[away3d] MovieMaterial how to play movieclip once

[cism]

Hi

I have movieclip mc1 whcih animates form at frame 1 to 10 and frame 10
i have stop();.
and i use this movieclip for moviematerial

var materialA:MovieMaterial = new MovieMaterial(mc1,
{interactive:false, smooth:true});

I want to play the mc1 just once but it keeps playing,
I added loop = false; but still keep playing.

How do i make the mc1 play once not loop?

Thanks!
