Remote nodes have no input or output. They are only used to control (remotely) the parameters of other nodes. They can be used to either gather important parameters of a complex graph or define the parameters of a subgraph node.
Creating a remote node¶
Remote nodes can be created by dragging a Miscellaneous/Remote node from the library panel to a graph panel.
Configuring a remote node¶
Remote nodes provide three kinds of controls:
linked widgets, that are associated to parameters in the graph and whose values are copied into the target parameters
configuration widgets, that can be used to define named configurations of the target parameters
named parameters, that can be used in expressions in all nodes of the subgraph
Configuration widgets are used to create named configurations for associated parameters in the graph.
To create a configuration widget, click on the button and select a parameter to be controlled in another node. Then, link all other parameters that should be controlled using the button.
When all parameters are linked, you can create your first configuration. Set the values of all parameters for this first configuration, then select the add configuration option in the configuration’s drop down button. you will be propted for a name for the new configuration.
Repeat the same operation (set all parameters values, then add configuration) to add all other configurations.
Selecting a configuration using the drop down button will recall the associated parameters values.
It is also possible to rename, update or delete a configuration using the drop down button.
Named parameters can be declared in Remote nodes, and used in parameter expressions of all nodes in the same subgraph.
To create a named parameter, just click the “ab” button, and enter a unique name in the leftmost text entry. The parameter can then be referenced by name with a dollar prefix in parameter expressions of all nodes in the subgraph.
It is possible to configure the lower and upper bound as well as the increment step by clicking the pencil button of the parameter.
