Position XYZ Controller

The Position XYZ controller splits the X, Y, and Z components into three separate tracks, similar to the Euler XYZ Rotation controller. This provides separate control of the three tracks when referenced from Expression controllers.

• Assign Controller > Position XYZ

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, there are now actions available from the Customize User Interface dialog that let you create explicit axis keys using Set Key Mode.

Procedures

Example: To use the Position XYZ and Noise controller together:

1. Create a sphere.
2. On the Motion panel Parameters Assign Controller rollout, click the Position track of the sphere.
3. Click (Assign Controller) and choose Position XYZ.
4. Turn on (Auto Key) and create three keys that move the sphere on the XY plane.
5. On the Assign Controller rollout, expand the Position track and click 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 vertical movement is generated by the Noise controller on the Z track.

   You can create the same effect with the List Controller to combine controllers.

Interface

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 Controller.
