I've been playing around a bit with bagginbill's dome and using like 8000 pixel photographs as the image map for backgrounds. This is nice, but is there a way to control the exact location where my characters will appear in the photograph? The only thing i can do is increase or decrease the focal length of my main camera, but that generally only moves them a little bit forward or backward in the same spot. Which means i can only use one location in that photograph.

Is this a limitation of using that method, or is there a way i can control where the characters will appear in the image?
