Blender 2.81: Open Image Denoise Test


Leroy writes:

Open Image Denoise is a new feature in Blender 2.81, you can download it from daily builds. It's amazing. Thanks Blender developer!. So cycles or eevee, which one would you choose?


    • It seems to me that it useful for giving previews to your client before final render of animation. Is not suitable (like other denoisers) for production renders, but good for previews.

      • Yo, what do you want for nothing right? It it's temporal or not, like you said even if its just to get a client a "quick"'s totally work the cost of admission! =)

      • Hi,
        Altus denoiser is temporally stable but have a cost and need to render two frames with different seed to denoise.
        This one (AI denoise from Blender) can be use in animation but you need more samples to stabilise and avoid artefact and also work better if you have a lot of textures informations cause use it to to keep details. Here a test I done with this denoiser in animation (I used the AI denoiser from E-Cycles, the same but in a group that fixs some issues) :

  1. Oh my god, OpenImageDenoise is literally the coolest denoiser we could have gotten. And look at the irony- released just after Mr Andrew Price spends an hour talking about how Blender is lagging behind in terms of features by not opting to implement an AI-based Denoiser instead :P

    • AI Denoiser is available with "e-Cycles". Sure it´s not for free yet, but if you do many production renderings it saves you tons of time (result is way better than with the built in denoiser, even with lower samples) and is definitely worth the money. If you´re rendering with Cuda based GPUs it speeds up cycles and nearly reduces rendertimes by half. If I got it right, e-cycles will be an official feature of blender soon - and then be free to use.

  2. in this case, sampling settings are not anymore needed ! wooo ! awesome... Rendering will never be like before

  3. Looks great. I'm hoping eventually this becomes a simple checkbox like the current denoiser, rather than being integrated as a compositor note.

    Also, does anyone know if this makes use of the RTX chipset like the Optix denoiser?

    • while i agree i'd be convenient to have it be a render checkbox like the current denoiser, i wouldn't want to lose the compositor node. the "built in" one never worked with baking, whereas the compositor option has already been transformative for being able to clean up my AO bakes!

    • As far as stated in the overview ( Intel OIDN runs on a Intel 64 bit architecture CPU and automatically exploits Intel SSE4, AVX2 and AVX-512 vector extensions if present. A CPU with support for at least SSE4.1 is required.

      So no RTX, but this is better since can be used also with non NVidia video cards.

  4. Unfortunately OIDN still is too aggressive on high sample images. It gets rid of many fine details like bump maps and wanted specular highlights. It's also a bit unpredictable on some edges. Works great on noise in transmission and SSS though. So for now it's best to blend the images from OIDN and Blender Denoiser with masks.

  5. I see on several places some comments that it is not good enough for animations. Don't see it that way.

    What if you use it as preview-render. (For example giving customer or your boss a preview and once they agree go for the high quality render).
    So don't see it as suitable for end-production. I guess none of the denoisers available will be. (when using 50 samples).
