I don't suppose you have the import script for 3dsmax still? Download isn't working.
This is a long shot but I wanted to ask, do you happen to know if the FOV values exported here are horizontal fov, or vertical fov?
Normally I just assume fov is horizontal, but some of the values exported, e.g. 26.042 and 36.157 seem a little low, whereas if they where vertical values the horizontal equivalent would be ~ 33 and 46.
Regardless, thanks for making this tool.
EDIT: Found an importer for Blender from a link you posted. No longer need the script. Also discovered it's the focal length. Now I just need to find an easy way to get the camera trigger boxes.
