Problem with shadow quality

[Andrea]

I have a big problem about shadow quality.
In the marked point shadow is not good. (In real world is more darken)
Now there is active 1 light with setting reported.
In other project i had this problem too.
What is a right buffer dimension?

Andrea,

Try decreasing the "Transition" field. I usually set transition to somewhere between .5 and 1. However, that usually means you have to increase the sample rate to 10 or 20.

Hope this helps,

Thanks bensyverson
I try 1 and 10; shadows are fantastic!
This setting became my default, too.
Time render is only few seconds plus
