Hey I am having a similar problem with my batchrender. This script could really come in handy but whenever I try and run it I am also having an error. If someone could help out I would be very grateful. the error is ( // Error: renderWindowEditor: Object 'renderView' not found) I am trying to render in Mental Ray out of a camera I have set up. anyone know what is causing that error? maybe I am just filling in something in the first 4 lines incorrectly ...
