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.
