I've done this extensively, but getting the lighting and(especially) shadows to work is a major pain the butt. Also, it is EXTREMELY hard to make an interactive environment using this technique. Also, this technique pretty much only allows STATIC camera shots. If you move your Poser camera (like for a dolly shot, or a simple zoom) it immediately becomes obvious the background is JUST THAT ... a background. Now, it is POSSIBLE to synchronize both the camera in Poser and the one in your Bryce scene, but talk about difficult! So what it comes down to is, yes, you can do blue-screen/alpha type shots, but you are going to be very limited in the kind of shots you can accomplish. -Tim
