Writing metadata to vrimg

[Fredrik Averpil]

Is it somehow possible to write meta data into an vrimg file and then have it passed on to an EXR (via vrimg2exr.exe)?

If not, I'd like to put this into the hat of wishes

Standard camera meta-data attributes + compression, dataWindow, displayWindow, screenWindowCenter, screenWindowWidth are automatically written into *.vrimg file and they are automatically passed onto EXR file during the vrimg2exr-conversion.

Hi Svetlozar,

With EXR, I can add custom meta data (via the "extra attributes" textbox), such as the name of the project, the date of render, version of Maya/V-Ray etc.

What I was wondering was if there is any way add custom meta data to .vrimg files. I can't find any information on this over at spot3d.com.

Hello Fredrik Averpil
Unfortunately currently this is not possible - but I will add in into our system.

That would be great, thank you!

Fredrik, is it also possible to write those attributes dynamically to the EXRs? Like the scene name etc.?
EDIT: To make this clear, is it possible to query attributes and values from the maya-scene with MEL and write it to the EXR?

[Fredrik Averpil]

Yes, I'm doing it with Python though:

import maya.cmds as cmds
cmds.setAttr("vraySettings.imgOpt_exr_attributes", "vrayversion=2.2;hello=True;name=Rod Stewart", type="string")

Great, thanks! Could be nice to set this stuff with post-translation python while we submit the job to the farm.
