OCIO Config Working Group Meeting Notes

Items in PR #80 - last stretch for RC2
- #2 from Doug's feedback - moving "Rec.709 - Curve" to Utility/ITU from Utility/OCIO. Group agrees, decides to leave ST-2084 where it is for now. Added to spreadsheet.
- #6 from Doug's feedback - Dropping the OCIO family hierarchy. Originally feedback was just for CG, but group decided we should do this for both CG and Studio, and Thomas confirmed in this case would be easy to do. This will prevent common color spaces such as sRGB Texture being too deep in the menu hierarchy to reach easily. Added to spreadsheet.
- #7 from Doug's feedback - Hiding the display colorspaces (making them inactive). Group agrees, especially to limit confusion around views no longer being "traditional" colorspaces. For example, people may incorrectly choose "sRGB - Display" as an output color space, not realizing that it does not include the ACES view transform. Need to help folks realize the distinction and new workflows. Added to spreadsheet.
Role updates:
- Change color_picking role to "sRGB - Texture". Group discussed removing, but it is currently called directly in at least Mari and Substance Painter. Changing from "sRGB - Display" will make it more apparent that it does not include the ACES view transform (which is a change from the 1.2 config).
- Remove default role, confirmed with Foundry this should not impact their products currently.
- Leaving matte_paint and texture_paint for now, as they are currently used in Nuke.
Zach's naming spreadsheet
- https://docs.google.com/spreadsheets/d/1wKZeKsRDILYN_vmJuJIpOBxLHgvv-VLZ5rVxAP4VwjM/edit?usp=sharing
- Group agrees changes in here are small enough that it is not worth switching the colorspace naming to pull from the CLF name attribute for this release. Will make an issue and revisit in future.
- Will remove "SUP v3" that are mistakenly in several CLFs for this release. (But this does not impact the configs.)
Gamma 2.2 Rec.709 Display
- Was a noted piece of feedback from the original collated feedback. Group decided to use ACES supported displays as our guiding line, and therefore not support at this time. Can revisit in future.
RC2 timing
- Goal is in the next 2 days, Thomas will update as necessary. Idea is that RC2 ends up being the final v1 release, cross your fingers and toes!
