\*\*Hello all, \*\*

\*\*I have a 3d tile set and a single gltf model. (extruded city and a building model) as you can see in the attachment. I want to hide overlapping part of the 3d tiles . Is there a way to achieve this? \*\*

\*\*Clippingplanes seem the way to go. I tried to use terrain clipping planes example in 3d tiles of NYC, but it is not working. \*\*

3D Tilesets define the clipping planes relative to their center. To get the results your looking for, I would copy the clipping plane collection, and then add a modelMatrix to transform them relative to the tileset:

tileset.clippingPlanes.modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(tileset.boundingSphere.center);

``

Thanks!
