Modify OVRPointerVisualizer to only be visible when colliding with selectable objects

I don't really understand how OVRInputModule is handling the raycasts, but I just want the pointer to appear when I'm pointing at what I want to interact with.



I feel like I should be able to do something like the following, but I'm not getting anything happening. I'm sure what I should be exactly searching for in , but it seems like something that should be more commonplace.

 void Update() {
            activeController = OVRInputHelpers.GetControllerForButton( OVRInput.Button.PrimaryIndexTrigger, activeController);
            Ray selectionRay = OVRInputHelpers.GetSelectionRay( activeController, trackingSpace);

            RaycastHit hit; 
            if (Physics.Raycast(selectionRay, out hit))
            {
                print("hit");
            }

            //if(selectionRay)
            SetPointerVisibility();
            SetPointer(selectionRay);
        }

    So i haven't looked at it in detail yet but i can give you two hints without doing so:

    if(selectionRay) //this will always return true, since you set the Ray before
    i know you commented it out, but i guess you either want to check for if(selectionHit != null)
    or better
    move the SetVisibility stuff into the brackets of the raycast check:
    if (Physics.Raycast(selectionRay, out hit))
    {
        SetPointerVisibility();//does that take a bool? if so set it to true
        SetPointer(selectionRay);
        
        #if UNITY_EDITOR
           print("hit");//it's good use debug logs with     #if UNITY_EDITOR
            #endif
    }
    Maybe you want to check the RascastHit, before setting anything or use a layerMask.
    I think actually, you might profit from just making your own visualization bit that you have a 100% control over and that fits your game's aesthetics.

    I don't know about your experience so if i say obvious things you did different for reasons i can't see, i apologize.

    hope you got something out of it

    Obviously I was in mid exploration of getting it to work.  I finally got something close to I want doing this instead.
    void Update() {
                activeController = OVRInputHelpers.GetControllerForButton( OVRInput.Button.PrimaryIndexTrigger, activeController);
                Ray selectionRay = OVRInputHelpers.GetSelectionRay( activeController, trackingSpace);

                RaycastHit hit;
                //print("hit");

                if (Physics.Raycast(selectionRay, out hit, 500f, mask ))
                {
                    if(hit.collider != null)
                    {
                        print("hit " + hit.collider.name);
                        linePointer.enabled = true;
                        gazePointer.gameObject.SetActive(true);
                        //SetPointer(selectionRay, hit);
                    }
                } else
                {
                    linePointer.enabled = false;
                    gazePointer.gameObject.SetActive(false);
                }


                //if(selectionRay)
                //SetPointerVisibility();
                //SetPointer(selectionRay);
                SetPointer(selectionRay, hit);
            }
