On my site you can find a script which lets Daz Studio users export
scenes and render them in Blender, including the use of the Blender Cycles renderer
the Daz script exports the scene as an .obj file and creates a python script which is then
used by Blender to load the .obj (scene) and do all the tedious chores needed to make
the scene render correctly.
Since Carrara users also want to render scenes in Blender/Cycles i wrote a blender-python script
which uses the same services as the Daz Studio version : a kit of blender python scripts named mcjBlendBot )
Later in 2013 i’ll probably improve on this since the results are not as good as the Daz Studio version
