The Environment backgrounds work with the cyclo-rama from daz3d.com-which would work; remember that they accept shadows, too, like any prop.

I don't use the cyclorama for the most part due to how flat everything looks; even with the 'trees and plants' that come with it.  (Which are made up of flat planes with jpg/png images like my last post suggested.  XD)

The scenes that Alex offered up should be included in your D|S application if you are using that program.
