MegaLights on Mobile: Pipe Dream or Reality? How Arm & Sumo Digital Made It Possible | Inside Unreal

Arm and Sumo Digital have teamed up to push mobile graphics into new territory, using Arm Neural Technology to help bring Unreal Engine MegaLights to Neural Dawn, a production-quality game that is the first to leverage this technology on mobile.

In this livestream, experts from Sumo Digital and Arm explore how Neural Dawn uses MegaLights with ray-traced shadows, and what it took to make this advanced Unreal Engine feature practical on mobile hardware. The session covers the creative and technical challenges behind bringing desktop-class visuals to mobile, including dynamic lighting, performance optimization, asset and lighting workflows. It also explores the role of Neural Technologies such as Neural Super Sampling and Denoising (NSSD) and Neural Frame Rate Upscaling (NFRU).

The team also discusses how close collaboration between game developers and Arm engineers helped unlock high-end visual features for production, while supporting the realities of mobile performance, power, and scalability.

Whether you’re an Unreal Engine developer, mobile game developer, graphics
programmer, or technical artist, this session offers a behind-the-scenes look at how Arm Neural Technology is helping make the next generation of mobile visuals possible.
