   Illuminated materials require a <<jme3/advanced/light_and_shadow#,light source>> added to at least one of their parent nodes! (e.g. rootNode.) Illuminated materials are darker on the sides facing away from light sources. They use Phong illumination model (default), or the Ward isotropic gaussian specular shader (WardIso) which looks more like plastic. They do not cast <<jme3/advanced/light_and_shadow#,drop shadows>> unless you use a FilterPostProcessor.
