For some reason the terrain shader flickers shadows all across it at a slight distance. I don't know what causes this. Its extremely annoying, I don't know how to fix it. Thanks!
I also have had this issue as well. I can change the flicker by adjusting the near clipping plane on the camera to 0.3 but then it clip thru objects unless it about 0.1. If I reduce it more<0.1 the flicker gets worse and worse. I don't understand how such a small near clip plane adjustment can effect the shadows so immensely. Cascade adjustments don't fix it they just mask the problem. I wonder if have Graphics Job(Experimental) checked has any effect. I was playing with that. Because the problem went away for 6 months but returned the next upgrade. I am Using 5.5.1, 5.5.0 did not have the issue for me.
