Error Loading Cesium after updating

I’m trying to load up Unreal Engine 4.26.2 downloaded straight from unreal using their launcher

I’ve installed the Cesium add on Cesium for Unreal v1.28.0, published 2023-07-01.

When i activate it and attempt to restart the engine i get an error:
Plugin ‘CesiumForUnreal’ failed to load because module ‘CesiumRuntime’ could not be loaded. There may be an operating system error or the module may not be properly set up.

Anyone have any ideas on how to fix it?

Hi @HungryRobotics,

We no longer support Unreal Engine 4.26. In fact, we dropped support for it a long while ago (December 2022!).

Our last release of Unreal Engine 4.27 was on April 2023, version 1.24.0. All subsequent releases target Unreal Engine 5.0 or newer. If you have to use an earlier version of Unreal Engine, I would check out v1.20.0 for UE 4.26, and v.1.24.0 for UE 4.27. However, we recommend upgrading to Unreal Engine 5.0 or newer to receive the latest updates from Cesium, including new features and bugfixes :slight_smile:
