Nuke 6.3 Deep Pixel support?

[Dubbie99]

We are using deep on our current job. It is working really great. I can't wait till we can render straight to exr2 though.
I guess that is Vray 3.0?

If you go to the original link with the deep image files for V-Ray, you will find a converter from .vrst to OpenEXR 2 files. Of course, that's still an extra step...

We are just using nuke to convert at the moment.

Vlado, in order to get the latest version of the deep plugins (to run with the latest nightlies + Nuke 6.3/7.0), do I just re-download the same files I received by email back in March, 2012?

[vlado]

The link is different now (we changed our file server). I emailed you the relevant information.

Best regards,

Perhaps somewhat off-topic, but I'm having difficulties setting the Translate Python Script via Python. This code doesn't give errors but also does not populate the V-Ray specific Render Globals attribute:

import maya.mel as mel
import maya.cmds as cmds
postPython = "python code here..."
cmds.setAttr("vraySettings.postTranslatePython", postPython, type="string")

Any ideas why this may be?

Update on the Translate Python Script... the code above works. It's just that it doesn't update in the GUI immediately...

Hehe, seems like I'm walking in your footsteps here...

Has anyone successfully used a .vrst in conjunction with Bokeh in Nuke?
I'm asking because I can't get pleasing results.

Edit: ...and I'm not at all sure I'm setting it up right.

I did some tests with bokeh, that worked pretty well. What exactly are the problems you're facing?
cheers

OpenEXR 2.0 is officially released since a few minutes....
How about the state of development regarding the deepImage-writer? May we see vray working with OpenEXR2.0 soon? I guess you guys we're already using the dev-builds,right?

cheerio

We switched the nightly builds to Open EXR 2 months ago. In the latest ones, you can also write deep OpenEXR 2 files directly from the V-Ray VFB "raw image output" options - there is no need to use the stereoscopic helper anymore.

Hey guys !

About Bokeh, I also am facing some issues with it:

It feels like bokeh works great only if the Deep file also stores deep_color information
Right now, when i'm bluring my image, bokeh doesn't seem to know what to do with parts of the image behind the blured area/ in the blur, and gives me weird hard edges
(it feels like it simply tries to show the color information behind the blured object and can only find a black cutout).

Maybe i'm doing it wrong, but doesn't vray's deep_exr output deep_color by default ?

BTW, here is how i set bokeh in nuke:
DeepRead -> deep2image -> Bokeh "input"
Same DeepRead as above -> Bokeh "deep" input

Thank you very much !

The deep image still stores only information that is actually computed by the renderer. V-Ray does not normally compute anything further once a ray is blocked by some geometry. To answer your next question, yes we did experiment with continuing the ray forward behind occluders, but Nuke did not handle the resulting deep data well - once the alpha for a pixel reaches 1.0, any further deep data is ignored.

With that said, you could experiment with changing the deep fragment merge mode in the Render Elements section, maybe it could work better.
