to convert and retain morphs, checking the “Reverse Source Shape From Target” Genesis as “Source” Target is what you want to convert and clothes will retain their morphs, however Hair will not do it and I don’t know why?
edit, sorry i was typing as you posted
the hair I just tried and didn’t get to work was, Dione Hair from Renderosity.
all that shows up for morphs in the parameters tab is a bunch of things labeled neck, like around 30 or so things labeled neck
and none of them do anything from just testing several random sliders
