Sequencer provides the ability to tag tracks with metadata in order to support additional functions and behavior. Actors can have Tags assigned to them, and those tags can be referenced in Blueprints, which enables referencing Actors and tracks more generically. Tracks can also be placed into Groups, in order to manage their display and selection.
This page provides an overview of the Tags and Groups features in Sequencer.
Prerequisites
- You have an understanding of Sequencer, its Interface, and how to add Tracks.
- You have an understanding of Blueprint Visual Scripting.
Tags
Tags are metadata markers that you can assign to the Object Binding Track in Sequencer, and can be referenced by tag-based Blueprint nodes.
The quickest way to add a tag to a track is by right-clicking it, navigating to the Tags menu, and typing a name in the Add Tag field. Once done you can either press Enter or the Add (+) button to create the tag.
You can have more than one tag assigned to an Actor.
Once a tag is assigned, the Tags context menu will now show the list of tags added to the track. They can be toggled on and off by clicking them.
Binding Tag Manager
To view and manage your tags in Sequencer, you can open the Binding Tag Manager by clicking Open Binding Tag Manager in the Tags context menu. You can also open it from the toolbar’s Actions menu.
The Binding Tag Manager has two main areas:
-
The first area contains a list of all object bindings in the sequence, including any subsequences. Tags assigned to Actors are displayed next to them, and can be unassigned by clicking Delete (X) on the tag. New tags can be added by right-clicking a binding, typing in a name, and pressing Enter.
- The second area lists all existing tags for this sequence. Clicking Delete (X) will unassign it from all bindings.
Referencing in Blueprints
Binding Tags can be accessed in Blueprints by calling one of the "by Tag" Binding functions from Level Sequence Actors. You can use these functions to get the current binding or bindings of Actors with tags, rebinding those Actors, or resetting bindings.
"By Tag" binding functions can be found by right-clicking in the Blueprints graph or by dragging off from a Level Sequence Actor reference and locating them within Sequencer > Player > Bindings.
Most of the "by Tag" Blueprint functions have the following input pins:
- Target: The reference to the Level Sequence Actor.
- Binding Tag: The Tag name to look for.
- Actor: The Actor to bind, rebind, or add binding to.
- Allow Bindings from Asset: Disabling this will lock the sequence from further binding actions.
Groups
Tracks in Sequencer can be added into groups, which aid in quick selection and display filtering.
To create new groups and add tracks to them, right-click a single track or multiple tracks, and select Add to Group > New Group. This will open the Sequencer Group Manager and create the new group and add the tracks to it.
With a new group created, new tracks can also be added to that group from the Add to Group context menu.
You can also drag tracks from Sequencer’s outliner into the Sequencer Group Manager to add tracks to groups.
Group Manager
The Sequencer Group Manager is where you manage your groups and tracks that are assigned to them. If you are not creating a new group, you can open it by clicking Open Sequencer Group Manager in the toolbar’s Actions menu.
Management
Right-clicking in the Group Manager window will show the context menu, where you can create new groups, rename your group, delete groups, or Filter Groups.
Selection
You can quickly select the contents of a group by clicking the group header, or by clicking each group item individually.
Filtering
Clicking the Filter icon will filter all tracks out in the Sequencer outliner except for the tracks (and their children).
Clicking the Filters menu in Sequencer’s outliner will also display controls for enabling Group Filters.
