There’s a free D-Noise add-on from Remington Graphics, for the free Blender. While I’m loath to recommend Blender to anyone, this is a top-class state-of-the art GPU de-noiser judging by the tests.
And the Web page blurb for this plugin also states that…
“D-NOISE can run on any image loaded into the [Blender] Image Editor including texture bakes and even photos!”
Thus it seems that, once you work out where the the Image Editor is in the infernal Blender interface, you could then use Blender to denoise iRay and Superfly renders made with Poser and DAZ. It may be worth a try if you’re not satisfied with what you’re getting by removing the fireflies and speckles via other methods. It’s all free, bar your time. I figure that it might cost someone new to Blender about three hours of work to get it all installed, set up and the focussed de-noising workflow pinned down for use with iRay and Superfly renders. If you have a go, please comment on this post and let me know how it went for you. I don’t have the required NVIDIA GPU, so I can’t run it.
If experience with A.I. GigaPixel has made you think that anything “A.I.” takes days to run, fear not. It runs quick, like ‘five seconds quick’ according to Remington, but only with an NVIDIA GPU. It thus requires a… “NVIDIA GTX 600 Series or newer”, which means a card from 2012 or later.
It’s also interesting because it’s geared to 3D render noise, whereas most de-noiser software appears to be more focussed on the mass-market camera market and camera sensor-noise.
There’s a handy new 20 minute tutorial on how to use it.
