"Cesium Polygon Raster Overlay" not applying when OSM Buildings uses the Procedural Window Material

[CarnageFishy]

I want to apply the Procedural Window Material to the Cesium OSM Buildings with the
Cesium Polygon Raster Overlay,

While the clipping works with the default material of the OSM Buildings, it does not work with the Procedural Window Materials.

Could you please help?

Thanks in advance.

Hi @CarnageFishy, welcome to the community!

The clipping is enabled by a material layer called “Clipping” found on the MI_CesiumThreeOverlaysAndClipping material instance, which is the default one used to render Cesium3DTilesets. You’ll need to add this Clipping material layer to the MI_ProceduralWindowsMetadata material instance.
