parameter-wiring setup, so that you could
potentially set up a chain of controlled parameters.
For two-way wiring , the s of tware assigns Wire
controllers of the appropriate k inds to each of
the parameters and they are cross-linked so that
changing either parameter cause linked changes
in the other.
Note: You should establish all object hierarchies
before wir ing parameters in a scene. If you
change the hierarchy of an object that has a wired
parameter, it w i ll ta ke on new parameters, which
could introduce undesired results in your wired
parameters.
Tip: Use Schematic View (page 3–640) to see all the
w ired parameter relationships in a scene. You can
also use Schematic view to wire parameters.
Procedure
To atta ch wire par ameters:
1.
Select the first object you want to use.
2. Choose Animation menu > Wire Parameters >
Wire Parameters, or right-click the object and
choose Wire Parameters.

can link.
Note: Wire Parameters works only with
parameters that can be animated. The menu
options displayed depend upon the selected
object and are the same options you would see
for the selected object in Track View.
3. Choose the parameter you want to link to
another object from the displayed menu.

4. Move the cursor to the second object you
want to use. When the cursor changes from
an arrow to a selection cross, you are over a
valid destination object. Click to select the
destination object.
A pop-up menu displays the parameters to
which you can link.
5. Choose the parameter you want to link f rom
the displayed menu.
The Parameter Wiring dialog (page 2–412)
opens, with the two parameters you selected
highlighted in yellow.
6. If you like, change the parameter highlighting
in the dialog, and then click the d irection
buttons between the two panels to determine
the control direction: one way either way, or
both directions (changes to either object’s
selected parameters affect the other objec t).
7. Click Connect to complete the wiring.

The Parameter Wiring dialog a llows you to
define the relationships for Wire Parameters (page
2–411). In this dialog, you can create new one
and two-way cont rol relationships between object
parameters, edit existing relationships, and create
or edit expressions which define the parameter
relationships.
Only parameters that can be animated can be
wired. Sub-objects, such as vertices, must be
animated before they can be w ired.
Parameter wires can be used to establish
connections from Manipulators (page 2–27)
