So I looked into this Tom. I was able to get the Google Earth Studio camera exported into After Effects, and then exported the AE Camera via the AE3D_Export script you can find on the web...you have to alter the script in order for MAX to understand it but it does in fact import into MAX.
In this case open the maxscript file AE3D_Export created in a program such as Notepad++. Then do a search and replace for "Camera" (you don't need the quotation marks), replace with basically anything...in the cases I found online, people were changing to MyCamera or Camera_. Next in line 19 or somewhere close to the top, find where it says "freeMyCamera" or "freeCamera_" (whatever you replaced the original "Camera" with) and change this back to "freeCamera."
Run the script in Max and you'll have your camera (rotated funky as it always does from AE to MAX), and your null object, assuming you created a track point from Google Earth Studio.
Group your camera and null, rotate accordingly. You'll notice the overall scale to match real-world scaled/modeled objects is waaaaaaay tiny. I'm still messing with my camera matching but right now the scale of the grouped Camera and Null is at 16 million times its original size. Yes... 16,000,000.
