The issue of merging geometryinstances, rendering GroundPrimitive, and picking up attribute information in click events is confusing, which has existed for a long time. The current solution is to render GroundPrimitive individually, which results in poor performance. If it cannot be fixed, it should be pointed out in the document to avoid discovering the problem halfway through the project. I hope the official team can fix the bug as soon as possible.

After clicking to pick, the current geometric ID will be displayed, and clicking from any perspective will cause confusion.
