I’ve created a little script for 3ds max to facilitate Camera Animation export to Unreal Engine 4 Matinee. Installation: extract the archive to your Root 3ds max directory, it places the required files in the MacroScripts folder. It's very simple, just add the item to your toolbar/quad menu, under 'WeevilTools' When you run it, you can pick your desired camera from the scene, then hit the Create button to prepare a pre-baked clone of the camera ready for export, with the UE4_Baked suffix, ready to export via FBX to matinee.
UPDATE 1.02: I added the ability to select a time range to be baked before export, useful for scenes with multiple cameras that need to be exported independently, it also has the ability to reset the timeiine to the original range once it is done working.
