Hi guys.
I'm posting concerning shadow implementation. I have try to implement soft shadows with PCF. I have test with 2 "map" size and i haven't got the result that i was expecting.

Here its a map of 5X6 cube

Here its a map of 10X12 cube

Someone told me that i should use VSM so i did try it.
Here it's the 5x6 map with VSM

As you can see, it's a bit weird sometimes. How can i make it more pretty?

Even if actually my VSM map look weird, i want to continue with this technique and implemented bigger map. I will use cascading shadow map. Someone have a good tutorial or project or papers about that subject that could help me?

Thank you.
