As I was trying to figure out why my cursor does not make a gazed-upon object focused, I realized that I had to bring the object closer to the camera.
So, I thought there must be a parameter that sets the effective gaze distance for the standard cursor prefabs of the HoloToolkit, but I cannot seem to find it in any of the scripts attached to the prefab (ObjectCursor & Billboard).
How do I set this effective range? Is it at all the case, or is it just a visual confusion that you cannot easily cast a gaze/focus on objects that are far away from the cam?
