Test Cesium Plugin for UE45 Preview 2

[jgoffeney]

This documents issues with the Cesium Plugin relased for the UE5 preview here.

Create Project

The first issue encountered is when creating and empty project as Games->Blank without Starter Content it automatically adds a landscape which can not just be deleted.

Solutions ( Closed)

• Use one of the other templates like First Person and delete the extras when the new project opens.

Overexposure

After adding the CesiumSunSky it is too bright for the level. The UE4 solution was to select Extend default luminance range in Auto Exposure settings in the Project Settings but this option is no longer available and the Lumen global illumination system is enabled by default.

Solutions (Open)

• A solution is to lower the Intensity (default 110000 lux) in the CesiumSunSky->DirectionalLight options.
  • 20 lux seems to work okay.
• Project Settings->Default Settings->Auto Exposure->Manual reduces the over exposure but it is not ideal.

Flickering Shadows

With default lighting settings shadows flicking on and off on the terrain.

Solutions (Closed)

• In Project Settings -> Shadows switch from Virtual Shadow Maps to Shadow Maps.
