Just wanted to highlight what looks like a current bug.

A Cesium Blueprint error keeps appearing in UE5 Editor 5.7.4

Hey @JojoAEC, no worries, this is a known cosmetic warning, not a functional bug. UE 5.6+ deprecated the `RunningThreadedRequestLimit` ini keys, and the Cesium plugin still references them in its bundled `Engine.ini`.

It’s tracked on GitHub: [cesium-unreal#1723](https://github.com/CesiumGS/cesium-unreal/issues/1723)

The warning won’t affect the plugin’s functionality. It’ll most likely be cleaned up in a future Cesium for Unreal release.

Cheers!
