Well, I've added runtimes to Poser before, different versions. I imported runtimes to the Poser 11.2 Renderosity version. I'll try to post 2 screenshots, one showing the contents of the runtime with the Construct elements seachnasaigh made. I was able to add that as a runtime to Poser 11.2. But, the second screenshot shows that when I try to open that in Poser 11.2, it shows up as "empty."
