Genesis is certainly better in many ways - more versatile, easier morphs, better deforming. I don’t use it yet because to be of any real use it needs all those add-ons, which I won’t buy until it works properly in Carrara.
The importing of dynamic clothing I’ve been trying is all Gen4, stuff, on gen 4 figures - which I used to be able to do perfectly in DS3 using Daz Collada.
Eventually found a method of getting Animate animations into Carrara 8.5 - export as .pz2 from DS, into Poser, export as bvvh - Carrara can read that perfectly.
Heck, even a static pose with conforming clothing saved in duf comes into Carrara in a mess - but I can do that right here, so no problem for me.
Still no dynamic clothing with duf - Pierre is on it’s case.
