Static objects

Hi There,

I am attempting to work out how to keep particular objects static when the scene is launched in Unity. I want to have a terrain which remains locked in place, say in line with a table top, then a car as my virtual object which has been mapped using the Object scanner.

Under ARCamera I have set the World Center to 'specific target' but the only objects which show in the finder is the ObjectTarget. Does the ObjectTarget have a particular setup?

Many thanks

Stephen
