Hi
thanks for this .. this saved me a bit of work figuring our how to the metadata.
Did you find in the meantime a way to update the UI?

Hello Sam,
That’s an interesting post, thanks for sharing!
Did you find out more information since the article was written?

I’m looking for a way to write custom metadatas to my EXR renders, through an expression.
(the ‘.verticalFilmOffset’, ‘.horizontalFilmOffset’ and ‘.preScale’ attributs of the rendering camera)

And I need to do it in script, as the scene if fully built in script.
So I guess that falls right into your case, doesn’t it?

I don’t find much information out there on the subject. I’d be grateful for any help on the subject.

Thanks a lot,
Adrien

Hey Sam.

I do have a solution how the GUI is updated correctely if you are adding attribues:

c= customShapeAttributes.EXRDriverTranslatorUI(‘aiAOVDriver’)
c._setActiveNodeAttr(nodeName)
c.updatedMetadata(nodeName)

Whithout c._setActiveNodeAttr(nodeName) the self.nodeName variable is not set and because of that the GUI update doesn´t work.

Hope you still have a use for that.
