AS#3 changing material Textures

Question

I cant seem to find a solution, anyways basically im trying to add a new dynamic texture to a 3D model using Away3d engine with flash

   var myImage:BitmapData = new BitmapData(256, 256, true,0xFFFFFFFF);

   // i cant seem to reference this to my 3D model in the example: Myevent(enter frame):

   myModel.material = new TextureMaterial(new BitmapTexture(myImage))

I have tried different things along the above method, i have checked the away3d docs and cant find something similar for my current situation:

Im using the latest Away3d lib, and flash player 11...all my models works and load with there original embedded materialtTextures, im just trying to change them to a bitmap or texture that i have dynamically created

Take a look here:

https://github.com/away3d/away3d-tutorials-fp11/blob/master/tutorials/materials/basic_shading/src/Basic_Shading.as

They use Away3D’s Cast utility class to create BitmapTexture objects and they also add a bunch of different texture maps - hopefully this helps

** EDIT --- This Tutorial Does Work **

Added

public bmt:BtiMapTexture;

....
private function initMaterials():void {
    this.bmt = new BitmapTexture(new BitmapData(256,256, true, 0x222277FF));
    sphereMaterial = new TextureMaterial(Cast.bitmapTexture(this.bmt));
    sphereMaterial.specularMap = Cast.bitmapTexture(this.bmt);
    sphereMaterial.lightPicker = lightPicker;
}

And I got a nice blue sphere

My solution is:

var mesh:Mesh = 'the mesh for changing'
for each (var item:SubMesh in mesh.subMeshes) {
item.material = null;
}
mesh.material = new ColorMaterial(0xFF00FF);
