If storage and optimization is "absolutely not a concern", then all the above isn't much pertinent but on a technical level, valid.
In my case storage - is one of the last concerns as renders (even 32bit exrs) take maybe 10-20% of the overall project disk space.

That's a common misconception ...

OpenEXR at 32-bit is technically unnecessary for outputs other than data AOV.
I'm talking only about still images now. Not video sequences. And yes, I'm using AOVs in post, so I do need 32 bit exr. And the images get printed, so sRGB is not a best choice for me )

Maybe, I'll use Octane compositor ...

Thank you.

I'll try it out with AOVs feature.
It was pretty challenging for me to find a way to achieve color consistency between applications in my workflow (blender octane -> 32bit exr -> after effects -> 8bit -> photoshop) on my monitor, and setting ACES:Rec2020 in OCIO view is essential step ...

I've tested it at my side - it works fine in 29.18, but does not work in 30.0 beta1. So I think there really is a bug in 29.19, that were trasfered to 30.0

Hello, I can not change OCIO views on Blender Octane 29.19
I can change views, but it has on effect in a viewport.
It works as it should in Octane standalone.
Can please somebody check, if you have this issue too?

It worked fine at my side in previous verisons.
Thanks
