Tool for upgrading dataset from 1.0.0 to 1.2.0?


We have a thread on the Unreal subforum and Agallegos has probably solved the case. The dataset we’re trying to bring into Unreal is of an older kind, and thus it’s incompatible with the UE plugin. A suggested solution is to upload the data to Cesium Ion, as this would probably handle the conversion.

However, the dataset is for the entire country of Norway, and it’s self-hosted by our data provider. It’s probably way to big for Ion.

Are there any tools for updating the data to a newer version, or will they have to re-tile their data in order to make it work for us in Unreal?

Hi @Tore_Holmem,

Thank you very much for reaching out to the community! Any suggestions for some next steps @agallegos?


Hi @Tore_Holmem,

Apologies for not replying sooner. As of the 1.13.0 release of Cesium for Unreal, the dataset you are trying to load should now be compatible. The release should be live on the Epic Marketplace soon, but if you want to download it earlier, you can download 1.13.0 from GitHub. Please chime in on the other thread if your dataset is still not loading in Unreal.

This doesn’t resolve your title question - we do not currently have a tool for upgrading quantized-mesh terrain datasets other than retiling via Cesium ion or our on-premise 3D tiling solutions. However, hopefully this is no longer pressing now that support has been added in Unreal for these tilesets.

Let me know if you have any further questions.


Thank you for your response and for the updated options for such datasets!

Kind regards, Tore
