It works well on 3 computers that I have tried, both pc and mac. I had thought about the second "unwrap" when a spherical image has to be mapped to a cubic world. That's another reason why I thought it better to look for a program that would convert a bunch of prerendered images into a cubic vr panorama, be it quicktime or panocube. But this is just guessing and I may be all wrong. Besides, I haven't been able to make anything worth watching with panocube, it keeps complaining that my image is not equirectangular (I hardly understand what that is. Must have someting to do with equal rectangels, or maybe equal sides?) Regards, Frank Bueters
