Exception in using GeoJSONLayer to add layers and maxScale when turning on "ground: 'world elevation'" in SceneView

When turning on "ground:'world elevation '" in SceneView, use GeoJSONLayer to add layers and use maxScale. When you tilt or rotate the map, the layers will suddenly appear. Here is my demo code

Normal scaling:

After tilting:

how to solve the problem

Hi @HHAO, thanks for posting your issue here. If I understand correct, after you zoom in to the map, until the geoJSONLayer features disappear due to the maxScale, if you tilt/rotate the map, the geoJSONLayer features (some, anyway) reappear. Is that correct?

Hi @HHAO, good news and bad news. The bad news is that this is by design. For 3D SceneViews, the scale is based on the center of the view. So when the view is tilted/rotated, the view's scale can interact with the layer's scale, and you can see the effects in your repro case. The good news is that you're not doing anything wrong. Hope this helps!
