No terrain in scene on Unreal 5.1 in Linux

Cesium for Unreal
1

I’m unable to get terrain of any kind to show up in Unreal 5.1.1 using Cesium plugin 1.30.1 on Alma 8 Linux. The only thing I see in the editor viewport is the bare flat white/blue plane. I’ve also ensured that Realtime is enabled and I am not accessing the computer remotely.

I’ve compiled both Unreal and the Cesium plugin from source, tried both the quickstart tutorial as well as the cesium sample project. I’ve confirmed that the tokens are valid and the token troubleshooting window is all green. I also see no errors in the output window.

Any ideas on why this could be or other steps I could perform to troubleshoot would be appreciated, thank you.

Maybe share a screenshot with us? I’m not sure what you’re referring to with “the base flat white/blue plane” so it might help to see it.

FWIW, we include Linux binaries in our releases for UE 5.2 and 5.3 that we distribute on GitHub. So if you can upgrade to 5.2, it might save you a lot of trouble.
