In Daz Studio there is a 3D ridge selection under Edit > Customize. I hit this and then went into CS3 and found it under File > Automate. Hit that and it opened a dialog box with questions. Once I answered those it loaded the entire scene into CS3. I'm still mucking about with it but will let you know what I find out. I'm mainly interested in the fact that it goes back to Photoshop Ver. 7 as well as the updated versions.
