Hey there @R0ME0GA05! Welcome back to the community!

According to the 5.3 release page:

Mobile Ray Tracing Support on Android (Experimental)

UE 5.3 supports ray tracing for high-end Android devices running the Mobile Desktop Renderer. Supported mobile GPUs include:

  • Adreno 740
  • Immortalis-G715
  • Samsung XClipse Series

To enable mobile ray tracing:

  • Enable the desktop renderer for your project.
  • Enable ray tracing.
  • Add the following to your device profiles:
 [Android_Vulkan_SM5 DeviceProfile]  +CVars=r.Android.DisableVulkanSM5Support=0

This update also includes mobile indline shadow support for ray traced shadows, which only works with deferred shading.

This support is experimental and should not be used for production purposes at this time. However, we welcome feedback from users trying it out!
