I am at wits end. I spent two days trying to figure out how to get each figure in a scene to cast its own shadow on to either the ground or area around it. I went thru step by step using the D|S pdf guide.  Changed lighting, each thing that was mentioned in the guide that had to do with shadows. 

But no luck. I could not even get a single shadow from a lone figure.

Need help as the shadows are need to make the scene look realistic
