Check https://openimagedenoise.github.io/ Intel's way, HW agnostic, fast and from my experience, feels better than NVidia's - which, after a while of using, "revealed" to me in producing kind of a strange, "cellulitis-alike" splotching pattern. Can easily be observed with low sample renders fed into...

in some scenes my computer just crashes with the lates 418.81 and hangs with 418.91, no luck for me then.

Yup, seen few users reporting OCL issues with the latest (418.81) NVidia drivers. Simply roll back to the last working version.

Strangeness with Indigo shows even on high CPU core count...

From what i gathered, other engines (Corona, Arnold, VRay...) don't exhibit such an issue.

yes now works !!! thank you, thak you all.

Great! A perfect way to start jollyful days

That's why demos are available & users are here sharing experience. IMHO, it's nothing to worry about, just don't follow the hype blindly, but get experienced yourself. I got a Maxwell (Q M5000) and a Pascal (GTX 1060) cards so it's a bit trickier to "update drivers" since they don't fully comply, b...

Well, i've been observing "latest NVidia drivers" occasional breaking OCL rendering for more than couple of years already, why i always have a backup drivers ready & i've recently noticed elsewhere that v.417 is again broken...
didn't test it as i don't have to

if you haven't yet, uninstall automatic windows drivers > install NVidia ones (if latest don't work, try with previous versions)

Or simply mimic, recreate reality It's Indigo!

Yes, it can be done via OCL. IMO, denoising is worthless and expensive hack considering spent resources VS return value . Especially, when a feature is locked to specific platform. Also, an argument "beneficial for previews" doesn't hold any substance - previews are previews & PT renders can simply ...

Alembic object renders flat shadet in Cycles while in indigo it renders smooth.
Why is that so?

Are you using Edge modifier to define edge shading? IIRC, Blendigo doesn't read Normals setting from Blender.
Can you post example file to check?

confirming black/broken .exr (either with: "Save Image", "Save Un-tonemapped Image" or "Save Layers & Channels")
Tested with: Irfan (black), GIMP (exr plugin crash), picturenaut (black), blender (black)... (png & exr attached)

If you have NVidia's GPU, here's a standalone build for windows of NVidia AI Denoiser from Declan Russel . NOTE: Works only on unidirectional PT renders. Or in other words, it doesn't do shit to BiDir renders. :wink: Along with 'Beauty' (Image /-i) pass, you can also feed it with Albedo (-a) & Norma...

If out-of-core rendering is possible with OpenCL then we can add it. OpenCL 2.0 adds 'shared virtual memory', which maybe does the trick. Below is a link to posts about Cycles ability to offload textures (VRAM > sys RAM). It's also mentioned that latest AMD drivers give such ability without the nee...

IIRC, newer AMD cards have the ability to use CPU RAM (offloading textures). Saw it work with Cycles.

Really nice.
Thank you.
