Select a position track in the Track View hierarchy.
Track View menu bar
The Position XYZ controller splits the X, Y, and Z components into three separate tracks (similarly to the Euler XYZ Rotation controller). 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, there are now actions available from the
Customize User Interface dialog that let you create explicit axis keys using Set Key Mode.
Motion panel > Parameters > Position XYZ Parameters rollout
Displays controller properties for X axis transformation.
Displays controller properties for Y axis transformation.
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.
