How to solve the problem of using GeoJSONLayer3D scenes, when rotating the map, the direction of the photo also changes (where I used the featureReduction attribute)

Below is my partial code:

Thanks for your question! It would help to see a screenshot of the current behavior to better understand what you expect to see instead.

I'm assuming the PictureMarkerSymbol is currently shown as a billboarded icon in the 3D scene, this is the default behavior. You can drape them to the ground by changing the elevation info on your GeoJSON layer to mode: "on-the-ground", as explained here: https://developers.arcgis.com/javascript/latest/api-reference/esri-symbols-IconSymbol3DLayer.html

Here are two CodePens showing the difference:

When I set the featureReduction property, the elevationInfo property will become invalid

I am unable to reproduce what you are describing. Can you provide a running sample (CodePen)?
