Google 3DTiles do not cast shadows

Having fun playing with the Google 3DTiles in the world, but I noticed that dynamic shadowing doesn’t seem to work properly with it.

I tried plugin versions 1.25.1 and 1.26 on UE 5.0.3.

The Google 3D Tiles use the glTF “unlit” extension, because they already have lighting baked in. But you can ignore this and rendering them with UE lighting anyway by setting the “Ignore KHR_materials_unlit” property on the Cesium3DTileset.
