As you manipulate the object, the value is updated
immediately and the new value is displayed in
the States list. If slaves in multiple states are
highlig hted, values are updated for t hose in the
first state only.
Set State—Updates the highlighted state
(master track) to its current v alue. To use this
option, highlight the m aster track in the Reactions
list and the state in the States list. Manipulate the
master object in t he viewports, a nd then click Set
State to update the state value. Available only when
a state is highlighted in the States list.
Delete State—Deletes any items hig h lig hted
in the States list.
Value—This column shows the current value or
values for the st ate: the master parameter(s) on
the State## line and the slave parameter(s) on each
slave line within a state. You can edit a single value
(not groups of three in parentheses) by dragging
vertically on the value in the t able.
Thefollowingthreeparameters,whichappearas
columns in the States list, apply to slaves and are
normally controlled via the graph curve. They’re
availableonlyiftheslavehasCurveturnedoffin
the Reactions list.
These parameters are based on the fact that
states can influence one another, so that you get a
blending between them.
Strength—This is a biasing factor that affects a
state’s relative influence when one or more s tates
overlap. A greater Strength value influences a
value towards a state and a smaller one influences
the value away from it.
Influence—Thedistancefromthemasterstate’s
value to the maximum extent of its r a nge of
influence.

Graph
Reaction Manager’s graph displays curves that
graph the master values on the horizontal axis and
slave values on the vertical axis. It shows data of all
states for items highlighted in the Reactions list.
If a m aster is highlighted, the graph shows states

highlighted, but the master isn’t, the graph shows
data for those slaves only. You can edit data using
the graph by dragging points.

other graphs in 3ds Max, such as the Material
Editor Output rollout (page 2–1621).Thetoolbar
above the graph offers functions for moving and
scaling points on the graph, as well as inserting
new ones (that is, new states). The same functions
are available by right-clicking the graph, and if

select a Bezier point, you can reshape the curve
by moving its handles. You can drag a region to
select multiple points, and then edit them together.

Right-click menu
Reaction Manager’s right-click menu provides
quick access to a n umber of commonly used
functions. It also contains the Replace Master
function, which is unavailable elsewhere in the
