How to fix this. I tried with WaterHeightMap Settings, but when I switch to landscape, the same irregularity appears.
Update:
The resolution is 8129, when I set up the landscape I calculated the measure (I imported the map from gaea) 100000*100/8129 and I got a good measure, but I experimented and multiplied the result by 4. So the resolution is too small for such a large landscape. I don’t know if that could be the reason.
