With the new Denoiser function, we're finally able to drastically reduce the samples in our scene without having to worry about the noise to much.
I'm rendering my scene with less samples now (500 are okay), and because the renderings take so long, I doesn't composite the rendering directly. Instead, I have an OpenEXR output node set to .png allowing me to export all passes as single files for further compositing, so I'm able to tweak things without having to rerender everything again.
But with Denoiser enabled, my "Image" pass will denoise just fine, but all other passes are simply ignored. That means that most of the other passes (like AO, DiffDir, DiffInd...) are pretty noisy now and doesn't really work in composition well. How do I enable Denoising for all of those passes too? I'm aware of this will take about four to five minutes longer per frame, but that's fine as long as my passes aren't noisy anymore.
Any way to enable denoising for all passes without having to rerender eversthing again and again?
