   This example creates a link:http://en.wikipedia.org/wiki/Phong_reflection_model[Phong]-illuminated blue material. Use it for illuminated, naturalistic objects, such as characters, buildings, terrains, vehicles. Needs a light source, otherwise it will be invisible.
  
positive.code: mat.setTexture("ColorMap", assetManager.loadTexture("Textures/monkey.png")); // with Unshaded.j3md

  To give a Phong-illuminated material a texture:
  
  *  Specify at least the DiffuseMap texture: 
  
negative.code: mat.setTexture("GlowMap", assetManager.loadTexture("Textures/alien_glow.png"));
  ----
  
  To deactivate glow:
  
  *  Set the `Glow` color to `ColorRGBA.Black`.
