Hi Paul,
The Reset button will remove all changes you applied to an object. (Scale, Position, Rotation)
The Move To Center button will place your object at the Invigorator’s world origin which is located at the center of your floor grid.
It is important to have your objects centered this way when you intend to track a 3D layer as at once when you engage the tracking switch, Invigorator’s center will adapt and stick to the center of your 3D layer. If your object is located far away from the center it may not be visible in your comp window.
[Paul Carlin] "If I'm tracking a 3D layer, why is this even changable?"
Simply because you may have to build an object out of several parts or arrange it in a certain way. So you need to be able to manipulate it inside of the Set-Up window even if you intend to track a 3D layer.
I hope this may help. If you are having a hard time to get it right feel free to send me your project without media and I would be glad to check it for you.
Salut,
Serge
