It says that, but I can't get Iray to chuck out the right AOVs - I've tried rendering out canvases, but Iray doesn't have an albedo canvas option (while "Diffuse" is sometimes an interchangeable term, the results that particular canvas gives are definitely not suitable for what the denoiser wants, and the results of trying to use it are correspondingly worse than just running it on the "beauty" render).
I want to use this but I must be dense do you apply this during the rendering process or after? Sometimes I just scan things instead of really reading something. It's something my wife has reminded me often.
After the render, outside of DS.
Copy that thanks!
Spot on!
NVidia has been known to produce some terrible clunkers—drivers that don't work as well as ealier versions, or have compatibility problems, or both—so I've been reluctant to update mine. But, after creating a restore point just in case, I bit the bullet & installed the latest.
Now both denoisers work fine, taking about the same time—a couple of seconds for a 1920 X 1080 render—to produce approximately the same results. So far, I can't see much difference in performance or output, but further comparison is obviously in order. Your DnD utility makes it super easy to switch from one to the other until I can decide which I prefer.
So thanks again, eh? (as we're alleged to say in Canada)
You're welcome! In the next version you will be able to switch between them with just a click, and have other options as well. The current one will expire on march 30, I will post links here to the next update before then.
In the DS 4.11 beta you can also enable it so it works during rendering (under Filtering).
You're doing a great job, thanks!
Do you mean the postdenoiser stuff? Or am I missing something?
Too bad I have an AMD CPU, if the Intel one is really better!
Thanks, but all I'm really doing is creating a DnD interface for the standalone denoisers. The important stuff is made by others. :)
The nVidia Denoiser is built into DS 4.11 and doesn't need any 3rd party apps or add-ons to use. It can be enabled under Filtering in Iray settings. The effect is the same AFAIK.
Your CPU should work as long as it supports SSE4.1. The easiest is probably just to try.
I'm going to add support for Albedo/Normal AOVs in the DnD App, do anyone know what file extensions are being used for these?
Thank you for the DnD version!!! Love it!
I am too greedy for asking this, but is it possible to support Tif files please? :D
Sure, if the Denoiser supports it. Doesn't look like the nVidia version does though, but maybe the Intel version does. Can't test it unfortunately as my CPU doesn't support the Intel version.
Thanks! That would be awesome!
The Nvidia one supports tif. I´ve been using it with my tif renders :D
Hm, you're right. I tried yesterday but the denoiser ignored the tif so I concluded it wasn't supported. But now I've tried again and this time it worked. Must have done something wrong. :)
It also supports bmp I can see so I'll include that also.
Both command line denoisers are built upon Open Image IO so you should also allow PSD, OpenEXR and HDR
The EXR format could be usefull in order to use Iray canvas
It seems Iray doesn't have albedo canvas. I don't know if that works well with diffuse Canvas
NB : just had a quick look and OIIO even has support for ffmpeg so it can perhaps also denoise movie clips
Thanks for the DnD, Taoz! I've been using it. So easy and fast!
Unfortunately, having tried with both denoisers, it does not, and actually makes the results worse.
It isn't, for DS, necesary to handle this as a separate script - you could run the denoiser of choise using http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/rendering/render_post_process/start as a framework and DzProcess to handle launching the denoiser.
That is interesting, thanks for pointin it out!. Love to try this, cough, ahem, if someone makes a script based on that example! (especially if the script creates a new denoised file, in the same location as the original render, so we can see what we prefer)
(...and yes, I did try, but I could not get ShowURL to work with arguments, and dzProcess is beyond my skills...c'mon code-jockeys!!!)
I've added these, though the nVidia denoiser didn't work with a random psd, it couldn't save the output file (see screenshot). Can't test the Intel version as my CPU doesn't support it.
exr and hdr worked OK though the exr increased a lot in size, from 547 to 944 KB
You're welcome!
I did a quick test and indeed the denoisers can open PSD files and save to an other format but not write them. And a quick look to OIIO sources shows no PSDOutput.cpp and just a PSDInput.cpp, unlike for the other format. I don't know if it's a licencing issue or something else but with current release of OIIO I guess you can't write PSD.
The OIIO support for denoisers is pretty much basic and are just used to open and close files. I guess all format options use default value, as you can't specify compression option, etc...
I'll try to make a test to see what I can get. The albedo retains all the texture details, so I understand that it is superior to the diffuse canvas for denoising
But something should be doable
OK. Do you know if there is a way to make the denoisers (as they are now, using command line args) save psd output as another format, like png?
ETA: never mind, you just change the extension for the output file to what you want, I can see.
Maybe a silly question but is there a way to fine tune the denoisers or are they all-or-nothing? I'd be happy to put up with a little grain if I could eliminate the bright spots that come with glossy surfaces. Or perhaps there's another parameter in the IRay Render Settings I could tweak?
There is a blend parameter to control a mix amount between denoised and original pic but I think you're better off doing that in an image editor as you'll be able to see what you're getting and thus fine tuning the proportion
A bit of a stab in the dark but I tried a parameter in the Render Settings called Nominal Luminance. I set it to 50 and that seems to clear the bright spots somewhat better than leaving it at 0. No idea why that should work but I assumed that it had something to do with the fireflies setting immediately above it.
Oh no, when I open the DnD For Nvidia Denoiser it tells me "Version Expired"...why did expire? xD
And where can I find the newer version?
Hopefully Taoz has an update coming
Sorry, I accidently set it to expire a day too early. It was just a test version, and I don't want these to float around and cause confusion, so they have an expiration date.
I'm always done with the next version, should have been out yesterday but I had some problems with my programming PC and had to reinstall it so everything got a bit delayed. You can download it here and try it if you want, it should work but hasn't been tested very well:
https://taosoft.dk/software/freeware/dnden/updates/DnD_for_nVidia_%26_Intel_Denoisers_1.000a_NET4.zip
Check one or both denoisers, it can do both at the same time (Intel has not not tested though but should work). If you check the Output Format box it will convert the file(s) to whatever format you choose, if unchecked it will save the files in their original format. Save button will save the selected format as default format.
It will go online when you start it and check for updates, if there is an update it will notify you, otherwise not. There should be an update one of the next days.
Heya Taoz,
I just tested the new copy with the Intel denoiser and it works flawlessly (for me) once again.
Thank you very much for this free handy little tool and the updates. I like the new features!
