Hi, I assume you use the new OCIOv2 config shipping with Nuke 14.

Just before the write node, use a OCIODisplay node and set it to the desired output format.
Then set your write node to “raw data”.

Strangely Foundry did not mention this workaround in their Nuke 14 OCIOv2 video.

It’s more than half a year ago since the new OCIOv2 configs were released. I posted about it on my blog as well in last October and pointed in there to a GitHub link. (https://www.toodee.de/?p=6089)
You can read there (DisplayViewTransforms for output? · Issue #82 · AcademySoftwareFoundation/OpenColorIO-Config-ACES · GitHub) that an adapted write node did not make it into 14.0v1.
We are at 14.0v4 and the issue is still not addressed.

Or maybe there is a hidden knob that I am not aware of? This would be great to know.
Maybe someone from Foundry could give an explanation?
The situation is not really user friendly at the moment.

Of course you can alter the OCIOv2 config, but I think this should be the job of Foundry when they ship the new configs with Nuke.

Best

Thankyou sir, it works!
