Standalone/Tray publisher exr aces cg to mp4 rec709

Hey guys,
how to set up standalone publisher to use a custom ocio when transcoding exr to mp4? I cant find a way to tell openpype to use oiio to convert from acescg to rec709. Any help will be appreciated :slightly_smiling_face:

This sounds very close to this other topic regarding OCIO conversions (even though it’s not focused at Tray Publisher).

I believe that Extract OIIO and Extract Review also get triggered through Standalone Publisher and thus the same settings are likely involved with setting up what you need.

Have you gone through that topic? If so, where are you still stuck?
