You'd have to export a sphere in several different ways and see how the hex changes between each different permutation. I don't know if this would work though as I really don't know much about hex files and how they are structured (although I hope to be learning soon at school). There was a guy who released a program called "bryce2Vue" for mac osx that would supposedly convert bryce scene files into vue scene files, but I and others could never get it to work... here's the home page for that application: Bryce2Vue Homepage you'll need access to a mac to try it out... Bryce itself would be very hard to crack because there is no source code and therefore it's in "machine language" which you won't make heads or tails of unless you are that kid from the movie mercury rising who can instantly decipher all those really complex codes. I'd second a motion for an open-source release, at least with some aspects of the program. I think it would really help Daz out to have more developers working on certain aspects of the program like exporting to various formats, materials, animation, etc. Then they could be universal binaries that could be compiled for any system...
