Is Unity water bugged?Please help if u have ever got it to work?

Hi
So for 2 days now I have been trying to get the unity water to work with custom meshes for my rivers and nothing i tried worked.
Only thing that works is using the prefab or the unity waterplane as a base.
So i thought maybe i could import the base into blender reshape it a bit and …no it fails.
So i tried to just swap out the mesh in the prefab with my own…NO
So i thought maybe its the uv’s somehow so i imported it into blender again and screwedup the uv’s and it still worked .
I am tugging out my hair trying to figure this out so is it just impossible to use custom meshes with water in unity or is there a step i am missing.

Here are my steps
1 import mesh
2 choose water layer
3 apply the unityprowater material
4 apply water script
Thats all i know to do but it does not work.

I’m not sure if you’ll be able to get Unity water working for a river. Unity water is a very basic solution.

You might look into this (AQUAS flowmap rivers). This is the only river solution I’m aware of that is currently being worked on.

Oh ok thx i thought maybe it was just me screwing something up or my unity was persecuting me. Least now i know to try something else . Thx for the reply

So i was just trying a couple more ideas before i moved on and things were working so i started moving towards how i had done it a couple days back and it continued to work. Then i put my mountain mesh in the scene and the water broke.So somehow a mesh is breaking the water???This is one of the frustrating things about unity seemingly unrelated things somehow effect each other in bizare ways.
