Hi

In my experience DAZ products are all geared to importing DAZ shop content. There is not much in the way of import/export and it can be problematic the exchange files between Carrara, Daz Studio, Bryce and Hexagon even though they are all sold by DAZ3D.

Iray renders are nice but the DAZ interface is a bit torturous.
