Weird terrain shadows

Questions & Answers
1

Hello, I am making a game and in the test scene I have a large terrain object covered in grass with mountains around the side, this has only just started happening. My problem is that the terrain’s shadows seem to be glitching, especially on the mountains. I am using realtime global illumination from a directional light. What is the problem here?

well not sure if itll work but for me the only fix was to change the directional light normal bias and bias to 0.25 and setting your camera view frustum near clipping to a higher value or your far clipping to a higher value or both that fixed it for me , its obviously a shadow z fighting issue .
