OCIO Config Working Group Meeting Notes

  • Where does linear go in the name:

    • Doug - usually say "linear srgb" and not "srgb linear"

    • Group decides: Linear sRGB. No dashes, linear first.

    • For anything with a CLF, we need to have the modern name

  • Remove roles from alias list?

    • Yes please!

    • Will need to update aliases we want in new column in spreadsheet. Will not pull from Legacy Aliases

    • Make the short name the first in the aliases list?

    • It's a bit brittle, relying on the order of the aliases. Could also argue that the legacy name should also be first, as folks will need to reference that too

    • Thomas: should be a first class citizen - a function that generates a "slugified" name 

    • Group: we should go with what we have for now, and create an issue to deal with this later. Either in OCIO proper or in the config generation, to be decided

  • Update role color space mapping

    • Should we include texture_paint and matte_paint in the roles? No matter what we choose, something will break for someone

    • default role: ACES-2065-1 or sRGB?

    • Doug - in a lot of ways, the default role is superseded by the file rules in OCIOv2

    • We should leave it ACES-2065-1

  • ARRI LogC4: group decided to leave it out for SIGGRAPH release. Will add in a later release.

  • Add pure gamma 2.2 display to ACES configs:

    • It is a built-in. 

    • Defer for now.

  • Review spreadsheet

    • Exclude canonlog3 curve for now, as it will require a LUT for this release, revisit later

    • Moving sRGB texture back to utility

  • Studio config: two versions - LUT-free and with external LUT references

    • Tabling for now - discuss at working group session next week to get group opinion

  • Plan of attack:

    • Michael updating spreadsheet

    • merging all CLF PRs (except ARRI)

    • Thomas will rebase studio branch and generate first look config

    • Iterate!
