@GHebert Did you get this figured out? Do you know if you can do it for camera mapped textures?

I can get the command line renderer to render a specific Take from a file by using the -take flag.

How can I get that one subprocess to render all Takes from a given file? I don't want to have to load, unload, load, unload the commandline renderer for every take.

Something like
... -take Take1, Take2, Take3
