Feature Request for looks

Hi everyone,

we had a bit of a conversation about looks in the UX group yesterday and I wanted to create a feature request so it can be discussed more broadly.

I am trying to find a simple solution for non-OCIO experts like me to load looks in a DCC software. Expert users in many VFX studios combine "Views + Looks" but I would like something simpler, if possible. ;-)

So yesterday someone (I can't remember the name, sorry!) threw the idea of [active_looks]. You could have 50 looks available in the config, but only 5 "active"... exactly like displays and views. I'd be curious to see what people thinks of this feature request. In an OCIO config, it could look like this :

```
active_displays: [Display - sRGB, Display - Rec.1886 / Rec.709 Video, Display - P3-D65, Display - P3-DCI]
active_views: [Output - SDR Video - ACES 1.0, ACES 1.1, Output - HDR Cinema (108 nits & P3 lim) - ACES 1.1, Raw]
active_looks: [Vision, Earthy, Complement, Bipack]
```

The idea would be then to have a dropdown menu in "Viewers" for the active looks, if that makes sense. Here is a mockup to give you an idea :


Blender has kinda done something similar :

I know that Nuke and Katana have come up with "OCIOLookTransform" nodes as well but I guess in the viewer it would be more convenient.


A mockup in a render engine would be like this for example :

Thanks,
Chris

Die Anfrage nennt keine Dateien, Tests oder Einstiegspunkte. Beginne damit zu prüfen, wie active_displays und active_views in Viewers dargestellt und bereitgestellt werden, und ermittle anschließend, wie die vorgeschlagene active_looks-Konfiguration und das Dropdown eingefügt werden sollten; als abgeschlossen gilt die Aufgabe, wenn eine abgestimmte Konfigurationssyntax und ein abgestimmtes Viewer-Verhalten vorliegen.
