2026-03-30 TSC Meeting notes

Roadmap update

• www.opencolorio.org/roadmap

  • Support for new version of SMPTE CLF spec has been implemented in OCIO and merged. Yay!

  • Moved a few items into the “now” column

  • Regarding the ACES LMTs:

    • Shared a config for ACES-1 level contrast for use with ACES 2 transforms on the ACES slack channel, please provide feedback if you have it

    • Also have some work to do on the OCIO side to better support LMTs (naming conventions, etc)

  • Better support for OS-level color management - topic for next WG meeting

Wiki page on 3DGS

• Current software out there for GS fits the data and blends in video space.

• This is limiting from a color management perspective

• Doug put together a wiki page and would appreciate feedback:

  • https://github.com/AcademySoftwareFoundation/OpenColorIO/wiki/Color-Management-of-Gaussian-Splats

• Mark B: top example is the most sensible and desired for sure

• Mark T: definitely interested in this - keep in the loop

CI updates

• Remi - some useful updates for us from the last CI meeting notes

  • VFX 26, we’re missing this currently

  • GH Actions security updates

  • Deprecate VFX 22

  • Doug: some checks on MacOS were failing on finding clang - was able to get it to pass by re-running, but EXR and OIIO changed their workflows to hardcode the path, so we may want to as well

• Dependabot

  • Useful? Not?

  • We should look through these, take the fixes, make a new PR with updates where useful

  • Tough to decide workflow - Carol will check with Cary on how OpenEXR is handling it with CLA, etc

OCIOView + Dev Days FYI

• Send over your bugs/features etc

• Meeting Tuesday at 12pm PT

Open PRs

https://github.com/AcademySoftwareFoundation/OpenColorIO/pulls

• Kevin’s PRs - want to get this in first before clang format

• Tried to be order independent - a couple things might be though

• Zach - can we turn off the clang ordering? No, we should get through “the pain” probably and do it right.

• Want the headers to be self-sufficient

• Kevin’s work is in a good spot - never finished, but this is a good spot to stop for now. Next step would be breaking up larger includes so it’s a lot more work

• Another next step would be looking at our unit tests

• #2268 - Kevin - seems legit, not familiar with the APIs to confirm

• #2272 - Kevin - Remi took a look and couldn’t reproduce, just want a second opinion

ReadTheDocs minimum OS support

• Will stop supporting Ubuntu 20, one line update on the docs deployment - should update to ubuntu 24 and pin it, and then do it again

• Sean will make an issue
