[QUEST] Freeze with use of lineRenderers

Hi everyone,

I'm beginner on Unity development and oculus quest development.
I would like to try to display different perimeters. Each perimeter is the same that the outer boundary and i apply it rotations.

So, i reuse an oculus script I have modified. And, to display perirmeter, i reuse lineRenderer.
Problem: with more than one lineRenderer, on the oculus Quest, the application freezes!

Do you know why? Is LineRendrer so resource intensive?

Thanks so much for help 

Here the code:

1. public class GuardianBoundaryDisplayCustom : MonoBehaviour
2. {
3.     // Depending on the demo manager only for reorient notifications.
4.     public GuardianBoundaryEnforcer m_enforcer;
5.  
6.     // So that we can easily render the rectangular play area and
7.     // the more exact outer bounds.
8.     public OVRBoundary.BoundaryType m_boundaryType;
9.  
10.     // Something to tell the user their guardian bounds aren't configured.
11.     // This isn't a solution a shipping app would use-- it's just because
12.     // the demo makes no sense without bounds.
13.     public GameObject m_errorDisplay;
14.  
15.     void Start()
16.     {
17.         m_enforcer.TrackingChanged += RefreshDisplay;
18.         RefreshDisplay();
19.     }
20.  
21.     void RefreshDisplay()
22.     {
23.         bool configured = OVRManager.boundary.GetConfigured();
24.         if (configured)
25.         {
26.             LineRenderer lr = GetComponent<LineRenderer>();
27.             lr.positionCount = 0;
28.  
29.             // Note that these points are returned in (the newly reoriented) tracking space.
30.             // So rendering them correctly aligned with your guardian bounds in VR is
31.             // straightforward, and does not require additional transformations as long
32.             // as this is parented to the TrackingSpace node.
33.             Vector3[] boundaryPoints = OVRManager.boundary.GetGeometry(m_boundaryType);
34.             lr.positionCount = boundaryPoints.Length + 1;
35.             Vector3 v;
36.             for (int i = 0; i < boundaryPoints.Length; ++i)
37.             {
38.                 v = boundaryPoints;
39.                 v.y = 0.0f;
40.                 lr.SetPosition(i, v);
41.             }
42.             v = boundaryPoints[0];
43.             v.y = 0.0f;
44.             lr.SetPosition(boundaryPoints.Length, v);
45.             lr.startColor = Color.blue;
46.             lr.endColor = Color.blue;
47.  
48.             LineRenderer lr2 = Instantiate(lr);
49.             lr2.startColor = Color.red;
50.             lr2.endColor = Color.red;
51.             lr2.transform.Rotate(0.0f,180.0f,0.0f, Space.Self);
52.  
53.             LineRenderer lr3 = Instantiate(lr);
54.             lr3.startColor = Color.yellow;
55.             lr3.endColor = Color.yellow;
56.             lr3.transform.Rotate(0.0f, 180.0f, 0.0f, Space.Self);
57.             //TODO utiliser lr3.bounds.center pour décaler le périmètre
58.         }
59.         if (m_errorDisplay)
60.         {
61.             m_errorDisplay.SetActive(!configured);
62.         }
63.     }
64.  
65.     // Update is called once per frame
66.     void Update()
67.     {
68.        
69.     }
70. }
