 == Creating Terrain
 
 To create terrain, first select the `Scene` directory under your `Project Assets` folder, right click and select `menu:New[Other>Scene>Empty jme3 Scene]`. This will generate an empty scene in that directory. Right click this new file and then select `Edit Terrain`. This will open the new file in the `TerrainEditor` and display your scenes file structure in the `SceneExplorer` located at the bottom left window of the SDK. In the `SceneExplorer` window, select a node (usually your root node) in your scene. +

 This will pop up the `Create Terrain` wizard that will walk you through the steps for creating terrain. Make sure you decide now how large you want your terrain to be and how detailed you want the textures to be as you cannot change it later on!
 
 In order to see the terrain, you will need to add light to your scene. To do this, right-click the root node in the `SceneExplorer` window and select `menu:Add[Light>Directional Light]`. Alternatively, you can create your terrain and press the btn:[Toggle cam light] button located in the menu at the top of the open terrain window. You will need to add a light to your scene by code in the `simpleinitApp()` method later so you can see the terrain.

 === Changing the texture scale
 
 The field in the table to the right of the diffuse and normal textures for your texture layer is the scale. Changing that value changes the scale of the texture. +

 You will notice that the scale changes when you switch between Tri-Planar and normal texture mapping. Tri-planar mapping does not use the texture coordinates of the geometry, but real world coordinates. And because of this, in order for the texture to look the same when you switch between the two texture mapping methods, the terrain editor will automatically convert the scales for you.
 Essentially if your scale in normal texture coordinates is 16, then for tri-planar gets converted like this: 1/terrainSize/16

 There are a few things your code needs to do to load the terrain.
 
-*  You must first use the asset manager to load the scene, see the <<jme3/beginner/hello_asset#,hello asset tutorial>>.
-*  The terrain (as you can see on the left in the editor) is a sub-node of the scene, so you have to write code to investigate the child nodes of the scene until you find the node that is the terrain, see <<jme3/the_scene_graph#,this tutorial for scene graph concepts>>.
