Motion Capture Utility 655
B ank Amount—
Adjusts the amount of the banking
to one side or the other, depending on whether the
val ue is positive or negative.
Smoothness—Controls how rapidly the roll angle
changesasanobjectmovesthroughbendsinthe
trajectory. Smaller values make an object more
responsive to subtle changes in the cu rve w hile
larger values minimize jerkiness.
Allow Upside Down—Avoids the situation where
an object flips when going around a vertically
oriented path.
Samples group
Specifies the range of frames over which rotation
keys are generated, and the number of keys to be
generated.
Start—Specifies the first frame rotat ion keys are
generated.
End—Specifies the last frame rotation keys are
generated.
Samples—Specifies the number of rotation keys to
be generated in the specified range.

Motion Capture Utility
Utilities panel > Utilitie s rollout > M otion Capture button
The Motion Capture utility drives your animation
using per ipheral devices, such as MIDI keyboards,
joysticks, and the mouse. While driving the
animation, you c an record it in real time.
The motion capture system in 3ds Max is handled
in the following way:
1. In Track View, assign motion capture animation
controllers to the specific tracks you want
controlled by external devices.
2. After assigning the Motion Capture cont roller,
open the Properties dia log for the tr ack and
bind the typ e of peripheral device(s). As
an example, the Rotation Motion Capture
controller has three rotat ional axes to which
youcanbindonedeviceeach.
3. After binding devices, adjust their settings
and p arameters in the lower portion of the
TrackPropertiesdialog. Thesecontrolsvary
depending on the type of device.
4. On the Util it ies panel, open the Motion Capture
utility. You can test and record your motion
for any combination of tracks over any range
of frames.
The following motion-capture devices are
included with 3ds Max:
Mouse Input Device rollout (page 2–661)
Keyboard Input Dev ice rollout (page 2–661)
Joystick Input D evice rollout (page 2–662)
MIDI Device rollout (page 2–663)
Procedures
To assign a Motion Capture controller to tracks:
The first step in using motion capture is to assig n
motion-capture controllers to the tracks you want.
1. In the Track View hierarchy, highlight the
Transform track you want.
2. Choose Controller > Assign.
The Assign Controller dialog is displayed.
3. Choo se Motion C apture (might start w ith
“Position,” “ Float,” “Scale,” or other), and then
click OK.
