Sounds like you need to pull your camera farther back from the scene in Vue and render again.

I've made maps for the envirosphere with the free version of Vue before but I only do skies because of this very thing ;o). If anything else is added, it's always out of scale from the rest of your Poser scene. You need to keep in mind that the envirosphere is VERY large compared to anything else in your Poser scene.
