Cut Out the Guesswork With New Unreal Engine Performance and Packaging Samples

We’re shaping a future where developers of every technical background can build their best work on Meta Horizon, no matter which tools or engines they prefer to use. Whether you build in Unreal Engine, Unity, Android, or for the web, new tools and enhanced workflows make it easier than ever to create, optimize, and grow in VR.

From Ghosts of Tabor to Skydance’s BEHEMOTH, Unreal has helped bring some of the most popular apps on Meta Horizon to life. But, amid recent major updates, you might have missed some tools we’ve built to improve the Unreal Engine developer experience.

Our new Unreal Engine samples are designed to help you tackle common pain points, including optimizing performance, streamlining workflows, and packaging your projects. Together, these samples can save you significant time by removing a lot of the guesswork from core aspects of your development process.

Here’s a closer look at two new Unreal samples that make it easier to build high-fidelity, performance-optimized experiences for Meta Horizon OS.

The Unreal Performance Settings Demo reveals exactly how different configuration choices impact performance on Meta Quest devices to help you find the sweet spot between visual fidelity and smooth runtime behavior.

The sample contains interactive controls for settings like render scale, dynamic resolution, fixed foveated rendering, MSAA (multisample anti-aliasing), CPU/GPU performance levels, Application SpaceWarp, and passthrough. Beyond adjusting these settings, you can also stress test CPU and GPU usage to see exactly how each tweak impacts performance and fidelity.

What makes this resource especially valuable is how it demystifies performance tuning by visualizing trade-offs in a practical setting. Developers can experiment in real time to see how a more aggressive render scale might tax the GPU, or how enabling fixed foveated rendering changes performance without a huge hit to perceived visual quality.

By leveraging this demo, you have a sandbox to test performance decisions before they become an issue and eliminate trial and error in mastering settings that are critical to delivering top-tier VR experiences.

One of the biggest challenges we’ve heard from Unreal developers is managing large projects that exceed Android file size limits. The Unreal OBB Sample tackles this challenge head-on by giving you a clear blueprint for packaging and distributing big projects efficiently.

The sample walks through how to split your Unreal Engine project into multiple OBB (Opaque Binary Blob) files, map your content chunks, and upload them through the Meta backend so players can download exactly what they need. It includes working examples, configuration details, and automation scripts that simplify what’s historically a complex process.

After engaging with the sample, we’re confident that you’ll be able to spend less time troubleshooting packaging errors and free up more time to focus on iterating and enhancing your app experiences. Whether you’re working on a large-scale VR app or experimenting with content updates, this sample gives you a reliable foundation for scaling your Unreal projects, reducing friction, and building high-quality experiences faster.

We hope you find these samples and resources helpful. If you run into issues or want to let us know how we can improve, let us know via the Feedback Tool in Meta Quest Developer Hub.
