Automatically render entire sequence for each camera in scene?

Not sure. It worked for me. Here’s a screenshot of my very simple setup, maybe you can spot something you’re doing differently. I have 3 cameras in my sequence. They are possessable cameras (meaning they are cameras in the map that Sequencer possesses, as opposed to spawnable cameras which are spawned by Sequencer). I also tried using spawnable cameras and they worked as well.

At first, it didn’t work but then it gave me the warning that I needed to do was to also add {camera_name} to the File Name Format so that it could distinguish the cameras in the written files.

And then a screenshot of the files that it wrote out (you should be able to make out that there’s 3 different cameras)
