I am looking for all objects in a hierarchy that have meshes. This includes the object itself and any of its children. The purpose is to attach a mesh effect.

If I use:

var mesh : MeshFilter = gameObject.GetComponentInChildren(MeshFilter);
mesh.gameObject.AddComponent ("MeshExplode");

It finds the first mesh and works fine. But as I want to have all meshes I am trying the following:

var meshes : MeshFilter[] = gameObject.GetComponentsInChildren(MeshFilter) as MeshFilter[];

if(meshes)
{
  for (var mesh : MeshFilter in meshes) 
  {
     Debug.Log("Found mesh =======================================");
     mesh.gameObject.AddComponent ("MeshExplode");
  }
}
else
{
  Debug.Log("No meshes");
}

This doesnt find any meshes and I am completely confused to why.
