Well I installed the DSON importer and it appears as it should under the Scripts menu in Poser.

Then I followed a video tutorial on how to create a Poser scene from within Daz Studio. The procedure did produce the Cr2, png and and Py files, of which I then copied into a new folder in my Poser Runtime/Character folder. Then I could find the scene I just converted in my Poser Figures library but when I brought the scene onto Poser stage nothing appeared. What is the next step?

Just to clarify, the scene I'm converting is just that, it's a scene with a house, a yard, a ground plane and plants & trees.
