Apple Shake 4 Tutorials - Manual (Page 123)

Chapter 3 Depth Compositing 123
The first 10 frames look okay. At about frame 40, however, we begin to see just how
two-dimensional and superficial Betty really is.
Fortunately, Shake has a useful control that will take care of Betty’s 3D shortcomings:
faceCamera. This parameter automatically rotates an element in the 3D space to face
the camera, at every frame.
To force a 2D plane to face the camera:
1 In the MultiPlane parameters, click the Image tab and open the subtree for the L3
walking_woman layer.
2 Choose camera1 from the faceCamera pop-up list.
3 Click the Flipbook button again to generate a new preview of the scene.
The results are better, but you’ll notice that Betty’s footsteps don’t seem to move in
relation to the floor. This is because the current faceCamera settings are a rough
approximation of the camera move from the animated scene.
