Hey thank you for the detailed answer.
I followed Ben Cloward water shade episodes, and the shader is good applied to a plane but for a big world with camera turned around 360 , the fresnel and the depth fade are all gone wrong. I believe it’s also because he said in the tutorial it won’t work well if the plane is bit deformed in height so you know I just gave up,Going to leave this as it.
I’m not very advanced in material and quite honeslty water is super hard to get right with cesium tiles. This is why they have an option to get the material if it detects the tile has water on it but they also said it doesn’t detect all place in earth “water” .
So just tried for 4 hours or so with Ben’s material to adapt and it’s not great from certain angles so I will just let this one like with the harsh transition.
