Parameter referencing is a powerful feature that allows you to drive the value of one parameter using the value from another. This creates a live link between nodes, enabling complex and procedural behaviors. For example, you can make the width of a Rectangle node always equal to the radiusX of a Circle node.
When a parameter is being controlled by a reference, its input field in the Parameters Panel will be disabled and highlighted with a dashed purple outline.
Shortcuts
| Copy a parameter to create a reference. | Alt+C |
| Paste a parameter reference. | Alt+V |
| Remove a parameter reference. | Ctrl+Shift+LMB |
Creating a Reference
Creating a reference is a simple copy-and-paste operation:
- In the Parameters Panel, hover over the parameter you want to use as the source.
- Right-click to open the context menu and select Copy Parameter.
- Navigate to a different node and hover over the target parameter you want to control.
- Right-click and select Paste Relative Reference.
The target parameter’s value will now be linked to the source parameter. Any changes to the source will be immediately reflected in the target.
Removing a Reference
You can remove a reference in two ways:
- Context Menu: Right-click > Remove Parameter Reference.
- Shortcut: Hover over the referenced parameter and use the shortcut Ctrl Shift LMB
Once removed, the parameter will revert to its last known value and can be edited manually again.
Visualizing References
To help you keep track of connections, dashed purple lines are drawn in the Node Graph between nodes that have parameter references. You can toggle the visibility of these lines from the main menu under View > Show Reference Lines.
