Quick Node Palette
The Quick Node Palette is a floating window which lets you browse and create nodes.
The Quick Node Palette can be opened by pressing the “Tab” or “N” keys on your keyboard, while the Node Network layout is active. You can choose which category of nodes you want to see from the Quick Node Palette submenu.
The Quick Node Palette window
There are two sections to the Quick Node Palette. The top section lets you choose a browsing mode, either a popup menu (left image above) or hierarchical list/treeview (right image above). The bottom section displays the nodes in the category selected in the browsing section.
The browsing section lets you choose which category of nodes to display. For example to see all the heightfield operation nodes select the "Heightfield operator" category. Some categories also have subcategories. An example of this is the Shader category. Choosing the Shader category will display all of the nodes in that category as well as all the nodes in the Shader subcategories. If you only wanted to see, for example, the atmosphere shaders then you can choose the Shader > Atmosphere subcategory and only the atmosphere shaders will be displayed.
You can choose to browse node categories using a popup menu or a hierarchical list. To change between browsing modes simply drag the splitter bar between the top and bottom sections of the palette.
Terragen will search as you type the name of a node in the input field and display any nodes that match the pattern. You can refine the search by using the “Search Options” button and choosing one of the selections from the submenu. Clear the input field by clicking on the “X” button to the right of the search box.
The quickest way to create nodes using the Quick Node Palette is to start typing the name of a node as soon as you’ve pressed the “Tab” or “N” keys. Terragen will immediately find the nearest matching node in the list. To add the highlighted node to your project press the “Enter” key. You can also double click on a node name to add it to the project. This will create the node at the location occupied by the Quick Node Palette in the network view you were last working in, and close the Quick Node Palette window.
The Quick Node Palette lets you choose favourite nodes for quick access. Favourites are shown in the Favourites category.
To create a favourite select the node in the palette and then click the "Add Favourites" button at the bottom left of the palette.
To delete a node from the Favourite category list just select it and press the delete key. You can only delete a node from the Favourite category.
To bring up the Quick Node Palette displaying your Favourite categories, press the “Shift+N” keys on your keyboard.
Clicking on the “Online Help” button at the bottom right will bring up the Terragen documentation for the selected node in your web browser. If no node is selected, nothing will happen.

A heightmap or heightfield is an array of height values, usually in a grid which describe the height at specific points in a defined area. Heightfields are used to represent real-world and virtual terrain in a specific, easily converted format. Most heightfields can be represented as simple image data in grayscale, with black being minimum height and white being maximum height.
