Notes

Old OCIO V1 website

Multi-platform Python wheels

  • Zach PR to fix linux ARM wheels, noticed it was happening on OIIO

  • Switching to ARM native runners seems to fix things

  • Should we be testing linux ARM in the normal CI?

    • Probably, just for completeness

  • On MAC, we’re making separate x86 & ARM wheels instead of universal, can cause limitations specifically with PIP - Autodesk found a workaround, but is anyone else experiencing this?

  • Remi - we should be able to control the versions, can’t quite remember why we switched.

  • Building universal in addition to specific won’t solve, as you can’t force it to download universal

Color Interop Forum update

Proposed: EXR Color metadata revamp / standardization

ACES 2 Optimization Update

  • Kevin has almost finished getting his work to a stable, matching state between CPU & GPU to be able to create a PR

  • Then the question becomes do we use Remi’s texture lookup fix for metal or for everything or not at all?

ACES 2 Configs

  • Small issue with views assigned to the displays

  • Also in a bit of a random order, is that because of the spreadsheet order?

  • https://github.com/AcademySoftwareFoundation/OpenColorIO-Config-ACES/pull/130

    • Can grab the configs from the top of the PR, links are current

  • Let’s aim for having the configs ready by next TSC meeting

  • In apps not using hierarchical menus, color space order is a bit random - if people have opinions on this, lets us know. Mostly driven by spreadsheet order. Blender is an example of this if folks want to test.
