OTOY Forums

I'm trying to learn the free version of Blender Octane, and I'm trying to figure out how to render a multilayer EXR sequence in Rec.2020 ST2084 1000 nit to bring into Resolve and export an HDR video.

I searched the manual (which seems a few years old), and the only instances of HDR I could find were referring to HDR images, not the TV standard. I also searched for 2020 and I had a lot of results because the manual talks about Octane 2020.2, but nothing about Rec.2020.

In the Render tab there is a setting called "Final image render" that has choices of Octane Default, LDR and HDR, which I suspect is also for HDR images, not so much the TV standard. And the Octane Output section, for color space has two choices of ACES and sRGB, that's all. No Rec.2020.

Does this mean that this version of Blender doesn't support and HDR Rec.2020 workflow?

Thanks for your reply. So basically what you're saying is to just render the way Octane recommends, which is to set the color to raw, and then switch to Rec.2020 in compositing, correct?

I'm a bit confused as to how the Rec.2020 HDR pipeline is supposed to work. To clarify, I'm not a professional working in VFX, I'm just learning this stuff on my own, so I don't have the knowledge someone would get from working at even a small VFX house.

So in standard Blender, I see that there are four options as far as the target display device: sRGB, P3, Rec.1886 and Rec.2020. Since Blender can't output a real Rec.2020 preview (at least not on Windows, I still have to try it on my Mac), I work in sRGB, and before rendering, I switch it to Rec.2020, which obviously looks awful because it's not real Rec.2020 even if I set the preview window on my HDR TV set. But when I bring that animation into Resolve inside an HDR project that I monitor via a Decklink card with real HDR, it looks great.

What threw me off a bit is that in the Octane version of Blender, I can't find Rec.2020 anywhere.
