In this section, we are going to add more functionality to the timeline by increasing its standard track selection, as in the following screenshot:

From this new extended track selection list shown in the previous screenshot, we will make use of Light Control Track.

It is possible to see a bigger selection from the drop-down list; this, however, is beyond the scope of this book. However, if you are interested, I will direct you to what to read to find out how to extend the list later on in this section.

In the next few sections, we will increase our tracklist with the aid of the Asset Store and download a free asset from Unity to increase our Timeline functionality. Then, we will animate the lights in our scene, which wouldn't have been possible before.
