Maximum Build Size and Optimization for visionOS?

Unity Engine

Hello,

I’m looking for information regarding the maximum size of a build that can be uploaded to the App Store for a visionOS application.
I couldn’t find any official documentation—sometimes I see 4GB, other times 8GB.

If I exceed the maximum size, are AssetBundles compatible with visionOS?

Additionally, another question about build size: I created an empty project containing only the PolySpatial packages. When building, the folder containing the Xcode project is 1.5GB, and the installed build on the headset is nearly 475MB. Why is a literally empty project so large? Is it possible to reduce this size?

Thank you very much.

Mostly yes; the one caveat is that, in RealityKit mode, shaders can’t be loaded from asset bundles. All of your shaders must be present in the base build.
