Peter Stache shares a post about a Multiple Camera Render Script that he created that that sets up cameras for multiple camera rendering in Maya. Download the script here.
Peter notes :
“Mayas way of dealing with multiple cameras is pretty stupid, cause you can set the duration of an individual camera (at least not that I know of). I wrote the plugin that creates cameras and puts them into individual render layers. You can then set the start and end frame for the camera and it creates layer overrides in the render settings. The new sequencer in Maya should do that, but you can only preview (playblast) the animation, not actually render it.”
