What happened to all the camera transforms and ACEScc? #119

Open NotTheMindProbe opened 1 year ago

NotTheMindProbe commented 1 year ago

I'm using this config as an environment variable, with Blender. I just replaced the OCIO studio config file from last year with the latest studio one, and to my surprise I found a greatly reduced list of camera colour spaces, and no ACEScc. What happened? Is that intentional or the result of an issue on my end?

Are you sure you’re not using the CG config by mistake? We release two configs for users - CG and studio - and what you’re describing sounds like CG.

The CG config in fact contains no camera color spaces, as it is intended for fully computer generated work.

Let us know! :)

This issue existed in studio-config-v2.1.0_aces-v1.3_ocio-v2.3.ocio. I have now tried this with studio-config-v2.0.0_aces-v1.3_ocio-v2.2.ocio and the behaviour is as I wanted. So it seems 2.3 might accidentally be the CG version instead of the studio version, or something with the way it's configured makes it only work with the CG colour spaces.

We’ll take a look! Thanks for checking.

Hi @NotTheMindProbe,

Where did you pull the files from?

The difference is as follows:

@KelSolaar the OCIO config files? From the latest release over here on GitHub. In the assets https://github.com/AcademySoftwareFoundation/OpenColorIO-Config-ACES/releases/tag/v2.0.0

doug-walker commented 3 months ago

Are there any other Blender users that could confirm this behavior? Looking at the configs and trying them in various other apps does not show this issue.
