Unity water shader and UVs

How are UVs supposed to be mapped to use with the Unity water shader?
I searched but found nothing and I tried different combinations but with no good result.
So I had to use the water pool from Unity but I’d like to use my own mesh for it… is it possible?

Yeah, just swap some other mesh in the Prefab’s Mesh Filter.

The UVs are pretty straightforward.

Uh?

I tried with a plane of 10x10 squares with UV mapped planar 10x10 and it didn’t work…
