But imagine you’ve got it working and are auto-sending renders to a comic-book page that’s set up in Photoshop. Each render drops into a comic-book panel. But, since there’s a lot to render on each page, the renders are quick and grainy and have ‘fireflies’. This grain will not matter so much, if you’re then filtering them using a non-naff artistic Photoshop filter (Mediachance, Sketchmaster 2018, some G’MIC filters).
But what if you’d just like to denoise a photoreal render? Sure you can filter with an NVIDIA-only denoiser, back in DAZ Studio. But that feature has never worked for me, and I guess my NVIDIA graphics card is just not worthy. Or you could lift the shadows and create a flatter and more comic-book look with the Exposure Value and Shutter Speed sliders in DAZ. Less shadows, less noticeable grain and fireflies.
True, there’s a free mcjDenoise plugin for DAZ which actually uses Intel’s OIDN. But it can only be applied to the stack of recent renders. Thus it can’t work to process the render that’s to be automatically sent to Photoshop via the Bridge.
Ideally there would be a Photoshop plugin that uses the open-source Intel OIDN denoiser. Which has a superb AI model especially trained to clear 3D renders. This plugin would speedily fix all the grain and fireflies, in one click. But, rather surprisingly (given the potential market and the very open licence) no-one has made such a thing. There are only two Windows GUI standalones.
What about other AI-powered denoiser plugins for Photoshop? The Topaz AI Denoise plugins were available for CS6, but… only for 64-bit and they were trained for megapixel night photographers, not 3D renders. There were three or four pre-AI denoiser plugins for 32-bit, but they were expensive and (even if still available) are not ideal now.
Thus the fallback in 2023 would be the free and actively developed G’Mic plugin suite. Its 32-bit .8BF is happy to run as a Photoshop CS6 32-bit plugin. Currently in G’Mic, the 2022 filter Testing | Afre | Denoise appears to be the quickest/best on 3D renders. In fact it’s near-instant, which is very nice. But obviously it’s not as good as OIDN. The results are softer than OIDN, and not all noise is cleared. But it’s better than nothing, and if your comic-book page is destined for digital-only… then it may be good enough.
And don’t forget that .PSD is a portable format, so you can do all the render-catching and layout in CS6, and then load the CC 2018 or higher for postwork and filters.
But the ideal for CS6 would be that someone plugs OIDN into G’Mic in the near future.
