I accidentally deleted a Cesium3DTileset in one of the sample levels (though it doesn't matter which), and tried to undo it. But this messes up a lot.
Firstly, the console gets spammed with these error messages:
This Mesh Collider is attached to GameObject at path 'CesiumGeoreference/Cesium World Terrain/[url]/Mesh 0 Primitive 0' with Mesh '' in Scene '01_CesiumWorld', but the mesh doesn't have any vertices.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
Then, as tiles attempt to reload, many of them will appear purple (indicating a material with errors)...
... and some of them will appear un-georeferenced. In this screenshot, the purple streaks in the sky are floating tiles.
I imagine that undoing the deletion is pretty disastrous for the state management of Cesium3DTileset, but I believe it's because the delete operation is recording the deletion of the child game objects -- even those marked HideAndDontSave. So when I undo the operation, it adds back all of those game objects. This prevents the tileset from properly cleaning up when it is disabled and reenabled.
I don't know if this can be prevented, but hopefully there's a way to intercept the undo operation and prevent the tiles from being reattached?
