Tip:
Use the reactor m anipulators in a wireframe
viewport. (See Viewport Right-Click Menu
(page 3–731).) Also, for the Position Reaction
controller , you might ha v e to change viewports
to see a particular manipulator clearly.
The specific m anipulators and their use are
described below.
Manipulators for R eactor Controllers
Reaction controllers for position and rota tion
tracks have g raphic manipulators to help you
adjust their settings.
Other Reaction controllers, such as point3, scale,
and float, do not have manipulators.
Manipulators are visible and usable while
the Select and Manipulate button (page 2–15) is
turnedon. Thisbuttonisonthedefaultmain
toolbar (page 3–686). When you move the mouse
over a manipulator , the manipulator turns red to
show that dragging or clicking it will have an effect.
Tip: Use the Reaction controller manipulators in
a w ireframe v iewport. (See Viewport Right-Click
Menu (page 3–731).) Also, for the Position
Reaction controller, you might have to change
viewports to see a p articular manipulator clearly.

manipulato rs to control (or simply display)
different reaction values.
Reaction cycle manipulator : Click this to cycle
among the various reactions in the Reactions list.
The display of the manipulators and indicators
changes to show their settings for the ac tive
reaction.
This manipulator is a small yellow circle that
appears in the lower-left corner of the active
viewport, near the icon for coordinate axes.
Influence m anipul ator: Draginaviewportto
change the manipulator’s size, which changes the
reaction’s range of influence.
This manipulator is a yellow sphere that turns red
when you c an dr ag it. At the center of the Influence
manipulator is the Reaction Value manipulator.
Reaction Value manipulator: Drag in a viewport
to change the reaction value, which for a position
track is an XYZ location.
This manipulator is a light blue sphere t hat appears
at the center of the Influence manipulator.
Obje ct P ivot in di cator: Shows the pivot point
location of the master object.
This indicator is a dark blue sphere. You can’t
manipulate it.
Reaction State manipulator: Drag to adjust the
reaction state. For position reactions, the reaction
state is an XYZ location that the slave object
approaches, depending on the animation of the
master object and t he Influence value.
This manipulator is a small green square.
Reac tion State in dicator: Shows the reaction state
value. This indicator is independent of the square
green Reaction State manipulator, which you can
drag in v iewports. As you drag the green square,
the indicator follows it.
This indicator is a sm all dark-blue dot.
Rotation Reactors
The Rotation Reaction controller has a single
manipulator, which controls the reaction’s
Influence parameter.
Influence m anipul ator: Draginaviewportto
change the manipulator angle, which changes the
reaction’s range of influence.
