Adding metadata to an EXR render?

Good morning!
And happy new year!

I’m looking at adding some info from my sequencer to the metadata on an exr render at render time.

I have a BurnIn getting some info from my scene, like camera height and distance to objects. But it seems to only be “for show”, and the info isn’t saved on the exr itself for later use in Nuke or DaVinci (exept burned in the frame as jpg… which isn’t good enough :sweat_smile: ).

So my question is, is there a way to add that info in from the BurnIn blueprint? Or any other way to add it during render? Saving a variable somewhere, then adding it?

Thank you!
