The official website tutorial has the following content about " Custom Geometry & Appearances".
Instances are independently accessible after they are combined. Assign an
idto an instance and use it to determine if the instance is picked withScene.pick.
But I find that the pick.id is not the id of the geometry I clicked but the id of other geometries.
For example, I clicked the left geometry but i obtained id of the right geometry in red box.
Why does this happen and how can I get the exact id?
Any feedback would be appreciated!
