What if the vendor doesn't have poser but does have DS?  That would be the simplest explanation for not making it usable in poser.  To bad there isn't any DS to poser export tools that can save things like morphs...

So are you saying that the Vendor used the DS Primitives and built these scenes "Enitirely" in DS?

If not and those buildings were constructed in some other 3D App, then Why not offer the Object Files?
