Hey I was wondering if anyone had any resources on learning about object tagging. I found this site:

http://venice3d.net/awtimes.html

And this article from that page:

http://venice3d.net/2016create45.html

But the link at the bottom of the page where you can learn more about object tagging says I don't have the right credentials to view the page by Starheart.

I'm interested in learning because of something similar to the tags on this:

http://venice3d.net/2015create35.html

I'm trying to learn about tag 300, referring to modeling an object and putting a tag 300 on one of the polygons so if when you turn the object into a mover, you can click the polygon to start the mover.

Thank you
