wow! looks promising...i`ll give it a try!

this denoising tool should be embedded in Maxwell V4

[mojo]

looks great!
is there a documentation / tutorial how to use altus denoiser together with maxwellrender ? cant get it to work :-/

i see two plugins for arnold and vray ; where is maxwell plugin ?

[Mihai]

There's a standalone on the downloads page.

Ok, so let's do some tests

Few notes we need to know before we start working with Altus Denoiser:
- you need two final renders with different seeds (i.e. every render needs different -idcpu parameter in Maxwell)
- your files must be saved in 32bit EXR file format
- your files must named xxxxxx_b0.exr and xxxxxx_b1.exr

Here is one scene from Maxwell library Bootles on a window [Scene courtesy of Toni Fresnedo - http://www.tonifresnedo.com ]
Camera resolution: 700x1000

I rendered first render to SL 10 ~ 1m20s with idcpu:100 then second render to SL 10 ~ 1m20s with idcpu:1000 and here is the result:

Altus Denoiser applied to noisy image rendered with Maxwell
Comparison:


Altus Denoiser applied to noisy image rendered with Maxwell
Solo:


Maxwell Render - rendered to SL 10 ~ 1m20s, very noisy
Solo:


Maxwell Render - rendered to SL 17.47 ~ 28m00s, still little bit noisy
Solo:



This was just extreme comparison (personally I would use at least SL 14 for source files), but you can see true power of this great tool.
Denoising process took 24 seconds (system specs below) using only CPU, and 10 seconds only, when GPU mode was enabled (NVidia GeForce Titan X was used).
If you encounter in Altus Denoiser an error No CPU device found! you have to install OpenCL Driver - from Intel site

I really like this tool and if something similar would be integrated into Maxwell... whoa

few other notes:
- rendered on dual Xeon E5-2680V2 with 32GB RAM(40 logical cores)
- Maxwell Render 3.2.1.2 was used on Windows 7 x64
- Altus Denoiser 1.3.00 standalone x64 was used
- default settings were used for Altus Denoiser
- you can drag&drop your files in Altus Denoiser

Nice test, thanks! Yes it seems the glass material needed a bit more than SL 10, and the difference there is probably not due to Altus. So you also rendered a shadow pass and all the other necessary channels?

[seghier]

nice tests
i see the examples in the website but this tool add blur to the images
i asked for plugin ; maybe it better than the standalone application and i hope it can denoise like renderman denoiser ;

[T0M0]

Thanks guys.

@Mihai: nope, only raw beauty passes were used

How does it work on materials with textures? like wood or concrete?
denoiser always work fine on flat surfaces without structure, but once the material has a fine structure/texture that gets blurred away too strong.

that's a very good question...
let me add mine: what if I've used 4 computers to render an image. how can I merge all 4 if altus needs 2 ...?

[T0M0]

I made a quick test with detailed textures, but result was... bad Too much blur.

I tried to adjust filter radius and kc's parameters (blind shots, documentations are very poor) but I couldn't obtain a good output.

@choo-chee: Let two nodes run job as cooperative and same for other two. Then you will have two different outputs for each buffer.

that's on way... however I guess it supports v.3 only so for now I can't test (on v.2)

anyhow I think that for now I'm gonna stick with rendering long times and get de-noising done on 8 bit images after merging ...

exterior images usually render fast enough and no noise reduction is needed. interiors are the problem, and noise reduction can be a bit tricky and must be done with masks etc.

BLUR
for this reason i asked about plugin ; maybe the plugin can read the mxi file and do the same with renderman denoiser !

[stanfordr]

I don't see a lot of documentation for this tool. I haven't been able to successfully run any test. I get a non-descriptive message: "Altus Exited with an Error Please Check your settings"
What do you use for the Albedo, Visibility & Caustic channels?
