Bryce, Papervision and panorama

I don’t know if you have used bryce but… Oh well I have a scene there and I have rendered a 360 degree panoramic projection. Now I wonder how to port that in flash with papervision. I know how to do the cube panorama with papervision. However the image I got from bryce uses some other kind of projection - not cubic one. Any idea how to either render images for cubic projection or use the 360 degree panoramic projection with papervision?
