It is similar but bigger and more complex. It's not hard to use, though. I imported a scene containing the Cyclorama into Vue 4 and it came in fine. However, you'd have to do some tweaking with the material settings to make it look right. Something I didn't have the time or inclination to do. Freyfaxi, to answer your original question, it works very well, is simple to use, and renders nicely in Poser 4. Haven't tried it in 5 yet. You can make your own textures for it to create different backgrounds, although you have to figure out how for yourself. There are no instructions on how to do it.
