Folks,
Have seen similar posts, but not exactly the same as I am experiencing. My version 16.2 Allegro has missing check boxes in the Film Control options tab within the Artwork Control Form dialog box. The layers of interest are there, but no check boxes allowing me individually select different layers to create/export gerber files.
I have seen discussions about deleting the pcbenv directory and letting Allegro re-establish, but still get the same issue on the Film Control tab of no check boxes.
