How is a real shadow?

Here we have a real tree shadow:

Them definitions aren´t constant at the distance; the part which is far from the tree, is more diffuse and less dark.

On the other hand, we have the game shadows:

As you can see, in these ones we have a perfect definition in all projection of the shadow.

I don´t know if this is possible, but I believe it would be intereseting to get more diffuse shadows, like the real ones.

 

Interesting.

 

Yeah, that would be cool. Maybe not yet... do we want to make the shadows even more demanding?

 

Don't the Shadow Blur options do something? or is that just for the cars.
