Two further resources…and again, I know Papervision isn’t really part of the Metaverse but combined with other work from Macromedia, it will eventually converge (plus, I just think it’s really cool).

First tutorial is in Portugese and provides a nice intro with a follow-up more advanced discussion.

A tutorial “from the ground up” includes screen shots and does a great job of describing the integration to 3DS etc.
