Rapport Studio Release Notes

Release 30th June 2025

Rapport Plugin Release – Unreal Engine Integration & Enhancements

Release Date: 30th June 2025
Release Code: RT-3127

Updates

The latest release of the Rapport Unreal Plugin introduces robust support for Unreal Engine 5.3 through 5.6, plus a suite of functional enhancements to provide greater flexibility, control, and integration capabilities within Unreal projects.

This update is part of our ongoing effort to make AI-driven character experiences in Unreal more powerful, modular, and production-ready.

What’s New

Full UE5.3 – UE5.6 Compatibility

Now tested and validated on Unreal Engine versions 5.3, 5.4, 5.5, and 5.6.

Expanded Audio Input Support

Give your projects greater input flexibility with:

• New Audio Input Sources:

  • Audio Asset

  • Pixel Streaming

• Custom Audio Source Support

• Audio Input Muting Functionality

These upgrades allow broader use cases and more dynamic voice experiences within Unreal environments.

Enhanced Runtime Control

Two new control functions enable greater programmatic control over runtime behaviour:

• Set Mode

• Set Modifier

• Set Engine

These functions give developers fine-grained control over character state and dialogue execution paths.

New Event Hooks for Real-Time Feedback

Gain deeper visibility into your project flow with event callbacks for:

• STT Text Output (captured user speech)

• AI Response Text

• Audio Response Start & End

These hooks allow integration with other systems or custom UI/logic triggers.

Customer Hosted Content using Idle Configuration

A step toward greater interactivity and external control, with:

• Request Character Speech – Trigger a character to speak manually

• Stop Character Speech – Interrupt or cancel a character's current audio playback

This enhancement aligns with the Idle AI Mode, enabling more scripted or externally triggered behaviours.

Developer Toolkit Highlights

Bug Fixes & Improvements

• Minor stability and performance optimisations across the plugin

• Quality-of-life refinements in Rapport Studio for improved usability

Backend Changes (In Progress)

We’ve made foundational backend updates to support Linked Services, our upcoming feature for centralised TTS, STT, and AI provider credential management. This feature will be exposed in a future release.

Coming Soon

• Linked Services (Centralised Credentials)
  Manage your TTS/STT/AI provider credentials from one unified place across all projects.

• Advanced Settings Redesign
  Refined experience for power users looking to configure STT/TTS/AI with precision.

• Voice Logic Improvements

New Features

Rapport Unreal Engine Plugin

The Rapport Unreal Plugin (RUV) is an Unreal Engine plugin that connects your Rapport project and drives character performances.

Through a direct connection between your Rapport project and Unreal Engine, the plugin enables real-time character animation and communication.

How It Works:

• When someone speaks into their microphone, the plugin captures their voice and sends it to Rapport.

• In response, Rapport returns synchronized speech and animation data.

• This data drives your character’s movements and facial expressions, ensuring that the character’s speech and performance match the spoken words.

By using the Rapport Unreal Plugin, you can create lifelike, interactive digital characters for games, simulations, and virtual experiences.

Updates

Change to the Rapport Studio Workflow

Rapport Studio now follows a clear, structured four-step workflow.

🔗 Project Creation Workflow

New Workflow Steps:

Settings – Define the project name and type.
Choose Application Type – Determines:

✅ Customization options available in the Design phase.
✅ Preview and testing workflow in Demo & Integrate.
✅ The final integration process based on the selected platform.
Design – Customize characters, voices, and settings based on the chosen application type.
Demo & Integrate – Finalize, test, and prepare for deployment.

On the Design page, the ability to change background colours is now restricted when a Metahuman character is chosen for a Web-type application.

Application Type Lock: Once an Application Type has been selected during the Project Creation Workflow, it cannot be changed at a later stage, this is to maintain consistency in the design and integration process.
