ΒΆ Unreal Setup (FrostLINK)
If you are implementing voice-over or narrative audio directly into Unreal Engine 5.6+, you'll want to install the Frostune Narrative Importer plugin.
This plugin enables FrostLINK, allowing FTVO to communicate directly with your Unreal project for automated voice asset import, updates, container creation, and cleanup.
1. Download the Unreal Plugin
Go to your Frostune Library:
https://frostune.com/library
Download the file:
FrostNarrativeImporter_Unreal.zip
This archive contains a standard Unreal Engine plugin folder.
2. Install the Plugin in Your Unreal Project
-
Locate your Unreal project root folder (the one containing your .uproject file).
-
If it doesn't already exist, create a folder named: Plugins
Extract FrostNarrativeImporter_Unreal.zip into the Plugins folder so you end up with:
Tip: This is a project plugin, not an engine plugin. Keeping it project-local avoids engine version conflicts and keeps source control clean.
3. Enable the Plugin in Unreal
-
Open your Unreal project.
-
Go to Edit -> Plugins.
-
Search for "Frostune" or "Frost Narrative Importer".
-
Enable the plugin.
-
Restart the Unreal Editor when prompted.
-
After restart, the FrostLINK endpoint becomes available inside the editor.
4. Verify FrostLINK Is Active
Once enabled and restarted, FTVO can now:
- Push new voice lines
- Update changed dialogue
- Delete obsolete assets
- Keep Unreal assets in sync with your FTVO project
- Automatically create and manage audio containers
You don't need to manually configure anything for basic usage, FrostLINK is automatic.
5. Using FrostLINK from FTVO
In FTVO:
-
Set your Unreal destination root
(for example: /Game/Audio/Voices) -
Use Unreal Push from FTVO
-
Choose Dry Run (optional but recommended) to preview changes
-
Run a full push to import or update assets
FTVO will automatically:
- Import WAV files
- Create or update SoundWave assets
- Maintain deterministic and stable naming
- Remove assets that no longer exist in the script (diff-based cleanup)
- Create and update Single, Random, and Sequence containers based on scene configuration
- Keep container structure in sync as dialogue evolves
6. Blueprint Integration (Play FTVO)
When the plugin is enabled, Unreal also exposes the Play FTVO Blueprint node.
This node allows you to:
- Trigger FTVO-managed voice lines directly from Blueprints
- Play single lines or container-based dialogue (random / sequence)
- Keep gameplay logic decoupled from raw asset references
The node is immediately available in Blueprint graphs once the plugin is enabled, no additional setup required.
Notes & Best Practices
- Works with UE 5.6+
- Safe to re-run (idempotent imports)
- Designed for large narrative projects (thousands of lines)
- Source-control friendly (no editor hacks, no manual steps)
If Unreal is not running or FrostLink is unreachable, FTVO will clearly report it before attempting any destructive operation.
