Shadows in tilemaps

Hello, I am having real difficulties with lights and shadows in my game.

I have set up a directional light, put shader material on GameObjects which I want to light. The sprites react according to intensity of the light, as you can see in the picture - https://prnt.sc/m2axs9.


The problem is, that I don't know, how to set up shadows for these blocks. I want for the few blocks on top to be visable, and the rest of them to slowly slip in to darkness. Fairly similarly to Terraria. I just can't find any tutorial on the internet.

Any advice would help me a ton.

 

This is huge mystery to me as well, seems all other old forum guides are no longer working

 

I hope this is not too old of a thread to bump. Has anyone fixed this?

 

That looks like an excellent candidate for vertex colour.
