So I have OSM Buildings in my Cesium Project which I am using as a base to generate procedural windows on. I don’t render the OSM Buildings at all and instead overlay that material on the regular Google Earth tiles. I’m using the Cartographic Polygon Component workflow to remove certain buildings as well because I already have modelled versions of them. However, I’m noticing that Lumen is still using those buildings to do its thing and it’s causing artifacts. I assume this is because the Cartographic Polygon is just masking and not removing the meshes from the scene. Can anyone think of a potential fix? I can’t use “Actor Hidden in Game” because I need the material that’s on these buildings.
Essentially I need to do this (from UE’s documentation):
In cases where you have problem-causing meshes contributing to indirect lighting, they can be removed from Lumen Scene using by using the Level instance’s Details panel to disable one of the following:
For “Software Ray Tracing”, unchecking the box for Affect Distance Field Lighting removes them.
For “Hardware Ray Tracing”, unchecking the box for Visible in Ray Tracing removes them.
However, I can’t find these settings on Cesium’s OSM Buildings…
