Blender EXR OIIO Transcode

Hey,

edit: working with Blender AgX, not the global OCIO I use for Houdini and Nuke. I got it from the blender folder in the install.

I am trying to make blender EXR renders to go through the OIIO transcode but somehow no matter what I do it gets skipped.

From the deadline logs it looks like AYON isn’t seeing any color space data, so it skips the transcode:

DEBUG:pyblish.ExtractOIIOTranscode:Representation 'exr' has no colorspace data. Skipped.

WARNING:pyblish.ExtractColorspaceData:Host's colorspace management is disabled.

When checking the metadata.json we can see :

"colorspace": null

I have read different threads about other blender render issues, in particular the one mentioned the default EXR data with the empty aov.

Or

or

I kind of feel like this is only annoying me as I can’t find anyone else complaining about it.
Am I doing something wrong?

Thanks in advance for your tips!
