My bad, the OCIO config is not germane (well, it’s necessary but not sufficient). You’d need to be able to either specify the color encoding in the write node, which one doesn’t seem to be able to do today, or to modify existing chromaticities metadata with a ModifyMetaData node — and there’s no existing chromaticities metadata to modify.
So yeah, Deke’s suggestion is dead on. oiiotool to inject the metadata into the file.

Duiker one that he developed when consulting on ACES for the Academy? That’s fully ACES 1.0.1 compliant; last update was a pull from Kevin Wheatley on 9/30/2015. https://github.com/hpd/OpenColorIO-Configs On Jan 14, 2016, at 5:03 PM, Deke Kincaid <dekekinc...@gmail.com<mailto:dekekinc...@gmail.com>> wrote: Nuke can not read or write the chromaticities metadata from an EXR. Sadly it has been a feature of EXR for over 10 years. You would need to use an external tool like OpenImageIO's oiiotool to inject the data into the file. https://github.com/OpenImageIO/oiio https://github.com/OpenImageIO/oiio/blob/master/src/doc/openimageio.pdf On Thu, Jan 14, 2016 at 4:48 PM, Hugo Léveillé <hu...@fastmail.net<mailto:hu...@fastmail.net>> wrote: Hey guys I had to deal with exr files that were in ACES primaries. My experience with aces is somewhat limited so I just interpreted it as regular linear in-out. For the kind of work we had to do, it was good enough The small thing I noticed is that when playing back the comp in RV, the file looked a bit different. By looking at the metadata, I noticed that Nuke trashed the primaries in the exr render so now rv was interpreting it wrong. I have to ignore the primaries interpretation in rv to have a plate and comp that looked the same in RV. I know I am delivering the same thing that I received, but still, I am curious on how I can make the primaries info go all the way in the metadata of the comp exr. Do I have to switch Nuke in ACES lut mode or is there a way to do it in nuke's default config?
