The Constant Z is used when creating motion keyframes. The Z function will use stop-motion keyframes and will not be interpolated, this can be very useful for cut-out animation. The Constant Z feature only works with 3Dpaths.
You can also enable the Constant Z option directly in the Function Editor or Function view for specific functions.
To enable the Constant Z option:
|1.||In the Timeline view, expand the function of the layer you want to set to Constant Z. Note that the 3D Path option must be enabled for that particular layer.|
|2.||Double-click on the Position function to open the Function Editor.|
|3.||In the Function Editor window, select the Constant Z option.|
