I am writing to formally request a strategic expansion of Unreal Engine’s mobile capabilities: the implementation of a Native Lightweight Mode and a Non-Game App Framework.
While Unreal Engine is the undisputed leader in high-fidelity mobile gaming, there is a growing community of developers—including myself—who wish to leverage Unreal’s robust C++, Blueprint, and UMG systems to build general-purpose utility, enterprise, and service-oriented applications.
Currently, the engine’s “game-first” architecture presents significant barriers for non-game mobile apps, specifically regarding battery consumption and package size.
Requested Features
-
Event-Driven Rendering (On-Demand Ticking): A mode where the engine ceases the constant 60/120 FPS render loop. The engine should only redraw the frame when a UI state change or user input is detected, bringing battery efficiency in line with native iOS/Android frameworks.
-
Modular Engine Stripping: A “UI-Only” build target that allows developers to completely exclude the 3D rendering pipeline, physics engine (Chaos), and audio engine. This would ideally reduce the base APK/IPA size from 100MB+ to a competitive 20–30MB range.
-
OS Utility Classification: Options to package the application as a standard “Utility” rather than a “Game,” ensuring the OS manages background processes, notifications, and power states appropriately for a non-gaming environment.
-
Enhanced Native Bridge: Improved out-of-the-box support for mobile OS features such as native system dialogs, deep-linking, and background services without requiring extensive custom C++ workarounds.
The Use Case
The demand for high-performance interactive dashboards, industrial monitoring tools, and enterprise AR applications is shifting. By providing a “Non-Game” framework, Epic Games would empower developers to build “all-in-one” business solutions that carry the visual polish of Unreal but the efficiency of a native utility app.
This move would position Unreal Engine as a direct and superior competitor to frameworks like Flutter and Unity’s UI Toolkit in the enterprise and HMI (Human-Machine Interface) markets.
Thank you for your time and for the incredible work you do in pushing the boundaries of what is possible on mobile hardware. I look forward to hearing your thoughts on this direction.
Best regards,
