Hi Persephone, camera match utility cannot match Imagemodeler for photomodeling, but it can compliment it. Example - if you have calibrated a project and created the spline cage in 3ds Max, you can use another image that is NOT used in ImageModeler in camera match utility. Let's say that your ImageModeler project does not have a top view, you can use a top image of a different resolution using camera match. Hope I am clear. Just a side note camera match is not very precise and can only be used for validation of your spline cage.
I wonder if perspectivematch gives good results. I tried fspy and blender which is similar but it definetly requires a lot further calibration.
