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.

enter image description here

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! $\endgroup$ – Animatoring May 28 '16 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. $\endgroup$ – Animatoring May 28 '16 at 3:10
