As3 Flash: property of 3d mesh - actionscript-3

Question

Below i have purposely made a test script: you can see it live at www.parele.com/plane.html
All source code is below, what im trying to do is change my mesh...please note:i want to change material of my model mesh , to another color , any color not create a new plane as this sample is an example to test this out not my actual hobby project, any files or info needed im happy to supply..I have been at this for a full over 20 hours stuck here and its killing me

Answer 1

I believe this is what you are looking for: SubMeshes
A mesh you pull from a model is usually made of at least on SubMesh, but can contain several. Changing the Material on that "root" Mesh object doesn't propagate to its SubMeshes. You need to iterate through its SubMeshes and change their material.
