title: Three js Light through transparent plane .. Shadow
body: <p>Is ist possible to have three js send light through a transparent object? </p>
  
  <p>I have a plane with a cloud. The Light (sun) is above the cloud and below the cloud plane a shadow is hitting another (terrain) plane. But sadly the shape is the one of the Mesh (rectangle) not the one of the cloud. I understand why the shadow is rectangular but is there any way to create the wanted effect?</p>
