PS - does anyone know what Up-Sampling is supposed to be doing...
It just makes my renders look pixelated/artifacty
Is it supposed to smooth edges, it seems to do the reverse....?

How do you make it work? I don't find where I can see the final Up-Sampling image. If I render 2000x2000 px project, at final it has to be 4000x4000 px. But where is it? I don't see.

Wait, I see -- the rendering speed is increased vastly, but it only makes sense to use with high res output.
So, don't use on a default 540p or what have you, try using on a 1080p or 2160p.

Ramone, there are several pieces-
To turn on use the drop down that has the Sampling Mode - I don't know what Sub-sampling does, but Up-sampling is faster render speed on high resolution.

Then, AI is just an option for whatever mode you are using. It is not the actual "On-Off" as it were. (The "Sampling Mode" drop down is the "On-Off")

What you see in the viewport is what you get, it is not like Denoiser where it has an pass to see Off vs On.

If you put it on 2x2 upscaling it will render with half the resolution in the background and will preview the full res set in the resolution tab.

So of course if you render full hd with 4x4 upscaling it will render 480x270 (in the background) and upscale it to 1920x1080 with the AI and you will see a 1920 x1080 image with a bit pixelated articats. But it is way faster.

Hi guys,
AI up-sampler crashes using Titan X (Maxwell) and Windows 7, not using window 10. Pascal works fine.

Hm. For me, it does not work. Doesn't matter if AI upsampling ON or OFF. The render time is the same and final render quality the same.

Ok, what settings did you select? You have a dropdown menu for 2x2/4x4 up sampling, and an enable checkbox which you have to check.

BIG ISSUE-
saving a 16Bit image with up-sampling crashes Octane 2019 XB2.

(8-bit saves fine)

[Jolbertoquini]

Are you going to improve AI Up-sampler? For now, it is not so perfect. Topas Gigapixel AI makes the job better for now.
And how to view AI Up-samplered image? I do not see any new pass.

Yes, Topaz has a sharpen filter over the top which gives a better feel but also Topaz run on a 8bit tonnemaped image. I think is because octane probably run on the linear render on exr.
Maybe a option to run on tonnemapped images would not give this aliasing issue problem is if you render to be comped on exr you get that.

I mean this is a guess... I don't know the code under the hood.

Awesome begging Octane dev team ! thanks for that.

Cheers,

The vertex displacement auto bump shading don't work in layered specular layer

Noted, we are looking into this.
