So picture you have a plane that is supposed to be water.
Below the plane is a mountain shape.
The water plane actually animated down on the Y axis allowing the mountain to come out of the water.
I tried adding a Collision to the Water. Then setting the mountain as the collider.
I've been messing with it a ton but it just ends up kindof sticking to the mountain and then never really settling back into place like water would.
Im sure there are a 1000 better ways of doing this, I just dont know any of them lol.
