How can I have a light not light up an object, but still cast a shadow on it?

I have a directional light that only lights up the player, but I still want the shadow to be cast on the scenery below. Yet if I use the culling mask to only light the player, I also don't get the shadow anywhere but the player.

Actually, I also wouldn't mind not having the light cast the self shadowing on the player either...

 

For anyone asking the same question as me in the future, here's the answer:
