Is it possible to export an image sequence (in this case a sequence of .exrs) from cycles?
For example, I have multiple sets of .exrs for different passes I want to combine into one set of .exr image sequences.

To save all the passes for each frame into a multilayer OpenEXR:
Add an Input>Image Sequence node and use that to import the OpenEXR sequence
Add an Output>File Output Node and set it to Use OpenEXR multilayer and plug the outputs of the Image sequence to it.
You still need a valid output for the render. So create a dummy file, a jpeg file will do. You can erase those later.
Then just set your frame range and render as animation (ctrl F12)
(and remember to erase the jpeg dummy files)

$\begingroup$ I set up my node layout similar to your setup but I'm having trouble rendering out a series of .exr files at the end with all of the passes within each .exr in the series. (Link to setup: i.imgur.com/uQtVKAV.png) When I render one frame everything works great, you get one .exr with several passes. When you try to render out the sequence you get .exrs with a combined pass and one other random pass. Did I set something up wrong? Thanks for the help! $\endgroup$ Commented May 28, 2016 at 3:05

$\begingroup$ Preview of what's inside the .exr files: i.imgur.com/s2rMSwJ.png The first image is the first frame when rendered separately. The second is when it is rendered as an animation. $\endgroup$ Commented May 28, 2016 at 3:10
