Pay $20 for Hexagon and use the Studio-Hex bridge. I haven't done it with genesis; I'll give it a run through in a few, but if DAZ hasn't borked it, that is the way to do body/head morphs. I did a lot with the mil2/3/4 figures.

Dynamic hair used to work quite well, but DAZ has slapped it a few times. I'll do run with it too; I had intended to for an M4 optitex dyamic render {dynamic loin cloth and stiff hair/beard? Not going to work }

Body painting, I have bad news. Does not work well with multiple shader domain objects, sorry. It has it's uses; 3D paint, but texture painting on figures isn't one of them.

And I have always had to fake caustics for water   I can make a water caustics texture with Genetica then use it as a gel in a light and bump map on the water surface. Yes it takes some doing to get it right, and yes barn doors on the spot light helped.

I'm sure it can be done in carrara, how is the question.
