I found that
PostProcessStage could work with specific 3DTiles via
selected property. But I also found that Cesium3DTileFeature were also dynamic. I get an array of features with callback of
Cesium3DTileset.tileLoad but it didn’t work.
I’m not sure if there is a problem with my idea or the API can’t be used like this.
I would be very grateful if anyone can provide a solution.
