Hi, thanks for the reply. I’m using UE5.3.2 btw and the Cesium plugin through the marketplace.

This is the blueprint graph that I’m currently using to remove both the cartographic polygon as well as the overlay. The delay seems to be necessary as otherwise Unreal crashes. The actor that triggers the “Event Destroyed” is the clipping box that you can see in the video below.

This is resulting in the following behaviour:

The first placed clipping box/rectangle can be removed almost correctly although it seems to exhibit a similar error as @Dmc-1234 is encountering in this thread.

> Hi Kevin The cesium example works fine Simple setup Arch Viz 5.3 template added new level Connected added sunsky, bing maps, OSM buildings, set my coordinates to the beginning of my trench in Melbourne. Added a polygon inverted selection I Fixed the OSM Buildings, I forgot I added a basic wall mat to the OSM Buildings because I didn’t like the reflections I was getting from the original material. So when I added the Polygon it it didnt clip. Is there a way to make my own custom material…

Afterwards, however, the tileset doesn’t reset to its original form again.
