I need to use 2 different rasterPolygon: one for creating a region (delating the other part of the 3d tileset that i don’t need) and one to delate a small part of that region so i can set my building project in it. I’ve already tried doing this: Create 2 cartographic polygon, edited the MI_CesiumThreeOverlaysAndClipping adding a new level parameter called “ClipIn” set Level asset= MI_CesiumRasterOverlay; FondiAsset= MLB_CesiumClipping. Then in the detail panel of the 3D tileset i added a cesium polygon rasteroverlay, added an array with the region polygon. Then i did the same things for the building poligon but in MeterialLayerKey wrote “ClipIn”. this doesn’t work, it seems like it works when you move in the building area but as soon as you move away the delated tileset appears and then the file crush
