Tileset 3d Cut and display only the desired area

Cesium for Unreal
1

hi

I have a 3dtileset(raster, dem) which covers a large area, is there a way that I give a bounding area and Cesium will only show the 3dtiles inside that area?

You can use Cartographic Polygons:

I read an article about Cartographic Polygons. But I need the outside of the polygon not to be rendered, is that possible with Cartographic Polygons?

Yes. Just toggle the Invert Selection property on the CesiumPolygonRasterOverlay.

Hello. Desiring to create a bounding area like the original post I have followed the steps in the ‘Clipping Tilesets’ tutorial (Twice) and selected the ‘Invert Selection’ box and also refreshed the tileset and nothing is being clipped. Where might I look to ascertain my problem? Thanks!

I added a CesiumPolygonRasterOverlay to the Cesium3DTileset actor and then added a polygon array, so it was cut and displayed normally.

Thank you. That was the issue. When I added the CesiumPolygonRasterOverlay I did not have the Tileset actor selected. It all works now.
