Is there any flaw in the code shown at - https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_node
I am seeing only one blue cube present in the window !

/** Sample 2 - How to use nodes as handles to manipulate objects in the scene.
- You can rotate, translate, and scale objects by manipulating their parent nodes.
- The Root Node is special: Only what is attached to the Root Node appears in the scene. /
public class HelloNode extends SimpleApplication {
public static void main(String[] args){
HelloNode app = new HelloNode();
app.start();
}
@Override
public void simpleInitApp() {
/* create a blue box at coordinates (1,-1,1) /
Box box1 = new Box( new Vector3f(1,-1,1), 1,1,1);
Geometry blue = new Geometry(“Box”, box1);

mat1.setColor(“Color”, ColorRGBA.Blue);
blue.setMaterial(mat1);
/* create a red box straight above the blue one at (1,3,1) /
Box box2 = new Box( new Vector3f(1,3,1), 1,1,1);
Geometry red = new Geometry(“Box”, box2);
Material mat2 = new Material(assetManager,

mat2.setColor(“Color”, ColorRGBA.Red);
red.setMaterial(mat2);
/* Create a pivot node at (0,0,0) and attach it to the root node /
Node pivot = new Node(“pivot”);
rootNode.attachChild(pivot); // put this node in the scene
/* Attach the two boxes to the pivot node. /
pivot.attachChild(blue);
pivot.attachChild(red);
/* Rotate the pivot node: Note that both boxes have rotated! */
pivot.rotate(.4f,.4f,0f);
}
