Hello
I test intel image open denoise and it look better than the denoiser of Maxwell and of course very very fast
denoiser of maxwell don't work i don't know why and it is very slow
here the full steps and the result:
1-Download intel image open denoise : https://openimagedenoise.github.io/downloads.html and extract the folder
2-Render : the full image with two channels : Normal and Reflectance
3-Save every image as EXR32
4-Open the images with Photoshop and save them as PFM
5-create text file with this lines: .\denoise -hdr c.pfm -alb a.pfm -nrm n.pfm -o output.pfm and change the extension to cmd (for example : run.cmd)
In my case i save the render as : c.pfm , normal as n.pfm, reflectance as a.pfm

--------------------
The result:
the Render SL = 5:

For transparent materials Maxwell don't create normal and reflectance channel with refraction and reflection information
i hope they add this option in future

very interesting, a little question: I want to try it, do I need to render with maxwell denoiser or a regular render?
oh, and where do you save the files ? if you can explain a bit more... thanks :)

No you don't need Maxwell denoiser, you need just 3 images : the render, normal channel, reflectance channel.
But sadly Maxwell don't create normal and reflectance with transparency information when transparent materials used.
Put all images in the same folder with intel denoiser (bin folder)

well it works, thanks! I gonna test it with some more renders before verdict... but if it works as good as it looks on first attempts, we need to write a script to automate the process, or some simple gui that asks for the 3 files and runs the denoise process.

The script will be useful and i think it is easy to create it but sadly the actual version of pymaxwell don't have help like the old versions
