    OK so I have two cameras in my game and I have run into a situation where I need to move an object from the view of one camera to the other without the playing knowing that happened. So I need to find a way to match the position of an object so it appears the same on the second camera as it did on the first.

    Any ideas? Thanks

    One way would be like this:

    http://docs.unity3d.com/ScriptReference/Camera.html

    You can basically use WorldToScreenPoint to find where the object is in the screenspace then convert using other camera ScreenToWorldPoint to get world space point of second cameras screen space.

    I was hoping there would be some vector math magic that could do this. I tried this method and its close but definitely not exact. Thanks though.

    If there are differences in two cameras like view frustum there can be differences if one of your cameras is very wide and other is very narrow you of course can get object appearing on first one in corner centered in second one.
