Menu

Node ‣ Move, Rotate, Resize

Shortcut

G, R, S

You can move the selected node(s) by simply clicking and dragging any empty part on them. Alternatively, you can press G, move the mouse, and click LMB to confirm.

In general it is recommended to arrange your nodes within the view such that the data flows from left to right, top to bottom.

The width of a node can be changed by dragging its left or right border.

Rotating (R) and scaling (S) only apply when you have multiple nodes selected and only affect the nodes’ positions.

Connecting Sockets

Interactively

LMB-click on a socket and drag. You will see a line coming out of it: this is called a link. Keep dragging and connect the link to an input socket of another node, then release the LMB. While multiple links can route out of an output socket, only a single link can be attached to an input socket.

To reposition the outgoing links of a node, rather than adding a new one, hold Ctrl while dragging from an output socket. This works for single as well as for multiple outgoing links.

Nodes that have no connections can be inserted on a link. Just move the node over the link and release when the link is highlighted.

Disconnecting Sockets

Interactively

Drag the link away from its input socket and let it go, keeping it unconnected.

Duplicate

Reference

Menu

Node ‣ Duplicate

Shortcut

Shift-D

Select one or more nodes, activate the menu item or press the key combination, then move the mouse to a new location and click LMB (or press Return) to place the duplicated node(s).

Obs

When you duplicate a node, the new node will be positioned exactly on top of the node that was duplicated. If you leave it there (and it is quite easy to do so), you can not easily tell that there are two nodes there! When in doubt, select a node and move it slightly to see if something is hidden underneath.

Copy/Paste

Reference

Menu

Node ‣ Copy, Node ‣ Paste

Shortcut

Ctrl-C, Ctrl-V

Not only the selected nodes but also the connections between them are copied to the clipboard.

Obs

The pasted node will be placed in the same position as when it was copied. Use the same cautions as when duplicating.

Delete

Delete X, Delete

Deletes the selected node(s).

Delete with Reconnect Ctrl-X

Deletes the selected node(s), then creates new links connecting their former input nodes to their former output nodes.

Mute

Reference

Menu

Node ‣ Toggle Node Mute

Shortcut

M

Muting a node removes its contribution to the node tree, and makes all links pass through it without change. Links will appear red as an indicator of passing through the muted node.

Tips

Individual node links can be muted with Mute Links.

Show/Hide

Hide H

Collapses the node so only the node header is visible. This can also be toggled by clicking the triangle on the left of the node header.

Toggle Node Preview Shift-H

Shows/Hides a preview region on the node that displays the frame after that node’s operation has been applied. This can also be toggled by clicking the material ball icon in the node header.

Toggle Hidden Node Sockets Ctrl-H

Collapses/Expands any input or output sockets that have no other nodes connected to them.

Toggle Node Options

Shows/Hides all node properties.

Collapse and Hide Unused Sockets

Applies both the Toggle Hidden Node Sockets and Hide operations.

Layers

Obs

These operators are only used in the Compositor.

Read Render Layers Ctrl-R

Reads all the current scene’s render layers from cache, as needed. This can be used to save RAM while rendering because the render layers do not have to be saved in RAM. And also for recovering some information from a failed render. For this to work, Cache Result must be enabled.
