Unity3d adds OBB content in APK file for Meta Quest App with split activated + addressables + macOS O.S

Unity Engine

We are trying to create an app for Meta Quest, and to generate the APK + OBB, we are following the normal creation process with split binary enabled. When the build process finishes, Unity3D adds the content of the OBB into the APK and creates an OBB with a size of 2 KB, while the APK is 2 GB.

We are using Addressables 1.19.19 and Unity MacOS 2021.3.40f1.

Are there any files in Assets\StreamingAssets ? (Those should go in to OBB)

With Split Binary enabled, Unity puts first scene assets to apk and everything else into OBB. So, you might need to make your first scene smaller like a boot loader scene.

Hi,

Thanks for the response. We found that is a problem of Unity3d in mac version. We build the apk+obb moving the project to a PC-windows S.O. and build perfectly the apk with the correct obb size.
