Hi Thomas.

I'm no expert, but I've been using Blender a bit to generate assets for
compositing in other programs (mainly after effects), and I also had the
need for rendering render layers and/or passes to separate files, as after
effects doesn't play well with the multilayer EXT format.
So far I've been using this method that suits me well for that kind of
In the compositor, you can create a "File Output" node, and in its
properties, you can create as many "inputs" as you like, and assign to
those inputs, Render layers, Render Passes or the output from other nodes,
and when you render out your composition, you'll get your files in the base
path you've set up in your node, and in it's respective inout name folder.
You can render them all with the same settings as your main node, or have
overrides per input, so you don't have to commit to a single format all
I think it might be of help to figure out your pipeline. Hope it helps, if
it sounds confusing, let me know and I'll try to explain better and/or send
you a sample file.
