Please correct me, if I’m wrong but the current denoiser version doesn’t come near to the multipass performance of the 2017 version. I’ve tested numerous settings.
I’m honestly surprised. Seems like all behaves like only old rgb denoising, even when all passes are enabled to consider.
Was the original, true multipass denoising abandoned?
In the old version we can retain the wall bump details, while smoothing out properly GI noises(vertical curtains). Current denoiser is just way too blurry. When I wanted to retain details, all other surfaces are looking like compressed jpg.
The previous, old one may have been better, but it provided many artifacts and bugs. At least for me.
The current denoiser suits me because nothing unpredictable happens to it. At least for now. 8)
@RwVision are you talking about the V-Ray Denoiser that is within Cinema 4D or the separate Denoise tool that comes with V-Ray? I’m asking because you’ve attached a multipass vrimg file and I assume that we’re talking about the standalone denoiser tool.
So you’re comparing the denoiser between V-Ray 3.7 and V-Ray 5 right? Can you tell me which V-Ray 3.7 you get the standalone denoiser from? I’m asking because oddly enough we’re using the same Denoiser versions for both V-Ray 3.7 and V-Ray 5. Right now I’m comparing the results from the standalone denoiser taken from V-Ray 3.70.05 and V-Ray 5 and get the exact same result from both denoisers using the image you attached.
After extended tests, it’s obvious that current standalone denoiser does not even come close to the older version. Multipass denoising is simply not working.
With the older mp denoiser I can get totally noise-free image,without loosing texture or bump details. No compression effect, everything is in place.
The current version blurs everything out, not even handling properly all the grain - simply unusable.
Not to mention the longer frame save times - which I addressed one year ago and still I don’t see any progress. There was supposed to be a new version, with setup of strength for each pass - no news there either.
Ivan - what was the latest denoiser version which utilized the true multipass, with no GUI? My old build (Nov 2016) still has the over-bright refraction pass issue. Please let me know where I can get it?
We are still looking for the reason for this. The change has happened quite a long time ago and we are looking where the problem is. We will let you know if we have any updates.
Hi Aleksandar,
any news about the issue? if needed I can provide files for both Vray 5 and 3.7, this problem should have high priority because without a good denoiser the only way to get clean renders it to lower the threshold a lot with a large increase in render time.
Need to also bump this up - 3 months and nothing?
I believe that Vray denoiser is the same for all softwares, so I can’t even imagine how anyone is using it - And why no one saw the problem?
true, its not recommended for animation but I did test it on little interior scene and it worked surprisingly well. it does have limitations but I find it much better than VRayDenoiser.
