Hello, here are some steps you can try:
- Make sure you have the latest version of Cesium for Unreal. To find the updater, open the Epic Games Launcher and go to the Library tab. Below the version of Unreal that you are using for this tutorial, click Installed Plugins.
- Follow these instructions to set up Unreal for Oculus development. Since you already have Unreal installed, start at the section named, “Setup Unreal Engine for Android Development.”
- In Project Settings, go to Platforms - Android —> Build. Check Support arm64 and uncheck Support armv7.
