The Position XYZ controller splits the X, Y, and Z
comp onents into three separate tracks (similarly to
the
Euler XYZ Rotat ion controller (page 2–312) ).
This provides separate control of the three tracks
when referenced from Expression controllers.
The Position XYZ controller assigns three keys
(one for each axis), by default.
In earlier versions of 3ds Max, you had to edit the
keys manually in order to create explicit axis keys.
However,therearenowactionsavailablefromthe
Customize User Interface dialog (page 3–836) that
let you create explicit axis keys
using Set Key Mode
(page 2–275)
.
Procedure
Ex ample: To use the Positi on XY Z and Noise
controller together:
1.
Create a sphere.
2. In the Motion panel > Parameters > Assign
Controller rollout, select the P osition track of
the sphere.
3. Click Assign Controller and choose
Position XYZ.
4. Turn on Auto Key and create three keys that
movethesphereontheXYplane.
5. In the Assig n Controller rollout, expand the
position track and select Z Position.
6. Click Assign Controller, and then select
Noise Float.
7. Play the animation. The sphere moves around
the keys that were created earlier. The random
up and down movement in the Z axis is
generated by the noise controller on the Z track.
This effect can a lso be created using the List
Cont roller to combine cont rollers.
Interfa ce
Motion panel > Parameters > Position XYZ
Parameters rollout
X—Displays controller properties for X axis
transformation.
Y—Displays controller properties for Y axis
transformation.
Z—Displays controller properties for Z axis
transformation.
When you select an axis, a Key Info (Basic) and
Key Info (Advanced) rollout is available to change
values.
A Bez ier Float Controller is a ssigned to e ach track
by default. Use Key Info (Basic) and Key Info
(Advanced) to control how the keys behave. See
Bezier Controller (page 2–305) .
