I managed to get V4.1's morphs to show up in WW2 but still none of the shoes i have tried to convert to V4 work hopefully someone will figure out why?
to put it in a simple way its as if the foot zone of the shoe is named wrong so that it doesnt conform to V4, the rest of the shoe conforms (if a bit of kilter)

Thankyou all who posted and to PhilC who induced these headaches on himself,lol.... keep up the good work

Getting old and still making "art" without soiling myself, now that's success.
