The Position XYZ controller splits the X, Y, and Z
components into three separate tracks (simi larly
to the Euler XYZ Rotation cont roller (page 2–318)).
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 3–792) that
let you create explicit axis keys using Set Key Mode
(page 2–280).
Procedure
Ex ample: To use the Position X YZ and Noi se
controller together:
1.
Create a sphere.
2. In the Motion panel > Parameters > Assign
Controller rollout, select the Position 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 Assign Controller rollout, expand the
position track and select Z Position.
6. Click Assign Con troller, and then select
Noise Float.
7. Play the animation. The sphere moves around
the keys that were created earlier. The r andom
up and down mo vement in the Z axis is
generated by the noise controller on the Z track.
This effect can also b e 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 Bezier Float Controller is assigned to each track
by default. Use Key Info (Basic) and Key Info
(Advanced) to control how the keys behave. See
Bezier Cont roller (page 2–310).
