Disk 1 is being re-released with a whole new title and cover (the original was knocked up quickly for the siggraph deadline by some 'artist' who thought changing the title would make it fit better !!!!!!!!!!!!!) just note that the content is EXACTLY the same as version 1... its not an upgrade or a version 2.
We also have Autodesk official stamp of approval on this version!
Disk 2 in the series will be released shortly - with the correct title and everything!
