denoser in 3.4 with update function like in Max?

[jasonhuang1115]

Is there an update function/button like the one I saw in demo video for Max where I can load the renders in VFB and update denoised result after dial in Strength and Radius?

If not, I have to set up multiple denosie RE with different settings to compare? Will this add a lot of rendering overhead?

An update button is coming in a patch that we will release in the next few days - we didn't have enough time for the first builds, as we had to get them out as soon as possible.

Best regards,

Thanks Vlado. I will check the nightly to get the update patch.

Will the command line tool denoise.exe coming in the nightly also?
Didn't see it in stable.

Will the command line tool denoise.exe coming in the nightly also?

Yes, it's in the nightlies already.

We're trying the command line tool here. Is it only working on multichannel exr/vrimg with the correct elements added. Or can you get it to detect the render elements as separate files instead based on a file name prefix?
If not, can support for this be added?

Also, it sounds like you can denoise the usual GI/Lighting/Reflect/Spec, etc with the command line tool. Is this working, but just not yet added into the built in vray version for maya?

And as a last question. When I am in maya and choose the 'denoise render elements seperately'-setting, my refractions seemse doubled in intensity in the denoised RGB-element. This might be cause the refraction materials are set to affect all channels, but is this something you can replicate on your end?

Thanks in advance,
Simon

Yes.

No, we don't support this for the moment. We might do it, but it's not a very high priority - there are other things related to the denoiser that need to be worked on first.

We have not added it to the builds yet.

Yes, it's a known issue that we need to figure out.

First of all I just want to add that we've been getting great results with the denoised. Its really impressive! So good job there.

We normaly slice our renders up in different regions, and send them to the render farm. Then merge the different slices back to render elements. Different elements needs different kinds of merging, as not all elements are black outside a region (bumpnormal I think is gray for example).
For this reason, and to get smaller files in Nuke, and only use the render elements we need for that comp-fix, with a from- then plus-operation, is why we dont use multi channels exrs.
Do you have any idea on how we could go about denoising our elements on command line without multichannel?
Or perhaps we can figure out a way to merge the multichannel exrs, and then extract them to seperate elements after being denoised.

Yes, it's a known issue that we need to figure out.

Okay! Thats great to hear.

Thanks,
Simon
