Start with pressing on Areas (8). On the right side of the level editor you can press on a dropdown box. Press it and look for “Liquid” when
you find it you press it.
When you have Liquid selected you need to make an area where you want the water to be, don't make it too high or you will player will drown.
Then press left mouse to create it. Now you have the waterish in the water. Now you need to make a plane that will set the texture
for the water. (Tip: It just goes on top so when you look down in-game you will see Water, if you do not set a plane, there will be water but it will be invisible.)
Press on Planes(9) > Search for a material > Textures > Water > Choose the water for your liking.
I preffer sewer_water since it gives you the creeps.
Make the plane as big as the Area is.
Drag the water ontop of the liquid area
Click on the water and go to Primitive tab and uncheck the “Collides” box.
