Im a bit confused with the number of ways to texture a mesh..

So, applying texture on loaded mesh in Away4x for rookie:

var texture:TextureMaterial;

I should best use:

texture = new TextureMaterial(new BitmapTexture(image));

texture = new TextureMaterial(new BitmapTexture(image).bitmapData);

texture = new TextureMaterial(Cast.bitmapTexture(image));

texture = TextureMaterial(e.asset) as TextureMaterial;
?

ATF is a must, I know, but just wanted to deal with this question first.
Im using Flash cs6 with FD.
Thanks very much
