How to set shadow caster behavior to affect individual tiles

I am working on a super secret project, (not really that cool, just a 2D point and click shooter) and I want the vision of the player to be limited. I created a light object over the player and made the tile set I'm using a shadow casting object. Just wondering if there is a way to have that behavior affect individual tiles. I'm assuming it's super easy but I spent easily 2 hours trying to figure it out and I've hit a dead end. Any help is much appreciated.

You can't do it with one tilemap. But you can put two tilemaps on top of each other - one normal and another one invisible. On the invisible tilemap set only those tiles which you want to cast shadow and add ShadowCaster behavior.
