   There are two sliders that affect how these tools operate:
   
   *  Radius: how big the brush is

  There are a few things your code needs to do to load the terrain.
  
  *  You must first use the asset manager to load the scene, see the <<jme3/beginner/hello_asset#,hello asset tutorial>>.
  *  The terrain (as you can see on the left in the editor) is a sub-node of the scene, so you have to write code to investigate the child nodes of the scene until you find the node that is the terrain, see <<jme3/the_scene_graph#,this tutorial for scene graph concepts>>.
  *  You also have to set the camera on the LOD control in order for it to work correctly:
