Nvidia’s Breakthrough Unreal Engine Plugins for Realistic Digital Humans

Exciting Developments from Nvidia in Unreal Engine

Nvidia has just announced innovative advancements that will significantly enhance the realism of AI-driven characters resembling real humans. These remarkable features were presented at the recent Unreal Fest Seattle 2024, underscoring Nvidia’s dedication to advancing the digital environment.

Introducing New Plugins for Unreal Engine 5

During the event, Nvidia revealed a range of new plugins tailored specifically for Unreal Engine 5. These plugins fall under the Nvidia Ace suite, which includes cutting-edge technologies focused on digital human creation. This suite facilitates improvements in speech, intelligence, and generative AI-driven animation. With these enhancements, developers can efficiently create and implement MetaHuman characters on Windows PCs.

Highlighting the Audio2Face-3D Plugin

A standout feature among the new plugins is the Audio2Face-3D plugin, designed to enable AI-based facial animations. This tool ensures characters’ facial movements sync perfectly with spoken words, greatly enhancing the character’s realism. It is available for Autodesk Maya and provides developers with a user-friendly interface to streamline the avatar creation process.

Expanded Development Flexibility

This plugin includes comprehensive source code, granting developers the ability to build customized plugins that suit their favorite digital content creation tools. This flexibility is essential for developers seeking to optimize their workflows while retaining creative control over their projects.

Renderer Microservice and Animation Graph Enhancements

Nvidia has also introduced a new renderer microservice for Unreal Engine 5. This microservice utilizes Epic’s Unreal Pixel Streaming technology and is available in early access. It supports the Nvidia Ace Animation Graph microservice and Linux operating systems, significantly enhancing the realism and responsiveness of character movements.

Streamlined Character Streaming for Developers

With the addition of Unreal Pixel Streaming support, developers are now able to stream their MetaHuman creations across various devices. This enhancement not only improves accessibility and user experience but also plays a crucial role in reaching a broader audience by enabling high-fidelity character representations on any compatible device.

Bringing Life to MetaHumans with Ace Plugins

The Nvidia Ace Unreal Engine 5 sample project serves as a comprehensive guide for developers looking to integrate digital humans into their games and applications. This project enhances the functionality of Ace plugins, which now include:

• Audio2Face-3D for facial animation and lip-syncing
• Nemotron-Mini 4B Instruct for generating contextually relevant responses
• RAG for delivering contextual information

By leveraging these tools, developers can create a rich database of context-driven lore for their intellectual properties. This allows for the generation of timely, relevant responses with minimal latency, while triggering corresponding facial animations for MetaHuman characters within Unreal Engine 5.

Optimized for Peak Performance

Nvidia highlights that all these microservices are optimized to run efficiently on Windows PCs, ensuring low latency and minimal memory usage. This optimization is essential for developers aiming to deliver immersive experiences while maintaining high performance standards.

How to Get Started with the Latest Plugins

Nvidia is rolling out a series of tutorials to assist developers in setting up and utilizing the newly introduced Unreal Engine 5 plugin. These plugins will be available shortly. To get started efficiently, developers should ensure they have the right Nvidia Ace plugin and the Unreal Engine sample downloaded along with a MetaHuman character.

Utilizing Autodesk Maya for Enhanced Animation

For users of Autodesk Maya, game developers and technical artists can take advantage of high-performance animation features. Additionally, the Audio2Face-3D plugin simplifies the creation of high-quality, audio-driven facial animations for any character. Its user-friendly interface further ensures a smooth transition to working within Unreal Engine 5.

Accessing Essential Resources

To kick off projects in Maya, developers simply need to obtain an API key or download the Audio2Face-3D NIM. Furthermore, Nvidia’s NIM offers user-friendly AI inference microservices, streamlining the deployment of foundational models across a range of cloud or data center systems.

Developers should use Autodesk Maya versions 2023, 2024, or 2025 to access these resources. Additionally, they can visit the Maya Ace GitHub repository for the plugin, gRPC client libraries, testing assets, and sample scenes, providing all the tools they need to innovate with Audio2Face-3D.

Cloud Deployment and Advanced Animation Graph Microservice

For developers looking to deploy digital human characters through the cloud, Nvidia’s latest Unreal Engine 5 renderer microservice solves the challenges of streaming high-fidelity characters. This microservice enhances the Nvidia Animation Graph Microservice and is currently accessible in early access for Linux operating systems.

Creating Advanced Animation Systems with Ease

The Animation Graph microservice empowers developers to establish intricate animation state machines and blend trees. This flexible, node-based system effectively manages animation blending, playback, and control.

Benefits of Cloud Streaming Technology

The new renderer microservice harnesses pixel streaming technology, utilizing data from the Animation Graph microservice. This setup allows developers to operate their MetaHuman characters on cloud servers and stream rendered frames and audio to any browser or edge device through WebRTC.

Apply for Early Access to New Features

Developers interested in exploring the new Unreal Engine 5 renderer microservice, which supports the Animation Graph microservice for Linux OS, can apply for early access. This initiative reflects Nvidia’s ongoing commitment to empowering developers in creating engaging and realistic digital experiences.
