I really love the Open Image Denoiser which offers much better quality in most cases.
To be clear I use only the Houdini plugin but I don't think it's possible to have it in Houdini before anything said below is doable in the standalone.
Is it possible to customize the layers fed to the Open Image Denoiser? It's not a usual thing to do BUT it can be so much more useful to have this in certain situations.
Right now it's hard-coded to use the albedo(which I believe to be something similar to the diffuse filter with refraction in mind), this is good for most cases.
But it's pretty much useless if the object itself has no diffuse, and only constructed with refraction/colorful transmission/subsurface scattering (with or without textures/procedural noises etc) In these cases, it would be awesome if one can control what to feed into the albedo channel of the open image denoiser so one can construct a more visually accurate representation of the raw colour albedo requested by the denoiser, instead of the black *albedo* without textures from other BxDFs etc in considerations
Even better if it's made of a customizable denoising render AOV group network (in which I can use my custom AOV outputs). If there is already such a thing it would be really appreciated to expose it to users.
