Shot luts and different monitor calibrations
Simon Björk
Thanks Blake and Kevin for the explanations, really appreciated. The whole thing with having multiple displays seems really nice and seems to work well in Nuke at least. I guess one problem might be that User A (sRGB monitor) saves his Nuke script and when it's opened by User B (Rec709 monitor) the sRGB view is missing and Nuke will give an annoying error. I see that the old spi configs use the same name for views across displays which would help with this, but it might also be confusing for the user. Maybe there's a way to check for color spaces via a Nuke callback before the error is thrown. Still, wouldn't it be nice to be able to set colorspace with an environment variable? That way I wouldn't need to have register multiple views/displays for a situation like this. - !<View> {name: Grade, colorspace: ${DEFAULT_VIEW}, looks: PreGrade_LUT | nolook}

Why the ACES and Nuke configs only have a single display, mostly for
legacy reasons. There were tools which didn't work well with the situation of having different lists of views for different displays, so the ACES config structured all the views under a single display, Ideally tools would be able to handle this case better. e.g. if you have: Display 1 with views A, B and C Display 2 with views A, C, D When the user selects Display 1 with View B all good, but selecting Display 1 from a drop down which choice should be shown for the view, etc. the ACES config basically combined them to say Display ACES, with views 1A, 1B, 1C, 2A, 2C, 2D It is more in keeping with how OCIO is intended to be used, to use multiple displays to represent different display devices.

Hello Simon,
Displays don’t appear to be doing much work in the nuke-default and ACES configs. The spi-anim config has an example of how Display can be used to partition ones Views by the type of display (projector, sRGB monitor).
Getting back to your question about Looks, I’ve never tried to set the colorspace using an environment variable.
Creating Views for each display calibration using the Display key might be the best approach: displays: Monitor: - !<View> {name: Grade, colorspace: Output - sRGB, looks: PreGrade_LUT | nolook} Projector: - !<View> {name: Grade, colorspace: Output - P3D65, looks: PreGrade_LUT | nolook}
Hope I have not steered you too far off-course.

Or is the recommended way to use Displays for this and then filter out the list based on the ACTIVE_DISPLAYS environment variable?
Related to that, why does the ACES config only have a single display called ACES?
Thanks!

I'm trying to build a config that has a shot lut applied as a look. It all works well with:
