Node ‣ Move, Rotate, Resize


G, R, S

Move a single node by clicking and dragging it around. A node can be clicked almost anywhere to start dragging. Multiple nodes can be moved after pressing G.

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

A node can be resized by dragging the edges on the left or right side.

Connecting Sockets


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


Drag the link from an input socket and let it go keeping it unconnected.




Node ‣ Duplicate



Click LMB or RMB on the desired node, press Shift-D and move the mouse away to see the duplicate of the selected node appearing under the mouse pointer.


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.




Node ‣ Copy, Node ‣ Paste


Ctrl-C, Ctrl-V

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


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


Delete X, Delete

Deletes the selected node(s).

Delete with Reconnect Ctrl-X

Delete the node(s) without losing the connections.




Node ‣ Toggle Node Mute



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


Individual node links can be muted with Mute Links.


Hide H

Collapses the node so only the node header is visible. This can also be toggled by clicking the triangle at the top 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.



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.
