illustration. (The second track area will be mostly green or all green in
the Track Summary.)
If the tracker fails to create a graph similar to the above illustration, three
actions might have occurred:
The tracker stays stuck at the same frame and the animation frame doesnt
advance
The tracker stops before the final frame
The tracker drifts off target
Whichever of these actions occurred, repeat the previous step, but this
time shorten the track boxs inner target box.
Importing tracking data
To reduce the repetition of tracking many more points in this lesson, you
import additional track points for the scene from a file we created for your
use in this lesson.
To import track data
1 Choose Track > Import Track Points from the Live menu set.
2 Navigate to the MayaLiveLessonData/points directory and open
fence_1.txt.
This imports the track point data for seven more points. (The track data
was created using the Track > Export Track Points operation.) Ordinarily,
you will not need to use the export and import operations; they are
intended for situations where you start over with a new scene but want
to retain track information.
Preparing to solve
Are there enough track points for you to solve the camera movement? Follow
these instructions to see how you make this decision.
