Google 3D Tiles switching to various map "versions" in Cesium/Unreal

Cesium for Unreal
1

I’m building out a construction site in 3D using Unreal Engine, with the surrounding area utilizing Cesium’s Google Maps Photorealistic 3D Tiles. This is an ongoing project, and at some point Google’s satellites rescanned and updated their model of my area.

The Issue:
The native web versions of Google Maps and Google Earth currently show the updated, more detailed model. About a few weeks ago, this updated model was being fed into Cesium/Unreal Engine which was fine since its higher fidelity. Then it suddenly reverted to the previous version. Yesterday it briefly updated to the newer, more detailed model for an hour or two, then reverted back again.

I’ve tested this with a completely new Unreal project at default settings, and it still loads the “previous/older” version of the map data.

My Questions:

  • Is there a setting to force an update to pull the latest data from Google Maps?

  • Is this data being fed directly from Google, meaning I’m at the mercy of whatever they’re sending to Cesium and when they decide to “push” the latest version?

  • Is there a workaround for this? I cannot share the specific location due to business confidentiality.

  • Can I freeze the map data at a specific “version” so it doesn’t update, allowing me to properly blend my Unreal Engine assets with consistent map data?

Has anyone else experienced this issue?

I moved this to the “Cesium For Unreal” section. It’s more likely to receive the right attention hiere.

A quick note: Cesium For Unreal creates a cache file that may contain downloaded tiles. But when you describe that it switches between the older and the newer version, that might not be the reason. Although it appears unlikely that Google would switch between different tile versions for an extended period of time, eventually, the data is coming from Google, and ‘whatever it is, it is’ - I think there is no way to enforce a certain “version” (but would like to stand corrected here - it’s a request that came up several times…)
