I understand what you're saying, BUT I can still go into a custom AOV group, and tweak to my hearts desire because it's a POST addition - so in short, an ADDITIONAL LUT channel inside the POST EFFECTS tab would yield additional POST control that is external to all of the OCIO response - correct? That's where I would suggest an additional LUT channel be where custom LUTs can easily be generated from photoshop and applied as a post effect. The same way you would from opening to composite after the fact, just inside octane. Inside the imager would infact be a more non destructive approach - but simply put, you want to open up all shadows, adjust color, anything you'd also see from the magic bullet options, you should still be able to do regardless of the OCIO config with ACES and it just saves with an ACES-sRGB output jpeg/png?
Hi sdimaging,
I am strongly believing that you did not understood my previous message. I will do my best at simply explaining why your request is not viable:
Octane: • Octane (at the moment) does not have "color corrections" tools as available in e.g V-Ray or Corona (the renderer) VFB
https://docs.chaosgroup.com/display/VMAX/Color+Corrections. It might come to Octane in the future and must have been probably requested already.
• Using OCIO Filmic (from Troy Sobotka) provides various "contrast-looks" - I have attached a .gif (I do not know if it will preview on the forum).
OCIO:• OpenColorIO (OCIO) was initially developed (since 2003), open-sourced by Sony Pictures Imageworks and ❝ is an Academy Scientific and Technical Award winning color management solution for creating and displaying consistent images across multiple content creation applications during visual effects and animation production ❞
https://www.elsksa.me/scientia/cgi-offline-rendering/ocio.
• To simplify the understanding, one could think of OCIO as a "plug-in" that "takes over the native built-in color management options" of a given software (including renderers). Again, the wording is technically not appropriate but for the sake of simple explanations...
• What you are describing is already possible but requires the know-how when using OCIO.
• It is possible to use LUTs with OCIO, but it has to be set-up within the OCIO "environment/ecosystem". In order to do so, an understanding of the fundamentals will be necessary
https://www.elsksa.me/scientia/cgi-offline-rendering/cgi-color-management-survival-kit - then, the OCIO documentation would contain information for using custom look-up-tables within an OCIO based color managed pipeline:
https://opencolorio.readthedocs.io/en/latest/index.html however, understanding 1D and 3D look up tables is upmost important.
Unfortunately, Photoshop being far from a professional digital imaging software, the options are limited with it. In such case, and without relying on unofficially supported third-party plug-ins, the solution in your case would likely be to avoid using OCIO packages.
I hope it did clarify some of the questions or confusions you may have had. Please, do not hesitate to let me know if part of it was unclear.
