I own the latest version of Vue Infinite, and love it.

But if you are just looking for a background for your figures, you may be happier with the Terradome. 

While Vue is somewhat Poser compatible, there's something of a learning curve.  As others have said, the materials need to be adjusted.  Yes, Vue can read Poser materials, but the results are not ideal, especially for things like human skin. (Though there are products like Skinvue to help out.) 

Vue's treatment of Poser's dynamic hair is also less than ideal. 

Honestly, even though I have and use Vue, I still use things like the Terradome sometimes, because it's quicker and easier, and often "good enough" when the focus is on the figures.
