If what you're saying is that you imported a render from Vue to use as a background in Poser, fine, but you appear to be claiming to have exported a Vue scene (including that tree) to Poser. That's not possible. If you've figured out how to do it, by all means, let us know how it's done. It will be major news to a lot of people. Perhaps I've misunderstood something you wrote? Why would you want to export from Vue to Poser, rather than the other way around?
