Getting the noice.exe to run from the commandline

1. get noice_command_generation at https://github.com/zpelgrims/noice_command_generation

2. Supply you own file path for the following:

filename_input = "\"yourFilePath\\yourFileName_Noice_Input0000.exr\""

ilename_output = "\"yourFilePath\\yourFileName_denoiced.#####.exr\""

arnold_bin_path = "C:\\ProgramData\\Autodesk\\ApplicationPlugins\\MAXtoA"

3. If your using Windows, try modifying the file string thus:

filename_input = "\"Q:\\!resource\\footage\\vr_camera_longer\\vr_camera_longer_Noice_Input0000.exr\""

Adding the escape character \ before other \'s and " 's - easy to do with find/replace. Also, don't use the file string generated by the 3ds MAX built-in denoiser, as it use the forward slash / in the file path. It is Arnolds' lack of attention to details like this and overall unhelpful help that I find annoying. It is impactful on our shop's ability to be productive with their render "solution"

4. The run the module from python. Copy the output.

5. Save it as a batch file (myoutpstring.bat) and run it out of a command shell.

This is how a noob like me figured out how get it working :)

You need to render with "output Denoising AOVs" checked. This creates an .exr (youfilename__Noice_Input####.exr) containing four layers which are used by the denoiser: RGBA, Variance, Normals, Depth. They are also good for compositing in AfterFx with ProEXR plugin (free).

You also need to uncheck "Progressive Render" or .exr network renders fail:

I modified Zeno's script to get it to work for me:

noice-command-generation-v2.zip

Thanks @Michael yes I realized how to make it work. Never again noise.... :)

So I guess if I want to make a batch file to denoise multiple files I have to edit the bat file...

Also check this answer from Mads.

wow man... I never tried because I didn't know know :)

So I guess this is for noise reduction of a render image.

It works only with exr?

If I save my final render in tif?
