User Manual

Customizing Node Parameters
with User Controls
The user interface for each node in Fusion is designed to provide access to the parameters in a
logical manner. Sometimes, though, you may want to add, hide, or change the controls. This is
commonly done for simple expressions and macros, but it can be done for usability and
aesthetic reasons for favorites and presets.
User custom controls can be added or edited via the Edit Control dialog. Right-click the name of
a node in the Inspector (in the header bar) and choose Edit Control from the contextual menu. A
new window will appear, titled Edit Control.
The Edit Control window.
In the Input attributes, you can select an existing control or create a new one, name it, define
the type, and assign it to a tab. In the Type attributes, you define the input controls, the defaults
and ranges, and whether it has an onscreen preview control. The Input Ctrl attributes box
contains settings specific to the selected node control, and the View Ctrl attributes box
contains settings for the preview control, if any.
All changes made using UserControls are stored in the node instance itself, so they can be
copy/pasted, saved to a setting, added to the Bins, or added to your favorites.
An Example of Customizing Directional Blur
In the following example, let’s suppose we wanted to create a more intuitive way of controlling a
linear blur than using the Length and Angle sliders independently.
