Unreal 5.7.4 Cesium Startup Error

Cesium for Unreal
1

Getting this error when I open my project. It doesn’t affect functionality or packaging, but I’d like to figure out a fix in case it causes issues down the line. This is a blueprint-only project.

LogClass: Error: EnumProperty FCesiumMetadataPropertyStatisticValue::Semantic is not initialized properly. Module:CesiumRuntime File:Public/CesiumFeaturesMetadataDescription.h

LogAutomationTest: Error: LogClass: EnumProperty FCesiumMetadataPropertyStatisticValue::Semantic is not initialized properly. Module:CesiumRuntime File:Public/CesiumFeaturesMetadataDescription.h

Hey @Setaro_House, thanks for reporting this and welcome back to the forum!

Have you recently updated UE versions? UE5.7.4 introduces stricter property validation which may be causing this.

Can you try updating to the latest Cesium for Unreal plugin if you aren’t already and see if this resolves?

I agree that this is probably cosmetic, however if you update to/are already on the latest Cesium for Unreal Plugin, then I can log this as a bug on github

Hello!

Yes I recelty moved from 5.6.1 to 5.7.4 and am on the most up to date version of Cesium at least according to the Epic Launcher. I did notice similar validation constraints after having to refactor an old mobile plugin to inlcude a bunch of explicit initializations.

This particualr Ceisum one is flagged as a “red” error in the Log at startup. Normally this would stop compilation but I guess since I’m not using that part of the service right now, the compiler never has to touch it which is why I don’t see it come back.

Let me know if you need anything else thanks!

Hi @Setaro_House,

Thanks for confirming those details, that’s really helpful.

Before I can log a bug we need to know what Operating System you’re on, a screenshot of the error/a copy of the log, and concrete reproduction steps starting from a fresh UE5.7.4 project using the Unreal Samples (available on FAB) as a baseline.

Let us know how that goes! Cheers

Steps I did to reproduce:

  1. Launch a fresh UE 5.7.4 project.
  2. Select template type: AR Handheld
  3. Error shows up in the startup log

I didn’t even need to load any sample projects; this just appears when the plugin gets enabled.
