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.
