as in you have mapped a reference to your camera and the reference is moving? create new cameras and use them for your reference mapping ?
Not too sure what kind of referencing your using and what the issue actually is, what is moving out of place?
I personally use a mapped NURBS plane with transparency on an SDK. Or use camera references and then script them to snap togeather or go further apart depending on what i want to to do.
