App built with Unity/Cesium for AVP Not Launching

[smabdul-umich]

I am building an app in Unity for Apple Vision Pro (AVP). This app uses Cesium (Google 3D tiles), and I've followed all the steps in ProjectSpirare.

The app builds successfully in Unity and Xcode, however, when I launch the app on AVP, nothing happens. I have taken a short video of my setup in Unity. I want to put the user at the top of an air traffic control tower, and when they look around with the AVP, their view of the airport should turn around / adjust accordingly. Does any part of my setup here look incorrect? It is based off of the sample code provided in ProjectSpirare.

I am using:

• Unity version 2022.3.20f1
• Cesium version v1.15.5

I would be grateful for any help you can provide!

Could you build the SpirareBrowser-visionOS-3DMaps.unity scene in the repository and check if it displays correctly?
It’s difficult for me to provide support for issues related to scenes outside the repository.

Hello,

I have just attempted to build the SpirareBrowser-visionOS-3DMaps.unity scene, and still nothing displays. The only thing that happens is the lighting dims when I launch the app. I have made sure to input my API key (and set up my API for Google 3D tiles). Note that I built the app in VR mode, so I skipped the shadersubgraph steps.

Are you building in Metal mode instead of PolySpatial MR mode?
If so, could you try disabling the TilesetForPolySpatial component attached to the Tileset object?

[smabdul-umich]

Yes, I am building in Metal. I see the TilesetForPolySpatial.cs file, however, I do not see where it is used in the scene. The only mention of polyspatial I see in the scene is under "InteractionManagerPolySpatial and PolySpatialInputManager:

Sorry, I was mistaken.
TilesetForPolySpatial is attached to Tileset_GooglePhotorealistic3DTiles_PolySpatial.prefab.

[smabdul-umich]

No worries–I've disabled the TilesetForPolySpatial in the prefab, however the prefab doesn't appear in the scene:

Unfortunately, after building and running again, the same thing happens: the lighting dims, but nothing from the app displays.

I've also pasted a summary of output from the logs in XCode here. I'm noticing a lot of errors related to the render pipeline:
Pipeline (render) binary archive lookup failed for... followed by VisionOS Display Provider Destroying Textures, as well as metal compilation errors.

Would you get the same result in the Editor and in the Apple Vision Pro simulator?
Also, could you try a PolySpatial build?
