Getting the tag of an object with Gaze/Raycast

Not sure if this is just a Unity specific issue I need help with or a Hololens issue. Basically , I can't find a way to check the tag of an object with my Gaze/Raycast. Here's some logic -

        Vector3 headPosition = Camera.main.transform.position;
        Vector3 gazeDirection = Camera.main.transform.forward;

        RaycastHit hitInfo;

if(Physics.Raycast(headPosition, gazeDirection, out hitInfo, 30.0f,
spatialMappingManager.LayerMask))
{
if (hitInfo.collider.gameObject.tag == "Interactable")
{
MenuHolder.gameObject.SetActive(true);
MenuHolder.position = hitInfo.point;
}
}

For some reason it does not compare the tag and the if statement is never executed. I got rid of the if statement, and the logic is executed. I made sure my object is tagged Interactable but it still doesn't work for some reason. I may be asking in the wrong forum since this could just be Unity related. Is there any other way for me get object info from a Raycast? Before I was using a trigger zone where the cursor was and I would put a Rigidbody on the object I wanted to get info from, but the world anchor component doesn't like it when an object has a Rigidbody. Pretty stuck on this.

    Try using "Physics.DefaultRaycastLayers" instead of "spatialMappingManager.LayerMask".

  • Just for the records: The physical layer of the raycast has to match the physical layer of the game object. Otherwise the game object is ignored by the raycast.
