Vray denoiser - squares and blotches are ruining my render.

[JD3D_CGI]

I'm tinkering with a de-speckle pass before denoising, but it's not quite where I want it to be yet. It's something that you can try on your own though - if you can take an OpenEXR file and de-speckle it in PhotoShop or something and then pass it back through the V-Ray denoiser, it might work better.

Best regards,

What are you using to despeckle - please bear in mind this is for an animation, and the speckles are in the reflections (with depth of field)... I would need to despeckle all channels yes?

Is there any way you can let me know when this is featured in the nightly builds?

Yup, very good points, will keep them in mind.

I'll try, but it will probably not be in time for your current project :/

Has there been any movement on this, it's been a couple of weeks, I've been away so it would LOVE it if there was some nightly nonsense I could try.

Also, what are you using to despeckle? every later?

[vlado]

I actually do have something, but it's not even in the nightly builds and I'm not sure it will work for you. If you email me to vlado@chaosgroup.com with your 3ds Max version, I can get you a build to experiment with.

Best regards,

Email sent! thanks!

Alternatively, for those interested, i have a nuke node i could share, which removes fireflies and NaNs. (EDIT: Attached)

[JD3D_CGI]

Oh, that's cool very kind of you.

Sadly I'm on After Effects... does your node strip out of all the elements pre-denoising?

[^Lele^]

Not, it just checks pixels with a square kernel, and uses the average to fill in the gaps.
In nuke, where one decides to apply it is irrelevant, so i don't need to deal with REs within the tool (well, not for this.).
Does AE these days have a script node, able to run through all pixels? If so, i may be able to make one for it too.
Notice it only works (well, if i say so myself) with individual fireflies. Splotches may require more applications, and even then may fail (ie. i used a simple simple approach, nothing fancy.).

Just jumping in as I have exactly the same issues if I use the progressive render method. It does not happen in bucket mode at a decent sample rate (default settings work fine) and a default denoiser. That makes the progressive renderer completely useless for animations and even most stills.
