cesium unity plugin on arch linux

[2tata]

Hi, first of all thanks for this amasing software!

I got an issue installing cesium in unity on linux.

to my system: 6.10.10-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 12 Sep 2024 17:21:02 +0000 x86_64 GNU/Linux

unityhub version 3.9.1 --> https://aur.archlinux.org/packages/unityhub

I installed the 2022.3.48f1 editor version

### first attempt

I created a new project (3D core).

under "services" -> "gerneral settings" -> "Package Manager" I added following:

Cesium
https://unity.pkg.cesium.com
com.cesium.unity

then I installed the cesium plugin in version 1.13.0

The consol log give me some errors:

Library/PackageCache/[email protected]/Runtime/Cesium3DTile.cs(2,7): error CS0246: The type or namespace name 'Reinterop' could not be found (are you missing a using directive or an assembly reference?)

seems that Reinterop for dotnet is not coming with that repo plugin.

### second attempt

I followd the instructions here: https://github.com/CesiumGS/cesium-unity/blob/main/Documentation~/developer-setup.md

installed: extra/dotnet-sdk 8.0.8.sdk108-1 (85.3 MiB 300.0 MiB) (Installed) extra/nasm 2.16.03-1 (341.2 KiB 2.4 MiB) (Installed)

dotnet --version 8.0.108 cmake version 3.30.4

cloned cesium-unity-samples

then cesium-unity inside it.

in cesium-unity-samples/Packages/com.cesium.unity i called:

[<user> com.cesium.unity]$ dotnet publish Reinterop~ -o .
MSBuild version 17.8.5+b5265ef37 for .NET
  Determining projects to restore...
  All projects are up-to-date for restore.
  Reinterop -> /home/<user>/cesium-unity-samples/Packages/com.cesium.unity/Reinterop~/bin/Debug/netstandard2.0/Reinterop.dll
  Reinterop -> /home/<user>/cesium-unity-samples/Packages/com.cesium.unity/

got the message:

DllNotFoundException: CesiumForUnityNative assembly:<unknown assembly> type:<unknown type> member:(null)
NotImplementedException: The native implementation is missing so OnValidate cannot be invoked.

did:

cd cesium-unity-samples/Packages/com.cesium.unity/native~
cmake -B build -S . -DCMAKE_BUILD_TYPE=Debug

run into following error:

[<user> native~]$ cmake -B build -S . -DCMAKE_BUILD_TYPE=Debug

(this is maybe interresint for you guys)

work around it with following:

cd /home/<user>/.ezvcpkg/2024.07.12
cp triplets/x64-linux.cmake triplets/x64-linux-unity.cmake

run the first cmake call again:

now in unity i added the cesium-unity-samples project but with 2022.3.48f1 editor version (the 2021 one seems not work on arch anymore). logedin into cesium ion. Then added a Blank 3D Tiles Tileset on the gameobject Cesium3DTileset I switch to url and use my maps api url https://tile.googleapis.com/v1/3dtiles/root.json?key=<my key>

then I get following error:

[2024-10-01 23:49:28.695] [error] [TilesetJsonLoader.cpp:697] Error when parsing tileset JSON, error code Invalid value. at byte offset 0

          pLogger,
          tileUrl,
          tilesetJson,
          tileTransform,
...

i change the error message parameter to tileUrl wich gave me the uri provided by the maps google api

https://tile.googleapis.com/v1/3dtiles/datasets/CgA/files/UlRPVEYubm9kZWRhdGEucGxhbmV0b2lkPWVhc<some removal>PTYsaW1hZ2VyeV9lcG9jaD0xMDA5LGFsaWdubWVudF92ZXJzaW9uPVJPQ0tUUkVFXzk4OF9HT09HTEVfREFUVU1fMjAyNDA3MDRUMDc1M1pfZ2VuZXJhdGVkX2F0XzIwMjQwOTE3VDEyMDha.glb

this is a valid glb compressed Json file wich I checked with https://github.khronos.org/glTF-Validator/

the google maps API sayes somethng from:

  "extensionsUsed": [
    "3DTILES_content_gltf"
  ],
  "extensionsRequired": [
    "3DTILES_content_gltf"
  ]
}

which I didnt investigated further.

It seems that the cesium plugin have an Issue decompressin glb files.

Does you have any idea how i can fix it?
