I know Unity Terrain isn’t the most robust thing but has anyone ever seen this issue where a plane (in this case, the water) clips trees/details at certain angles?
I had the same issue with a particle effect that I was able to fix by creating a unique Sorting Layer, but Sorting Layers in 3D...?
Anyway, I have never seen this one before, so hopefully, one of you knows how to fix it.
This was posted a long time ago. However for any future visit, you can fix this by changing the render queue of the water to be geometry based instead of from shader.
