This is the result:
It works, so that it becomes more dark blue, as the water gets deeper.
When you are on deep water, it looks just as realistic.
Pros:
-Is realistic
-Is render-efficient
-Is easy to make
Cons:
-Does not work underwater
-Requires the sea bed to be textured in a specific way (more on that in the tutorial)
-Is not animated (can be done though)
