var mesh:Mesh;
if (event.asset.assetType == AssetType.MESH)
{
  if(this.somethingName==“something”)
  {
    mesh=Mesh(event.asset);
    var bm:BitmapMaterial=new BitmapMaterial(new SomePic().bitmapData);

    mesh.material=bm;
  }
}

He said:

Problem solved, I had to use

context.setVertexBufferAt(X, null);

where X is the number of the vertex stream I want to unset.

i don’t understand….. :(

That seems to be a bug in the way vertex buffer clearing is handled. Can you submit a bug at https://github.com/away3d/away3d-core-fp11/issues with any details you can provide?

ok!

I am also getting this error in the Away3D 4.  What is the status of this bug?

Thanks,
