Unity Custom APK Not Rendering in 3D on Leia Lume Pad 2

Lume Pad
1

Hello,

I am developing a custom Unity APK for the Leia Lume Pad 2 using the latest Leia SDK (v3.2.18). The SDK components, including LeiaDisplay and HeadTrackingService APKs, are installed on the tablet.

Issue:
I have followed the standard steps to create and build the ModelViewer sample scene provided in the Leia SDK. However, when I run the APK on the Lume Pad 2, the scene is only displayed in 2D, and it does not switch to 3D lightfield mode as expected.

Steps I’ve Taken:

  1. Imported Leia SDK (v3.2.18) into Unity.

  2. Opened the ModelViewer sample scene.

  3. Built the APK using Android Build Settings.

  4. Installed the APK on the Lume Pad 2.

Expected Behavior:
The scene should render in 3D lightfield mode on the Lume Pad 2.

Actual Behavior:
The scene displays only in 2D, not switching to 3D lightfield mode.

Questions:

  • Is there any additional configuration required in Unity Player Settings, such as for Graphics APIs or XR settings?

  • Do I need to manually enable Lightfield rendering in the code for custom APKs?

  • Are there any specific device permissions or SDK components I need to initialize for 3D output?

Please let me know if I am missing something in the configuration. Any guidance or advice would be appreciated.

Thank you!
