[away3d] Apply moviematerial on 3ds mesh

[Erokare]

Hi there, I was just wondering if we can apply a moviematerial on a
Mas3DS mesh ?

i tried this :
var materialMovie:MovieClip = new causticsMovie() as MovieClip;
var causticsMaterial:MovieMaterial = new MovieMaterial
( materialMovie );

Mesh(model.getChildByName("NGon01")).material = causticsMaterial;



but i got a 1009 error.... is there a way to do it and how ?

thanks
