Chapter 14. 3D Layers > Auto-Orienting 3D Layers

Auto-Orienting 3D Layers

Using the Auto-Orientation command, you can make a 3D layer automatically rotate along its motion path or toward the top camera layer (see “Using Cameras” later in this chapter)—which saves you the trouble of keyframing the Orientation property manually. Alternatively, you can leave Auto-Orientation off and adjust the layer's rotation independently of other factors.

To specify an Auto-Orientation setting:

1.
Select a 3D layer.

2.
Choose Layer > Transform > Auto-Orient, or press Command-Option-O (Mac) or Ctrl-Alt-O (Windows) (Figure 14.23).

Figure 14.23. Choose Layer > Transform > Auto-Orient.


The Auto-Orientation dialog box appears (Figure 14.24).

Figure 14.24. The Auto-Orientation dialog box appears.


3.
In the Auto-Orientation dialog box, select one of the following options:

Off— Select this option to turn off Auto-Orient and adjust rotation independently.

Orient Along Path— Select this option to make the layer rotate so that its local Z axis points in the direction of the layer's motion path (Figure 14.25).

Figure 14.25. Orient Along Path makes the layer rotate so that its local Z axis points in the direction of the layer's motion.


Orient Towards Camera— Select this option to make the layer rotate so that its local Z axis points in the direction of the top camera layer (Figure 14.26).

Figure 14.26. Orient Towards Camera makes the layer rotate so that its local Z axis points in the direction of the active camera.


For more information, see “Using Cameras” later in this chapter.

4.
Click OK to close the dialog box.
