yeah, GenX killed it for me too! and a few other plugins
weirdly the morphs are there but not accessible in the Carrara vertex room!
for clothes too!
I DID find a messy Carrara workaround I used on my Predator Huntress in the “Alien v Preadator the kiss” video
export the fitted head as an obj with morphs enabled in the obj export dialogue, export an unfitted head with the alternate unuseable morph you want
reimport the fitted one and in Carrara at least, you can select it and the hip and attach skeleton then in the vertex room load the other head as a morph target.
ironically if the morphs had NOT been there in the vertex room, I might have been able to do this with an autofitted head.
I cannot get morph loader in studio to work EVER! or maybe this would work on autofitted stuff there!
