by the way what plugin are you using, and where did you get it?
i would need one too

I believe ASE exports animation keyframes. However, most people just write their own animation exporter plug-in. It isn’t that hard, and there are samples in the 3dsmax SDK that comes with the program.

Also you can use flexporter to make your own export (FLEXPORTER HOMEPAGE).
