vDenoise Command Line tool Helper (Maxscript UI)

[^Lele^]

If you leave the denoiser aside for a moment, the workflow is dead simple: you add REs normally to your render, set the file output in the V-Ray VFB (for sequences, writing basename.exr will produce basename.0000.exr and so on automatically), and render away.
The max system complains of sequences rendered without saving files, you can ignore it.

What you'll get will be a layered EXR.

If that's not what you like, and would rather split the REs out, there's a corresponding box just below the Raw file.
They can be used concurrently.

It all works mighty fine with Deadline, and Backburner.
At most, depending on version, you may not get direct output access from the farm monitors, but that's somewhat minor.

Notice that saving from the raw file format also allows you to save deep exrs, and the VRayOptionRE will further allow you to set very fine options for your saved images (lossy compression, sample merging, and so on.)

I'm sorry if i snapped back at you, but the max file output's limitations have been a veritable bane of my working life, and the V-Ray file output saved my life a million times, conversely.
So it felt like you kicked in the teeth a very good friend of mine, right there... :P

Sorry for sounding so certain (writing stuff in short often make you sound like that), I'm not at all, using the vray raw output instead of the one Max provides is completely foreign land to me, and my testing this afternoon left me quite confused.
I just don't know what the pipeline should be then, with the VFB and raw image output with just the render elements I need; where do I choose these if not in the Max RE tab?. There must be some guides or something I never read. And my colleagues all use the RE setup from Max and the "safe file" option in Max, I've so far not encounted any other way.
If you can point to good reference for this vray raw pipeline, I sure would like to check it out.

[^Lele^]

No, the vray VFB has worked for a number of people for a number of years, that i can guarantee you, as user.
It will require adjusting some parts of your pipeline, surely, but it's not as dramatic, or broken, as you make it out to be (I am not sure what you're doing wrong, but since you ask no questions, but rather state truths, i can't really help, can I?).
And there is a reason why V-Ray developed its own file output.
You can complain with Autodesk for any shortcomings in their EXR file writer: we can only help making one better, not rewriting someone else's.

[thn]

That makes it work, at least no un-denoised patches, but gone are the other Vray RE I normally use (VrayZDepth fx.), and if your workflow includes Backburner or Deadline, Vray VFB and the raw vray image output doesn't work. You need to use Max's Save File option as far as I'm concerned. Otherwise you get empty renders, RE's missing and stuff.

Just tested both through Deadline and backburner. No success with Vray VFB.
I need to get those worldPositions and worldNormals in somehow, to cure the partial denoising problem.

[^Lele^]

save from the vray raw file output (VFB section in the render settings.).
Just choose exr as extension, and off you go.

p.s.: you know you're in the right place if the usual EXR options dialog doesn't pop up. Then you're bypassing max, and using V-Ray to write your Exr.

[thn]

But they are not added. In the Vray frame buffer yes, but not in the multilayer EXR.

[^Lele^]

yes, you need nothing but the denoise RE.
all the others will be added for you.
Try that first.

[thn]

No, I've got the noise level RE, got an error message on that one also. That one I was able to add from the list with Vray RE:


The worldPosition and worldNormals are not there. I can see those in the Vray VFB. Maybe there's some basic stuff i'm not aware of?

And you're also likely missing the (somewhat less critical, as you can specify it as you did) noise level RE.
Besides the noise level, the two world-space AoVs should be fairly easy to add from any renderer.

[thn]

Great tool, but I only get parts of the image denoised, as you can see in the picture. Any idea why?






There's a warning about two render elements missing, I can't find those.

yes, with pleasure.
Thank you for sharing your method

Hello Lele,
thank you very much for that great tool.

Do you see a possibility, using your tool, to submit a backburner job ?
So that several computers calculate the denoise task, every slave a separate frame of an animation.

Kind regards
Alex

It is possible to do with maxscript, but you may check my approach as well - http://dabarti.com/vfx/using-v-ray-d...nd-to-scripts/ .

19-06-2016: Updated for 3.40.02 (sp4 hotfix), to include the -frames option to pick a subset of frames to denoise in a sequence, rationalised the interface and added ctrl+click to copy the command line to the Windows clipboard.

Find it as usual in the first post.
