OpenColorIO v2 configuration samples


L. E. Segovia
 

Hi all,

I'm working on porting Krita to CY2021 and CY2022. As part of it, I'm trying to reimplement the OpenGL helper classes to use Qt's API, while also preserving compatibility with CY2020 and earlier.

Since imageworks/OpenColorIO-configs and colour-science/OpenColorIO-Configs both seem to be v1-only (judging by the LUT parsing errors), I'd like to ask if there are there any v2-compatible configurations for testing?

Best regards,

amyspark

Hi amyspark,

Yes, the configs you mentioned are v1 configs but they will also work in the v2 library.

There is a v2 demo config that illustrates most of the new features in the OCIO repo at:
OpenColorIO/docs/configurations/ocio-v2_demo.ocio

Also, as was discussed at the OCIO presentation during ASWF Open Source Days, there is an ongoing effort to develop new ACES configs that leverage the new v2 features.

This effort has already produced a v2 ACES reference config that may be used for testing.

There are some gists available for work-in-progress, such as this one:

Hi,

Beyond the Gists, they should be available in the releases from the repo: 

Cheers,

Thank you both for sharing the alternatives!

Upon further review, I found out I'm running into the C locale parsing bug:

https://bugs.kde.org/show_bug.cgi?id=407921

https://github.com/AcademySoftwareFoundation/OpenColorIO/issues/297

I already commented on Doug's proposal in #1322 - so far I'm making do with Natron's thread locale handler.

Best regards,
