your set probably has single sided objects
1 turn your document style to outline for the set
2 select a top or side camera
3 adjust selected camera to locate the main camera in your scene
now you can see where the main camera is proceed as your muse desires
I don’t know what “single sided objects” are, but this problem hasn’t existed in any version of DAZ Studio I’ve used (2.x - 4.5) and I don’t recall it in earlier versions of Poser that I used (versions 6 and 7). Is there no way to correctly display these models without going through the extra steps you outlined?
Attached are screenshots of the two models in DS 4.5 (Hyperion only comes with Poser shaders)
