Why can't my object be selected?

By inheriing from those interfaces, I just create a new tool.Here is the main idea :
Interact with UI elements, then load a new model from disk.
Finally, the model was successfully imported, but I found this new loaded model cannot be selected by controller. And the ray just pass through it!

I tried to select this model(A) in the Hierarchy, then duplicate this model(B), and then B can normally be selected by my controller.
How can I solve this problem?

 

Solved.

 

Please, don't do this. Explain how you solved the problem.

 

I've been through this.
The solution is to use the IUsesSpatialHash interface.

This is a simple code for testing.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor.Experimental.EditorVR;
5. using UnityEditor;
6.  
7. public class cubeSet : MonoBehaviour, ITool, IUsesSpatialHash
8. {
9. #pragma warning disable 649
10.     [SerializeField]
11.     GameObject Cube;
12. #pragma warning restore 649
13.  
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         var cube = Instantiate(Cube, Cube.transform.position, Cube.transform.rotation) as GameObject;
19.         Undo.RegisterCreatedObjectUndo(cube, "Create Cube");
20.         this.AddToSpatialHash(cube);
21.     }
