User Manual

Publish a parameter in order to link
other parameters to it.
Once a parameter is published, you can right-click another parameter and choose Connect To >
[published parameter name] from the contextual menu. The two values are linked, and changing
the parameter value of one in the Modifiers tab changes the other.
Using the pick whip between two parameters provides similar linking behavior with more
flexibility.Pick whipping between parameters is covered later in this chapter.
Connecting Multiple Parameters to One Modifier
A single modifier or published parameter can be applied to multiple parameters so they all act
as one. This is handled through the Connect To submenu. As with modifier assignment, the list
is filtered to show only options that are suitable for the parameter you’ve right-clicked on. When
you do this, the connection is bidirectional; editing either parameter will cause the other
parameter to change.
The Connect To menu connects modifiers
to multiple parameters.
Adding and Inserting Multiple Modifiers
Modifiers can be connected to each other and branched, just like nodes in the Node Editor. For
example, the Calculation modifier outputs a number, but has two Number parameters, both of
which can have modifiers added to them. If you want to insert a modifier between the existing
modifier and the modified parameter, use the Insert submenu of the parameter’s
contextual menu.
Available Modifiers in Fusion:
 Bézier Spline: Adds a Bézier spline to the Spline Editor for animating the selected
parameter.
 B-Spline Spline: Adds a B-Spline spline to the Spline Editor for animating the selected
parameter.
 Calculation: Creates an indirect link that includes a mathematical expression between
two parameters.
