Hi everyone,
I’m currently developing a mobile game using Unreal Engine 5 and trying to implement both Nanite and Lumen to enhance visual quality. However, when I build and test on mobile devices, I experience significant FPS drops and stuttering issues.
Has anyone here successfully optimized Nanite and Lumen for mobile projects? I’d really appreciate any tips, experiences, or best practices you can share!
Thanks in advance!
Hello there @david_vinij!
Checking around the community on similar inquires, the performance hit related to Nanite and Lumen is due both features not being fully supported for mobile, at the moment. Nanite is optimized for high-end PC builds and consoles, while Lumen has a limited application for Android Vulkan only.
The alternatives being proposed for mobile until nanite/lumen support is extended, would be to use static mesh LODs and baked lighting. Further methods for mobile optimization can be found here:
Make sure that mobile device will not melt screen from all those systems.
