10. Now choose the very first link you created. In this case chain_link, and go to menu - Reactor > open property editor. Make ONLY this links mass 0, and check off Unyielding. (This makes the object stay where it is, and allows it to be animated)
11. We are just about done. Now give all of your links a material (optional of course) BUT IT LOOKS BETTER!
12. Now go to the Utilities sub menu (menu to the far right).
13. Expand the Preview & Animation pull down menu. Now chose either create animation, or preview in window. Since this is our first go I think we should preview in window ïŠ Like so.
Now just click on Simulation > play/pause.
Go back and make any setting changes that you wish. Make it more realistic, or more cartoonish. It's up to you. When you're ready to go just choose Create animation in the reactor pull down instead of preview in window. This will automatically add the keys.
YAY! A working animated chain that only took 10 mins to make.
