I can't find the way to get noice to denoise a multichannel exr in C4DtoA, the software processes the beauty pass and discards all the other aovs (specular, diffuse, etc.)
I render the exr through noice arnold driver preset and if I open the file in photoshop I can see both the noice layers and my aovs.
If I press the read available aovs button nothing happens, if I write in the light group aovs field the name of the aovs I want to process nothing happen as well.
