Platform: Apple visionOS with Polyspatial / Shader compilation error

[PanoCAST]

Thank you very much for developing this tool, we have used it extensively on multiple platforms, it works great.

Now, we would like to test it on Apple Vision Pro and place 3DGS elements in space using Polyspatial.
The scene works perfectly in the Editor, but when we build it it gives a shader error. Since your code
is already using Vulkan it maybe just a minor thing (also there are a few implementations already that
showcase 3DGS on the AVP, but not from Unity as far as I know)

Would you have any suggestion as to what the problem could be?

Shader error in 'Hidden/Gaussian Splatting/Composite': cannot assign to variable 'unity_StereoEyeIndex' with const-qualified type 'const int' at /Applications/Unity/Hub/Editor/2022.3.29f1/Unity.app/Contents/CGIncludes/UnityInstancing.cginc(187) (on metal)

Thank you for your help in advance

This is probably the same as various "it does not work in VR!" issues on other platforms, i.e. #17. I have exactly zero VR devices around, and no knowledge how to write shaders for it. If someone who knows would contribute solutions/improvements I'd take them, but I don't plan to do it myself.

@PanoCAST I encountered the same problem. Have you solved it?
