OCIO color picker

[chocbot]

Hi,

so the most current versions let you specify an OCIO transform for image textures. Though I‘m wondering, what‘s the workflow for getting correct colors from the „color RGB“ node as well as the shader‘s color pickers?

I suppose that you could use the color correction and OCIO configuration available in the color picker itself. I think that it has some limitations, something that hopefully will be improved in H19.0

Thanks, I tried that already and it doesn‘t seam to make any difference to how Octane renders these colors.

Hmm, perhaps I'm not understanding you, but the color picker always sends to the plugin the color in the linear color space, which is used later by Octane and updated to the selected Octane color settings. I mean, a color selected in the picker is always the same in the internal linear color space. What changes is how you see it in the color picker window on the monitor. What you need to do is match the color picker settings with the Octane settings to try to get the most accurate color from your picking.

Thanks,

Thanks for your explanation.
I was thinking though, like in a non-ACES workflow I could specify a RGB color in Photoshop and safe a texture, as well as using the same RGB values in a color picker and getting the same result. I thought it would make sense that in ACES I can also set specific RGB values in a color picker and use the utility-srgb-texture transform to convert it to ACES. Something like this is not possible, right?

Thanks, yeah I know that I didn‘t use the accurate terminolgy but I thought it was sufficient to explain my thoughts.
I didn‘t read through your text yet but am wondering, if your workflow also allows combining footage as well as renders from different renderers as easily as in ACES?
However, I don‘t find ACES particularly hard to use, now that Octane allows specifiying the input color space of textures. I‘m just missing that I can‘t do the same for the color picker, actually.
