Objective: Understanding how to utilize control tracks!
What is a Control Track is in essence a track that controls other Timelines. You can have more than one in a particular scene. Which is great because we can nest Timelines into other Timelines. They can also control objects as well.
What do we need to do to make this happen? We need another Timeline. Create a second Timeline. Create an object to child under the Timeline and create a quick animation.
Now you can go into your first Timeline and create a control track. The control track can now take in the second Timeline.
Now, when you play back this sequence you can now have your Timeline start playing here.
When you begin playing your Timeline you will notice that the second Timeline is not enabled until the sequence enables the Timeline.
So, in review, control tracks are used to control multiple Timelines in one sequence to create really complex Timeline animations.
