Shader Code from Oliver2s and tranparency code from Matt_Aufderheide.

In Wed, add a big Hollowed cubes and increase it so that it involves your level and activate the flag Sky of Hollowed cube.
The water terrain needs to have a 3rd skin (a normalmap).
You also need to have a SkyCube+6.tga inside your level folder.
Apply terrainobject action to your terrain and Water action to your water terrain.
Make a WaterShader.wdl and include it inside of your level.wdl.
You can find the code for each files (WaterShader.wdl; water.fx; clip.fx) below.
