Tip:
Use the reactor manipulators in a w ireframe
viewport. (See
Viewport Right-Click Menu
(page 3–774)
.) Also, for the Position Reaction
controller, you might have to change viewports
to see a particular manipulator clearly.
The specific manipulators and their use are
described below.
Manipulators for Reactor Controllers
Reaction controllers for position and rotation
tracks have graphic 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 2–26) is
turnedon. Thisbuttonisonthedefault
main
toolbar (page 3–733)
. 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
wireframe viewport. (See
Viewport Right-Click
Menu (page 3–774)
.) Also, for the Position
Reaction controller, you might have to change
viewports to see a particular manipulator clearly.
Position Reaction controller
ThePositionReactioncontrollerhasasetof
manipulators to con trol (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 sett ings for the active
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 can drag it. At the center of the Influence
manipulator is the Reaction Va lue m anipulator.
Reaction Value manipulator: Drag in a v iewport
to change the reaction value, which for a position
track is an XYZ location.
This manipulator is a light blue sphere that appears
at the center of the Influence manipulator.
Obje ct Pivot indi cator: Shows the pivot point
location of the master object.
This indicator is a dark blue sphere. You can’t
manipulate it.
Reaction State m anipulator: 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 the Influence value.
This manipulator is a small green square.
Reaction Sta te indicator: Shows the reaction state
value. This indicator is independent of the square
green Reaction State manipulator, which you can
drag in v iewpor ts. 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 p arameter.
Influence m anipul ator : Draginaviewportto
change the manipulator angle, which changes the
reaction’s range of influence.
