Cant delete OSM buildings area with CesiumCartographicPolygon

When i add a “CesiumCartographicPolygon” to the scene then add a “CesiumPolygonRasterOverlay” component to the “Cesium World Terrain” it deletes the spline area no problem, but when i add the “CesiumPolygonRasterOverlay” component to the OSM Buildings actor it does not delete the OSM buildings in the spline area. what am i doint wrong?

Hi @Yuval_Dorfman,

Your settings look correct, so I’m not sure what the problem is from a glance. As a sanity check, can you click “Refresh Tileset” on Cesium OSM Buildings to make sure that the overlay is actually applied?

We actually have a sample level in the Cesium for Unreal Samples that clips a part out of Cesium OSM Buildings. It’s the level called 08_CesiumClipping. Maybe it’s worth comparing the setup to your project in case something is different or missing?

your sanity is fine, i clicked refresh Tileset 10 times, didn’t help.
I checked out the sample project and I’m doing everything exactly the same.
