|Hotkey:||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 translated 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.
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 turns orange.
- Make Links F
- Select multiple nodes with open sockets, then use the Make Links to create links between them. Use Make Links again if there are other nodes which can be connected.
- Make and Replace Links Shift-F
- Make and Replace Links works similarly to Make Links, but it will replace existing links if any exist.
Drag the link from an input socket and let it go keeping it unconnected.
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, grab a node and move it slightly to see if something is hidden underneath.
- Delete X, Delete
- Deletes the selected node(s).
- Delete with Reconnect Ctrl-X
- Delete the node(s) without loosing the connections.
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.
- 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 Toggle Node Options operations.
The tools 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. This can also be used to recover some information from a failed render. For this to work, Save Buffers must be enabled.
- Read Full Sample Layers Shift-R
- Reads all the render layers using full sample only used in Blender Internal.
