In the Timeline Editor window, we can insert and organize Layers into tracks, play them back, and much more.

Good to know: On the bottom right of the Timeline Editor Window, there are two opacity values, one indicating Fade and the other indicating Volume.

Timeline Management

You can switch between existing Timelines in three different ways:

  • by clicking them from the Timelines list on the left side of the Timeline Editor window,

Good to know: You can hide the Timelines list by left-clicking the bottom left icon in the Timeline Editor window and disabling Show timeline list box checkbox.

  • by clicking on them in the Timelines window,

  • by clicking on their Sections in the Timelines window.

Track Management

Each Timeline consists of tracks where we can place Layers.

Add or Delete Tracks

To adjust the number of tracks in a Timeline, use the controls in the bottom left corner of the window.

Track Options

There are a few track options:

  • Track height enables you to see a live Preview of the Texture rendered by the active layer in the track,

The preview only appears if there is at least one active Render texture node in the layer.

  • Disable icon stops all layers in the track from executing, even if an active Playhead is overlapping them,

  • Solo icon disables all layers from all other tracks, so they stop executing, and

  • Lock prevents you from moving or manipulating all layers in the chosen track.

Timeline visualization

In the bottom left corner of the Timeline Editor, you will find additional options for navigating and customizing the Timeline.

You can customize it further using:

  • Timeline Editor menu to add new or delete the existing Timelines, manipulate Playhead behavior and Play options,

Good to know: When Scroll timeline window during play is enabled, the Timeline Editor will automatically scroll when the Playhead is playing the Timeline. Scrolling will start only when the Playhead reaches the center of the Timeline.

  • Zoom in and Zoom out to change the scale of the Timeline while keeping the Playhead centered,

  • Focus Playhead to adjust the view of the Timeline, so that the Playhead is in the center of the window, and

  • Jump to button to enter the desired spot on the Timeline where you would like the Playhead to jump.

Rearrange Tracks

Similar to how you can rearrange Timelines in the Timelines window, you can also rearrange Tracks in the Timeline Editor window.

To rearrange a Track, drag it to the desired position using the arrow.

Rendering Order

Good to know: When stacking multiple Layers on top of one another in the same Timeline, the bottom Layer will be rendered first, ending with the topmost Layer. If all Layers are rendering content to the same mapping, the topmost Layer's content will appear above the content of all Layers on the mapping.

Rearranging Tracks affects the rendering order in which the Tracks will be rendered and displayed.
