The Valley of the Ancient demo brings Unreal Engine 5’s flagship technologies to life, now fully streamed through the browser with Vagon Streams. It shows how a cinematic, open-world environment built with Nanite and Lumen can run interactively on any device, without a local GPU or installation.
This experience captures the scale and fidelity of next-generation 3D environments. Every texture, animation, and lighting change is processed in real time, delivering the full Unreal Engine experience directly from the cloud.
The Challenge
Large-scale UE5 projects like Valley of the Ancient are designed to push hardware to its limits. They use dynamic global illumination, dense geometry, and high-resolution textures that require powerful GPUs to render smoothly. For many artists, designers, or reviewers, simply opening the project is impossible without top-tier hardware.
Sharing such experiences has also been difficult. Pre-rendered videos lose interactivity, while local builds demand lengthy downloads and high system requirements. Real-time collaboration or live review was rarely practical outside a studio environment.
Vagon Streams removes that barrier. By running the Unreal Engine environment on high-performance cloud GPUs and streaming it through the browser, the same complex scene becomes instantly accessible to anyone. Teams can explore, interact, and test the project together, regardless of hardware or location.
The Impact of Cloud Streaming
Cloud streaming transforms how high-end Unreal Engine content is reviewed and shared.
For 3D artists and technical directors, it means full access to Nanite-level detail and Lumen lighting on any device. There’s no need to simplify geometry or reduce texture sizes for others to preview the project.
Production and creative leads can host live sessions where everyone views the same environment in sync. Camera paths, lighting changes, or level transitions can be tested collaboratively, without exporting or packaging new builds.
In training and research, instructors can demonstrate UE5 features directly in the cloud, letting students interact with real projects without needing high-end hardware.
By shifting rendering and computation to the cloud, Vagon Streams makes next-generation 3D projects as accessible as a website. It turns advanced Unreal Engine experiences like Valley of the Ancient into shareable, real-time environments that anyone can open, explore, and learn from.
