are there plans to support EXR 2..?

[vlado]

We've been on the OpenEXR 2.0 beta for a while now, and we have a working implementation in the V-Ray stereo helper; however it's not available in any build yet.

great to hear...!
any deep data plans or do we have to use the nuke plugin for .vrimg files..?

[instinct]

The nuke plugin is for vrst files no? And adding to the stereoscopic helper seems to imply it will support deep in the future to come

[oglu]

Hi Vlado,

I'm currently writing my bachelor thesis at Celluloid VFX about a deep compositing pipeline with Vray.
I'm planning to do performance tests, comparing different file formats, complexity of scenes and different compression methods. As i think, that the performance will be the main issue with deep files for the moment.
You said, that you had a working implementation of exr 2.0, when do you think could we expect a working build, to try out?
Also I wanted to ask you, if you are using any kind of compression yet and if you do which one is it? Do you plan to implement different compression methods? I think depending on the scenes and their complexity, this could make sense.

Best Regards
Patrick

A lot has changed in the .vrst files recently in terms of performance; yes we do have compression; we also have a converter from .vrst to OpenEXR 2. Please email me to vlado@chaosgroup.com for more information.

Best regards,
Vlado

vlado when do you think you could implement exr 2? i hope you did plan to do it? it officially out

April 9, 2013 - Industrial Light & Magic (ILM) and Weta Digital announce the release of OpenEXR 2.0, the major version update of the open source high dynamic range file format first introduced by ILM and maintained and expanded by a number of key industry leaders including Weta Digital, Pixar Animation Studios, Autodesk and others.

We switched all nightly builds to OpenEXR 2 months and months ago.

Recent nightly builds also allow you to directly write deep OpenEXR 2 images from the V-Ray "raw image output".

crap i didnt know that, thx for info

cheers

p.s.

could u just plz, tell me where is the option "raw image output"?

[vlado]

In Maya, this is just the regular image output. If you scroll down the list, you will see "vrst" and "exr (deep)" as possible output file formats.

You need the latest nightly from today though.

Best regards,
Vlado

Where does one find these nightly builds?

[joconnell]

Mostly they come at night. mostly...

(sorry not helpful)

Send an email to vray@chaosgroup.com and request details for the nightlies - the thing is that they could have other quirks in the builds hence why they're not put out as full releases. I'd be cautious of them for full production / render farm updates!
