I have implemented clipping on google photorealistic tiles. The problem is, when I clip an area, and then on mouse hover on 3D model / extruded polygon within clipped area, viewer gets crashed… I dont know why is this happening because with cesium 1.91 everything is working fine.

Hi @saadat2930,

This is a bug. See There is a possibility of throw an error in a frame when continuously modifying the clipping planes and picking · Issue #11410 · CesiumGS/cesium · GitHub for more info.

Thanks,
Gabby

Hi @Gabby_Getz ,

Thanks, I resolved it by not adding clipping plane collection multiple times in the code, instead I added an empty clippingPlaneCollection at the initialization of 3D tileset, and then I use removeAll() function to clear existing clipping planes from the collection & add new planes to that collection. This way it is not throwing any error.
