i tried denoiser with another scene but didn't work :
ERROR: - Error running denoise process: FATAL: Unable to find a usable CPU device (are working OpenCL ICDs installed?)
--------
That's documented

http://support.nextlimit.com/display/maxwell4/Denoiser

"In the case you get an error message when using CPU about OpenCL ICDs, it will probably be solved by installing one of these packages depending on your graphics card:

Nvidia: CUDA toolkit
AMD: AMD toolkit
Intel: Intel toolkit"

How did you finally get the denoised image? Using gpu option?

I noticed I also seem to get this CPU error even though I have GPU selected for NR, but it only happens for the first render (sent from Studio). Subsequent NR work ok.

Btw, if saving the denoised output as .psd I only get an empty .psd file.

Why doesn't the background look good?
The background you can see circles like when images are compressed and the color is darker than the original render

I disabled gpu option and tried many times with the same error
than i activated it and render again
This need more tests for confirmation if it is the problem or not , i used intel tool utility and all drivers are updated

Is there no setting to adjust the strength of the denoising? That is usually present in photoshop filters and similar plugins?
In my first test, denoiser seems to take away all details.

I noticed in general the noise reduction tends to darken highlights a little bit. This is alleviated by rendering the base layer to a higher SL. Btw, that error you are getting does only happen if you choose CPU for denoising. The CPU needs a special library in that case.

Regarding to the GPU features (http://www.maxwellrender.com/cpu_gpu_chart/)
what has highest priority in development now ?

Additive layers are still on the "last place" in the list due their complexity or there was some adjustment in your development roadmap regarding to them ?

With latest Improvement - The GPU engine can tile the render to use less memory footprint. would be possible to support extensions like hair&fur / grass and scatter ?

The list is not ordered by priority. The orange ones are things we are working now, red ones are things we are not working on right now, but will be done after the orange ones.

Here is my quick little test.

I don't know why some of us aren't happy with having de-noiser. Personally I think it's pretty cool little feature. I do have a feel that de-noiser eat's up some of the details, but hey it's a SL9.
And it is a completely different story on any SL above 12.

To me, it works great, especially in enclosed areas (read arc viz), I do agree with Mihai - more controls would be greatly appreciated.

However, let's not forget why we all use Maxwell, there are many reasons, but none of them is a "clean renders". So I found myself rendering with de-noiser and blending it with original (un-processed) result to bring some of that iconic maxwell grain back. Probably can skip this step once extra controls are introduced.

Cheers.

i test denoiser again
the reflectance channel don't show all textures why ? and that give wrong result in the denoised image

It's the exact same wood material applied to all the desk? And pieces have proper UVs?
Maxwell don't render the textures for instances in reflectance channel
this is the problem
