but ..there is some particularity

a light group looks like

light_group {
  light_source source and color
  sphere {position,radius /*no_shadows*/ }
  //global_lights off

}

if you add
global_lights on  in the light group then the light comming from others
sources will or will not illuminate your sphere, means that shadows will be
or not cast ..
