Left: Spotlight with negative m ultiplier subtracts light from
the scene.
Right: Multiplier o f 0 and a negative density on a shadow
whose color is white creates the effect of a negative shadow.

A negative Multiplier value reverses the color of
the light, so a red lig ht would become cyan (the
complementary color). In addition, the map image
in a projector light becomes a negative image.
Multiplier Cur ve
Multiplier curves are special f u nction cur ves that
you use to apply animated value displacements to
other function cur ves.
When you edit keys and function curves, you
apply localized changes to y our animation at
specific times. By applying a multiplier curve to
theoriginaltrack,youaffecttheentirerangeofthe
original animation.
A multiplier curve shifts the value of the original
track up or down. At a g iven frame, the va lue of
a multiplier curve is a scale factor applied to the
value of the original funct ion curve.
The default value of a Multiplier curve is a
horizontal line with a value of 1.0.
Values greater than 1.0 increase the value of the
function curve.
Values below 1. 0 decrease the va lue of the
function curve.
Values less than 0.0 negatively scale the value
of the func tion curve.

In
Physique (page 2–927)
, by default, any number
of overlapping envelopes can influence vertices.
This is specified by the N Links option on the
Vertex-Link Assignment rollout (page 2–974)
of

sub-object level (page 2–1001)
.
Typically, N Links is t he preferred choice. For
special purposes, such as developing for a game
engine that has limited support of overlap, you ca n
limit the number of links (with their envelopes)
that can affect a vertex.
Networ k M a nager
The Network Manager service (Network Manager)
is a service that must be installed on at least one
computer in each group of computers that will
participate in network rendering.
The Network Manager communicates with a
specified group of Network Rendering Servers to
assign jobs and monitor rendering progress. The
Network Manager also handles the scheduling of
jobs and the configuration of servers through the
Queue M onitor client.
It’s often best to place the Network Manager on
a computer that isn’t in use as a workstation and
isntshutdownregularly. TheManagerService
can impact CPU and network performance
when network rendering is taking place, and the
Network Manager must be present at all times for
network rendering to work.
