Click on the
Input
tab of the SoftFX
properties. Change the Motion Force
setting to
500
% and recalculate.
Return Motion Force to
100%
and
click on the
Operator
tab. The Opera-
tor tab fine-tunes the effect of motion
(or optionally wind) on the object.
There are two Operator maps. At this
point, the top one is set to <all>,
meaning that the motion will affect the
entire object.
7. The wave graphic to the left is a visual
indicator of the falloff that will be
applied to your object's motion. Change
the EffectSize to
0%
and recalculate.
The residual motion has been severely
reduced and it now looks as if SoftFX
has not been applied. The EffectSize
setting works hand in hand with the
Motion Force setting to determine the
extent of the object's reaction to
motion. Change EffectSize back to
100%
and change WaveCycle to
1
.
Calculate and check the results. The
number of times the object moves after
it reaches its final keyframe has been
reduced. Change WaveSize(s) from 0.5
to
3
and calculate again to see the
results. The time it takes to complete
the motion after the object reaches its
final keyframe has been extended.
8. This motion isn't very realistic so let's
change the settings to something more
“natural.” Keep EffectSize at
100%
and change WaveCycle to
5
. This will
create more motion after the last
keyframe has been reached. Change
WaveSize(s) to
0.1
. This will shorten
the time needed to complete the resid-
ual motion. Press
Calculate
and check
the results.
The object now appears to have come to a
hard stop. As you can see, the Operator set-
tings greatly affect your object's response
to motion. Up to this point, we've only
affected our object's position in response to
Figure 19-38: Change Motion Force to 500%.
6.
You can see that the object is now
much more responsive to its motion.
Figure 19-39: The Operator tab allows you to
fine-tune the effects of motion on your object.
