Minecraft Rig Doesn't Have Shadow.

So, I have this Minecraft’s player rig, but the shadow doesn’t show. It just shows the shadow of a thing that I don’t know what is it but not of the entire figure. I’ve put a light spot in it, but there’s no shadow in the render, how can I fix it?

Too little info supplied.
