Invisible Shallows / Walkable Water

Well this is a pretty decent editor trick and does not involve any triggers such as creating bridges
on water.

To begin with, you should know what terrains we are going to use:
Water Shallow
Water Medium
Shallows
(Note: Water Deep can also be used if desired)

Let us go step by step so that you understand how this is done. Have some patience as you read this guide even if skipping through the pictures may seem easier…

Step1

Open the Age of Kings or (The Conquerors expansion) editor.
Place some water shallow on the map. For a good effect, use a large area for the water surface.
So you will now have something like this:

Step2

Now place the shallow across one of the lengths on the water surface. But also note that the brush size should be tiny. So you will have a small bridge of shallow like this:

Step3

Now add the medium water to the edge of the shallows so you will see that the shallow becomes a bit invisible. But in reality it has been blurred of by mixing of terrain water shallow and water medium which are at the opposite sides of the shallow.
So you will have the following result:

Later you can add more water medium, water shallow or even water deep so as to make it camouflage in the river, lake or sea in which you are going to use it.
Here something like this :

Many more things can be done with this terrain trick. Such as:
1) Making a waterfall using different combinations of water (mostly using only water shallow and water medium).
2) Making a secret path out towards something like a big treasure.
3) Making mythological scenes. E.g.: gods that fight on water.
4) Making it appear that a ship has crashed into a rock and people are stranded in the ocean. Then the could either drown or be left on a rock.

The trick has only one drawback.It is that if the unit is tasked to the secret place (for example), the the unit will automatically know that there is a secret path and will use it to get there.
