HI wsxc 
Carrara 8 will import and use all your Daz3D “Poser type” content from your runtime.
Genesis currently only works in Carrara 8.5 (Beta) which is still being developed.
You can import a Daz Scene, depending on what’s in it.
for example:,
Some things like Uber-environment are specific to Daz Studio, so those type of things won’t work in any other program.
In the Carrara 8.5 (Beta), you can import the new “DUF” files, as well as loading Genesis and clothing from the new “Smart content” tab in the carrara browser.
Using Daz Studio 4.5, you can save “presets” for Characters, Materials , poses and animations, etc.. In the new DUF format which can then be applied to your figures in Carrara.
If you want to use Carrara, you’ll learn more about how Carrara works if you start by creating the scene in Carrara, rather than importing a complete scene from another program, ..but it is possible to import a Daz Studio Scene in DUF format into the 8.5 beta.
Hope it helps
