I have an image that works as the world anchor, once it's found then that's the origin and orientation of the world. I did this by chosing that ImageTarget as the World Center.
Problem is, I don't want Vuforia to keep tracking it so it doesn't slightly reposition the world whenever it loses and regains track of the object.
The responses I found tell me to just disable the ImageTarget gameobject. That doesn't seem to do anything tho, since the world still moves and rotates with the tracked image even after I disabled the ImageTarget gameobject.
