= The Node Editor =

This section explains the window in general, and its header menu options. It also tells you how to enable nodes for use within Blender.

==Accessing The Node Editor==
There are two ways of reaching a node editor up on your screen:
{{clr}}

[[File:Manual-Part-VI-Using_Nodes-WindowsType.png|frame|left|Select the Node Editor window.]]
[[File:Node_Editor_Screen_Selector.png|frame|right|Choose "Compositing" from Screen Layout Menu .]]

{{clr}}
1) select "Node Editor" from the Editor Type selector menu.
{{clr}}
2) click the "Compositing" button ({{Shortcut|Ctrl|left}})from the Choose Screen Layout menu. This will bring up a composite four-panel window layout with Node Editor, UV image editor, 3D view, Properties and Timeline panels, each of which can be changed to suit the specialist purpose for which the Node Editor is to be used.

A typical Node Editor screen is shown here. The Node Editor panel has a graph-paper style background and a header (it may also have optional toolbar and property sidebars which are toggled by the T and N commands respectively). The header consists of a purpose selector (1) and several other components which vary according to the selected purpose.

By default, the header, when first displayed, is uninitialized as shown:
{{clr}}

==Activating Nodes==
*What nodes to use?
**If you want to work with a material node map, click the ball in the Material/Compositing node set selector. (see ''Node Editor Header with Material Nodes enabled.'')
**If you want to work with a compositing node map, click the face on the Material/Compositing node set selector. (see ''Node Editor Header with Compositing Nodes enabled.'')
*To actually activate nodes, click the {{Literal|Use Nodes}} button.
*The first time that you select either a Material or a Compsiting node map, the Node Editor window will be instantly filled with starter input and output compositing nodes already connected together.

==Node Editor Window Actions==
When the cursor is in the window, several standard Blender hotkeys and mouse actions are available, including:

;Popup menu
:{{Shortcut|Space}} - Brings up a main popup menu, allowing you to add, view, select, etc.

;Delete
:{{Shortcut|X}} or {{Shortcut|Del}} - Deletes the selected node(s).

;Box select
:{{Shortcut|B}} - Starts the bounding box selection process. Position your cursor and {{Shortcut|lmb}} click & drag to select a set of nodes.

;Cut connections (box)
:{{Shortcut|lmb}} click & drag - Starts a box selection, BUT when you let up the mouse button, all threads (connections) within the box are broken.

;Undo
:{{Shortcut|ctrl|Z}} Very helpful if you forgot to press {{Shortcut|B}} before box-selecting, eh?

;Redo
:{{Shortcut|ctrl|Y}} or {{Shortcut|ctrl|shift|Z}} - You can use this if you used "undo" a bit to often :)

;Select multiple
:{{Shortcut|shift|lmb}} or {{Shortcut|shift|rmb}} - Multiple node select.

;Grab/Move
:{{Shortcut|G}} - Moves your current selection around.

;Execute
:{{Shortcut|E}} - pumps inputs through the noodle, refreshing everything.

{{Note|1=Standard Window Control|2=Node maps can get pretty hairy (large and complicated, that is). The contents of the window, (the node map) can be panned just like any other Blender window by clicking {{Shortcut|mmb}} and dragging about. Wheeling {{Shortcut|wheel}} up/down or using the keypad<br>{{Shortcut|pad+}}/{{Shortcut|pad-}} will zoom in/out. The window can be resized and combined using the standard window techniques (see ''Navigating in 3d Space'').}}

==Node Editor Header==

=== At a glance ===

On the window header, you will see header options:
*{{Literal|View}} - to see things more clearly;
*{{Literal|Select}} - to do things more clearly;
*{{Literal|Add}} - to walk with...err..to add Nodes, organized by type;
*{{Literal|Node}} - to do things with selected nodes, akin to vertices;
*a Material or Compositing node set selector;
*a {{Literal|Use Nodes}} button;
*a {{Literal|Free Unused}} button.

=== Menus ===

==== View, Select and Add ====

These popup menus provide the basic functions:

;{{literal|View}}
:This menu changes your view of the window, standing in for the standard keyboard shortcuts {{Shortcut|pad+}} (zoom in), {{Shortcut|pad-}} (zoom out), {{Shortcut|HOME}} (zoom all) or equivalent mouse actions.

;{{literal|Select}}
:This menu allows you to select a node or groups of nodes, and does the same as typing the hotkey to select all {{Shortcut|A}} or start the border select {{Shortcut|B}} process.

;{{literal|Add}}
:This menu allows you to add nodes. Please see the next section for a discussion on the types of nodes that you can add, and what they do. Clicking this menu item is the same as pressing {{Shortcut|space}} when the cursor is in the window

==== Node ====

;{{Literal|Show Cyclic Dependencies}}
:{{Shortcut|C}} - Ok, so you've been adding and connecting nodes to your heart's content, and you haven't run out of memory yet. Selecting {{Literal|Show Cyclic Dependencies}} will show you where you have connected your threads in a circle. For example, you can easily connect a mix output as input to another node, and then connect that node's output back to the mix node input, resulting in a little circle where the image just runs round and round. Left alone, it will eventually get tired and dizzy and crash your computer.

;{{Literal|Hide}}
:{{Shortcut|H}} - Hides your selected nodes. Just like vertices in a mesh.

;{{Literal|Grouping}}
:Most importantly, this menu option allows you to create a user-defined group of nodes. This group can then be edited and added to the map. To create a group, select the nodes you want, and then {{Literal|Node}} → {{Literal|Make Group}}, or just use the keyboard shortcut {{Shortcut|ctrl|G}}. Edit the name using the little input box in the group. Groups are easily identified by their green header and cool names you have picked for them.

;{{Literal|Delete}}
:{{Shortcut|X}} - Deletes selected nodes.

;{{Literal|Duplicate}}
:{{Shortcut|shift|D}} - Makes an Unlinked copy, with the same settings as the original.

;{{Literal|Grab}}
:{{Shortcut|G}} - Moves the little nodes around according to your mouse, just like with meshes.

{{Note|1={{Literal|Duplicate}} - Faked you out|2=The new copy is placed '''exactly over the old one'''. But it isn't the connected one, so playing with the controls will do nothing to your images, even though it '''looks''' like it's connected with the little threads coming out of the node that is '''underneath'''. You have to move the duplicated node to reveal the connected node beneath it.}}

{{Note|1={{Literal|Grab}} - Reminder Only|2=Just like my mother-in-law, the menu item does not actually do anything; it's just there to remind you that you can press the {{Shortcut|G}} key when your cursor is in the window and actually accomplish something with your life (like rearranging nodes in the window).}}

=== Buttons ===

==== Material/Composite Selector ====

Nodes are grouped into two categories, based on what they operate on:
* to work with [[Doc:2.4/Manual/Materials/Nodes|Material Nodes]], click on the {{Literal|ball}},
* to work with [[Doc:2.4/Manual/Composite_Nodes|Compositing nodes]], click on the {{Literal|face}}.

==== Use Nodes Button ====

This button tells the render engine to use the node map in computing the material color or rendering the final image, or not. If not, the map is ignored and the basic render of the material tabs or scene is accomplished.

==== Free Unused Button ====

This button frees up memory space when you have a very complex node map. Recommended.

==== Backdrop ====

Use the active viewer node output as a backdrop. When enabled, additional settings appear in the Header and the Properties Panel:

; {{Literal|Backdrop Channels}}
:Set the image to be displayed with {{Literal|Color}}, {{Literal|Color and Alpha}}, or just {{Literal|Alpha}}.

; {{Literal|Zoom}}
:Sets how big the backdrop image is.

; {{Literal|Offset}}
: Change the screen space position of the backdrop, or click the {{Literal|Move}} button, or shortcut {{Shortcut|alt|mmb}} to manually move it.

==== Auto Render ====

Re-render and composite changed layer when edits to the 3d scene are made.
