Sun shines through Tiles

I don’t have any direct answers for you, but take a look at this recent thread:

Shadows from geometry hidden by CesiumCartographicPolygon effecting our own meshes

Hi! I am working on a scene for a client and are using Cesium for the surrounding area of a architectural model in Unreal. Our goal is to integrate our own model into Cesium, we are using the CesiumCartographicPolygon component to hide/cut out part of the mesh overlaying our own model. But as evident from the images attached, a smearing shadow is cast on our own mesh from Cesium, this goes away as soon as we hide the Cesium tiles. Part of the Cesium mesh is also suddenly coming into view even …

There are some observations of UE’s lighting system in there that could be highly relevant.
