Any solution for the artifacts (the black stripes) using dynamic light with cascade shadows?

Yes, I was testing with PCF shadows, but agravates the problem, the stripes are surrounded with noise… I was testing using low values to try more difuse shadows… but the result was horrible.

The best option is to place the meshes oriented to the sun. There are a day/night cycle, but the sun only rotates in one axis, so a cube properly oriented will avoid the problem at the morning hours and at the afternoon. And perhaps the bias a bit higher. I use 0.02, to 0.05 still looks enough good.

I have read in forums, and seems that others engines like Unity and Cry have the same problem with dynamic lights. In UE4 I think it’s possible to avoid using raytraced shadows (or area shadows, not sure).
