Radio Node System by Jens Kafitz











Overview


The Radio Node System is a combination of custom nodes for the Nodegraph and Menu actions interacting

with these Nodes.


The purpose of the System is to provide the option to hide connection lines between nodes in order to have

a cleaner Nodegraph with less intersecting lines.


Hiding and unhiding a connection to a radio node using Right Mouse Click / Misc / Toggle Radio Nodes.


In addition to directly connecting a Radio Node to another Node you can also expose nodes anywhere in the graph via a

Radio Transmitter Node.


Radio Transmitter Nodes allow you to connect a selected Radio Node via the Right Mouse Click / Misc/ Connect to Transmitter Option

to a Transmitter anywhere in the Graph.


Connecting a selected Radio Node to a previously created Radio Transmitter Node via the Right Mouse Click / Misc / Connect to Transmitter Dialog



An additional function of the Radio Node System is to automatically reconnect imported Node Networks to specified Transmitter Nodes.


Example of Automatic Connection on Impport


If you import a Node Network into your Nodegraph - either via Session Scripts or the Right Mouse Click / Edit / Import Nodes Function -

any radio node of that imported network that does not have a connection will try to reconnect to a Transmitter Node with the same Name that was connected

to the Radio Node before it was exported.


This functionality works across projects allowing you for example to expose commonly used information such as Occlusion, Curvature, Material ID maps etc.

via Transmitters and creating and exporting Node Network Templates that can automatically detect these Outputs in any Project you import the templates into.

Radio Node




   




The Radio Node is a custom node with its only purpose being to act as a 'dot' or 'connection' that can hide its input line.



You can connect its Output to another Node just like any other Nodegraph Node..



..and feed another node into its Input. The Radio Node does no processing.

It's only purpose is to pass through incoming information





Known Issues & Workaround: Nodes with multiple Outputs

.

Due to a limitation in current Mari API Versions, Nodes with more than one Output Port cause issues when any other Output than the first is directly connected to the Radio Node that is being toggled.


As a workaround insert a second radio node or dot node inbetween




Radio Transmitter Node




   




The Radio Transmitter Node is a custom node that can be called by a Radio Node from anywhere inside your current Nodegraph via the Connect To Transmitter Menu Option.



It can can be left either without an output connection or can be utlizied as part of a network chain



Radio Transmitter Nodes contain a checkbox (on by default) to determine if they are accepted nodes for the Automatic Reconnection of Radio Nodes on Import



Toggle Radio Nodes





   




Toggle Radio Nodes allows you to hide and show connections on a Radio Node.


If your Node selection in the currently open Graph Tab includes Radio Nodes the selected Radio Nodes will be switched to their opposite state -

visible connections will become invisible, invisible connections will become visible


If your Node selection in the currently open Graph Tab includes Radio Transmitter Nodes, the Radio Nodes connected to the Transmitter will be switched to their opposite state -

visible connections will become invisible, invisible connections will become visible


If your Selection is empty or does not include Radio Nodes or Radio Transmitter Nodes, all Radio Nodes in the currently open Graph Tab will be switched to invisible on the

first command execution, then to visible on the second.


When Radio Node Lines are hidden, the Radio Name will be appended with the Name of the Node connected to the hidden connection.





Naming


Both Radio Nodes and Automatic Reconnect on Node Import will ignore any characters that are encompassed in square brackets [  ] .


Example:

A Radio Node connected to a Radio Transmitter named


MyRadioTransmitter [Radio Transmitter]


will be called


Radio Node [MyRadioTransmitter]


after the connection has been made invisible.




Connect to Transmitter





   




With one or multiple Radio Nodes selected, executing the Connect To Transmitter Menu Option will display a list of all available Radio Transmitter Nodes

in your current Nodegraph. By selecting one of the Radio Transmitter Nodes, the selected Radio Node(s) will automatically connect to the chosen Transmitter.





Automatic Connection to Transmitters on Node Import


Using a combination of Radio Nodes and Transmitters allows for a high degree of automated workflows through the use of Automatic

Connection Building when importing Node Networks through the Right Mouse Click / Edit / Import Nodes or File / Session / Options in Mari.



If your imported Node Network contain one or multiple Radio Nodes that



your current Nodegraph will be searched for a Radio Transmitter Node matching the Name in the Radio Node's Square [ ] Brackets


If ...



... the imported Radio Nodes will be automatically connected to the Transmitter after import.






Naming


Both Radio Nodes and Automatic Reconnect on Node Import will ignore any characters that are encompassed in square brackets [  ] .


Example:

A Radio Node connected to a Radio Transmitter named


MyRadioTransmitter [Radio Transmitter]


will be called


Radio Node [MyRadioTransmitter]


after the connection has been made invisible.




This workflow is recommended for templated nodegraphs, gizmos etc. that always need to access per-project information such as Occlusion, Curvature etc.


This automatic connection behavior can be deactivated via a Preference under Mari / Edit / Preferences / Nodegraph Section





Additional Radio Node Actions






Additional Actions


The actions below are not embedded into the Mari interface but can be found under the Scripts

Menu and are available for Hotkey assigments in the Hotkey Edior




Jump to Radio Connection




   



Jump to Radio Node Connection will jump the Nodegraph view to a connection associated with a Radio Node.


Executing the command a second time will jump back to the original Node


Executing the command a second time will jump back to the original Radio Node.





Toggle Selected Radio Nodes




   



Toggle Selected Radio Nodes is nearly identical to Toggle Radio Nodes however it only works on selected radio and radio transmitter nodes

and will not hide/unhide all connections in the currently open graph tab, when no radio nodes are selected



Expand all Radio Nodes




   



Expand all Radio Nodes will set all Radio Node connections in the currently open Graph Tab to visible



Collapse all Radio Nodes




   



Collapse all Radio Nodes will set all Radio Node connections in the currently open Graph Tab to invisible



Radio Node Preferences




   



A small number of preferences exist to better configure Radio Node behavior to your needs.



When On, a Radio Node Connection will be automatically toggled hidden when a connection is made to a Transmitter via the Connect to Transmitter Tool


Turns off the functionality to automatically reconnect imported Radio Nodes without a Connection to a Transmitter matching

the [ NODENAME ] (in Square Brackets) on the imported Radio Node.
