Apple Shake 4 - Manual (Page 495)

Chapter 18 Compositing With the MultiPlane Node 495
The data from the .ma file appears in the Viewer as a cloud of points.
The camera or tracking data populates the parameters of the Camera tab, and a new
camera appears at the bottom of the renderCamera pop-up menu.
Important: Many 3D applications export camera paths with timing that begins at
frame 0. Shake scripts begin at frame 1, which can result in a one-frame offset. To
correct this, edit the timing of each camera path point as described in “
Editing Locator
Point Data ” on page 499. (This is not an issue for 3D tracking point clouds—they have
no timing data associated with them.)
Once a 3D camera path or tracking data cloud has been imported into the MultiPlane
node, you can attach the layer that produced the tracking data to the camera. Doing so
forces the attached layer to follow along with the camera as it moves to conform to the
tracking data. As a result, the attached layer itself doesn’t appear to be moving in the
camera output. You can tell that the correspondence is correct if the imported tracking
points conform to the matching features within the attached layer.
