Unable to load empty meshes (dedicated server builds which strip meshes).

When attempting to open a bundle which contains meshes that have been 'stripped' by Unity at build time, the following error occurs.

[Warning] Unable to load object [Warning] Assets CAB-c34109ce312650cee7550ec680ca14a0 [Warning] Path <REDACTED>\linux_ds\meshes.bundle [Warning] Type Mesh [Warning] PathID 9223143378129672258 [Warning] System.IndexOutOfRangeException: Index was outside the bounds of the array. [Warning] at AssetStudio.Mesh.GetTriangles() in L:\GIT\AssetStudioMod\AssetStudio\Classes\Mesh.cs:line 1059 [Warning] at AssetStudio.Mesh.ProcessData() in L:\GIT\AssetStudioMod\AssetStudio\Classes\Mesh.cs:line 703 [Warning] at AssetStudio.Mesh..ctor(ObjectReader reader) in L:\GIT\AssetStudioMod\AssetStudio\Classes\Mesh.cs:line 680 [Warning] at AssetStudio.AssetsManager.ReadAssets() in L:\GIT\AssetStudioMod\AssetStudio\AssetsManager.cs:line 567 [Warning]

This can be repro'd by making a bundle for a dedicated server (windows or linux) with Enable Dedicated Server optimizations checked ON. (tested with Unity 2022.3)

Yeah, I see.
But what do you expect to see if it's just a placeholder asset?
A more relevant warning?

[coty-crg]

The real problem is the IndexOutOfRangeException, it needs to check if any data is available and if not just load the mesh as an empty mesh.

I don't want to actually load any mesh data in this case, of course. I just expect to be able to see the mesh assets are here (albeit empty). The exception stops it from loading properly.

You can check the latest build here: https://ci.appveyor.com/project/aelurum/assetstudiomod/branch/AssetStudioMod/artifacts
There will still be a warning, but an asset will load.
