Hi!

Now recently I have been trying to set up a good redshift houdni to nuke pipeline. Rendering with rop works just as expected (I get same image in nuke and in redshift render view), however I coudnt figure out something similar to be used in solaris.

The aim is to render in acescg and then in nuke viewport get a 1 to 1 match to solaris viewport.
Unfortunately that doent happen.

One way that I have figured out and would like to ask if it good or not.

I set up my solaris scene, then go to the little eye icon in right lower part of the viewport, right click on it and enable color correction. Swith it to OpenColoIO instead of Lut and Gamma. Coose display as sRGB and view to ACES 1.0 SDR Video (I have set windows env to point to my Redshift OCIO config). Then I can render that image, setting view to raw in redshift tab in rendersettings lop (I hope that by doing so I render the image without applying sRGB transform in other words in raw ACES, pls teel me if Im wrong). I drop it to nuke, set color management to ocio and have an exact 1 to 1 match to what I saw in solaris.

So the question is: is this a viable way of doing things or am i doing something stupid, like viewing raw ACES and trying to make it look good? I am asking this because of how drastically different the "lut and gamma" and "OpenColorIO" images look.

Any advice would be much appreciated, thanks

That's correct. I'm not familiar with redshift, but yes, disable all color transforms on output to get an acescg image. Nuke display should match Houdini display when using the same display view transform on the same image data. (compare the cop display to nuke, not the solaris view as the solaris view appears to take some shortcuts with dark values still and loses some precision.

Yeah checking in cop is a good idea actually
