export simple animation from 3ds max 2011

I found this tutorial http://www.bleepng.com/blog/2009/05/...tion-tutorial/

It worked fine with maya but there is some issue when I tried to export it from max 2011. The animation does not play. There is no animation in Unity. Some help as to how to export from max and import into unity. There are no bones just simple animation.

Thanks

Does the animated object simply disappear when you go into play mode?
