Hello, How can I use this new feature “Cesium Cartographic Polygon” in Unreal?

Hi @agallegos , We just tried out this process and noticed that some tiles within the polygon aren’t excluded correctly at close distances including the tiles collisions. Is this a limitation of the tool or is this just a beta tool at the moment? [Capture2] [Capture]

Hi @V2i , This looks like a bug in the interaction of clipping with the water effect. I wrote an issue for it: Clipping does not work correctly in tiles that are partially water opened 12:16AM - 06 Sep 21 UTC (UTC) …

I forgot to mention, though, since you mentioned collisions. The clipping is a purely visual effect. You will stil collide with the hidden parts of the meshes. Tiles that are entirely inside the clipping region will not be loaded at all, so you won’t collide with those. But the partial tiles will st…

Thanks for the help @Kevin_Ring , Just a follow up question. We have been provided photogrammetry dataset from Aerometrex. We tried clipping this data but due to it not being quantized data it is not supported. Is there an estimated timeline where clipping non-quantized data will be released/worked…

There’s a PR in cesium-native that adds really basic support for raster overlays (including clipping) on arbitrary 3D Tiles: Raster Overlays on 3d Tiles CesiumGS:main ← CesiumGS:overlays-on-3dtiles opened 12:37PM - 27 Aug …

Good to know it’s been worked on. We will check out the PR when we can. Thanks for the estimated goal timeline.

We hope to provide support for photogrammetry dataset as soon as possible,thanks!

Can it be applied to Cesium3DTileset? I only found the example applied to Cesium World Terrain

Yes. Cesium World Terrain is represented by a Cesium3DTileset Actor in Unreal Engine.

I got a problem, it looks like it works but when look at “lighting only” the masked area is still there, which seems to be affecting the lighting of the building that I have overlayed [1.PNG] [2.PNG]
