You can repeat this cycle, continuing to

like. The result is a “daisy chain” of parameter
w ires, so that as you modify the or iginal master
parameter, each slave parameter maintains a
constant relationship with the next in a line of
parameters.

Tree Views
Thedialogpresentstwotreeviewsthatdisplaythe
animatable parameters of all of t he visible objects
in the scene. The names of the currently selected
objects appear at the top. The tree views display
the objects in the s cene and allow you to select and
wire all of the animatable parameters of the objects
in the scene and the scene itself.
Thetreeviewsarecolor-codedtoshowexisting
wiring. A parameter with a wire controller
assigned to it (either as the member of a two-way
pair or as the slave in a one-way wire) displays
in red. When a wire-controlled parameter is
selected, all of the par ameters wired directly to it
are displayed in green text in the other Tree View.
In either case, if the parameter is inside a track t hat
is not expanded, the enclosing track will display
in red or green, so you can expand the tracks to
find the wires.
Note: If you open the Parameter Wir ing dialog
by wiring two p arameters, the tree views initially
display only the selected objects, highlighting
the parameters that you chose f rom the pop-up
menusduringthewiringprocedure.Ifyouwant
to expand the trees, to include all other animatable
parameters in the scene, click Show All Tracks.
The buttons above the tree views are:
Show All Track s—Brings you to the top of the
scene object list.
Find Next Parameter—Finds the next wired
parameter in the scene, expanding the t ree if
necessar y to show and select it. You can browse

repeatedly.
Note: If you click a wired parameter, its connections
are shown in green on the other tree view. While
the wired parameter is hig hlighted, the Show Next
Wire button on the other tree c ycles through the
green connections only, so you can quickly find
the selected wire’s connections.

Co ntrol Di rection—The Parameter Wiring dia log
provides three direction-control buttons b etween

control, either one-way or two-way:
•
Two-way connection [two-headed
arrow]—
Click this to link both parameters to
each other, so that changing either parameter
affects the other.
•
One-way connection: right parameter
controls left parameter [left arr ow]—
The right
parameter controls the left parameter.
