@Matt, I suppose the way I set up my code sidestepped the cloning of meshes within meshes. I have groups of OBJ files with no mesh children, and I simply clone those. In order to logically associate those OBJ meshes I implemented the AssetManifest to map them to "game objects," conceptually (so the barrel game object in the AssetManifest is made up of a barrel_rings OBJ, barrel_top OBJ, and barrel_body OBJ). Also, in Broomstick you can only have 1 material per OBJ file and my game objects have multiple materials each. I don't know if this is true of other model file types, but it figured largely in how I wrote these classes.
Anyway, my code is cumbersome as a result, but it does obviate the need to clone ObjectContainer3Ds or Meshes with Mesh children. I trust that a more robust clone process is in Broomstick's future, and hasn't been written yet as a matter of relative priority.
