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);
        }
