Tracks

There are numerous types of tracks you can use with Odyssey.

Track list	Asset type
	Level Sequence
	Shot Sequence
	Board Sequence

Note

This documentation is a summary of the most used tracks in the Sequencer. We advise you to read Unreal Engine 5.4 guide to know more about tracks.

Actor to Sequencer

This option will bind an Actor from the Level to the current Level Sequence:

By the way, when using a Media Plate, you will be asked this:

Answer “Yes” if you want the animation from the Media Plate to be played at a specific moment. Answer “No” if you want the animation from the Media Plate to keep the Autoplay mode in the Level.

When working with a Board Sequence or a Shot Sequence, the option “Actor to Sequencer” does not exist. However, you can still use un Actor from a Level with a simple drag and drop from the Outliner to the Timeline area.

Note

When working with Board and Shot Sequences, the types of Actors are limited. For instance, you can use Static and Skeletal Meshes, but you cannot use Blueprints.

Folder

Folder can be used to organise various tracks together.

Audio Track

Before using an Audio Track, you will have to import the sound in the Content Browser. Then you can simply drag and drop the Audio Track into the Sequencer.

Note

You can only use WAV files in 16bit. MP3 files are not allowed. We advise you to read Unreal Engine 5.4 guide to know more about Audio Tracks.

Camera Cut Track

Camera Cut Track shall be used to bind a CineCamera Actor to a Level Sequence.

When working with a Shot Sequence, Camera Cut Track are automatically created when adding a camera. (Read the lesson about Storyboard Sequences)

Shot Track

Shot Track will allow you to use a sequence within another Level Sequence that is used as a “Master” sequence. Using only Shot Track will be then quite similar to an editing software, since you will have the possibility to organise the order of your sequences or change their time scale to be played faster or slower. And like an editing software, the sequence played in the viewport is the upper track.

The icon “Lock Camera” will allow you to automatically “jump” from a CineCamera Actor view to another.

Note

By default, only Level Sequences can be added in Shot Tracks. To add a Board or Shot Sequence, you must first add a Shot Track, then drag and drop the Board / Shot Sequence in the Timeline area.

Note

For more details about Shot Tracks, we advise you to read this documentation on Unreal Engine 5.4.

Subsequence Track

In large-scale cinematic productions, it is necessary to have multiple artists working on the same shot at the same time (3d animation, lighting, VFX, camera action, etc.) The Subsequence Track enables this type of workflow by allowing additional sequence assets to be contained within the same sequence. Subsequences can also be used to organize your scene so that repetitive tracks and content are partitioned away into their respective disciplines’ subsequence.

Note

Just like Shot Track, only Level Sequences can be added in Subsequence Tracks by default. To add a Board or Shot Sequence, you must first add a Subsequence Track, then drag and drop the Board / Shot Sequence in the Timeline area.

Note

For more details about Subsequence Tracks, we advise you to read this documentation on Unreal Engine 5.4.

Fade Track

Fade Track is used to create fade in and out on a scene thanks to keys.

Note

For more details about Fade Tracks, we advise you to read this documentation on Unreal Engine 5.4.

Level Visibility Track

Note

To better understand this section, you must know what a Level is and how to use multiple Levels at the same time. To do so, please read this lesson about Levels.

Level Visibility Tracks are absolutely necessary to combine or use several 3d environments at the same time. It can be used to:

• switch between several separated environments which belong to the same scene (example: a character moves from a house to a train station);

• combine Levels with additional actors (example: an empty Level with a rough storyboard and a Level with the actual 3d scene).

Level Visibility Tracks are also mandatory before rendering a sequence as a video file.

Note

You will find a use case for Level Visibility Tracks in the lesson about Working with multiple Levels.

Media Track

Originally, Media Tracks were used to display an external image sequence or video into a Level. The process needed:

• A Level with a Static Mesh (Plane, Cube…)

• An asset “Media Texture”

• A Material using this Media Texture and applied to the Static Mesh

• An asset “Media Source” to find the external source as an image sequence or a video file

• A Level Sequence with a Media Track, whose the properties set what Media Texture and what Media source are in use

The whole process is explained in details in Unreal Engine 5.4 documentation.

With Unreal Engine 5, Epic Games introduced a new type of actor named “Media Plates” which is much easier to use, especially for video footage. To create a Media Plate:

1. Drag a video footage and drop it into the Content Browser to create an asset Media Source.

2. Drag this asset Media Source and drop it into the Level. It will create a Media Plate that looks like a black Plane Actor.

3. In your Level Sequence, create a Media Track, then bind it to the Media Plate.

In Odyssey, Animation assets are considered as Media Source, which means you can easily drag and drop your 2d animation in a Level, and bind it to a Level Sequence:

Note

Note Tracks

Note Tracks can be used with Board and Shot Sequences only.
