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

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: diff --git a/studio-config-v2.0.0_aces-v1.3_ocio-v2.1.ocio b/studio-config-v2.1.0_aces-v1.3_ocio-v2.3.ocio

@KelSolaar the OCIO config files? From the latest release over here on GitHub. In the assets |
|
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. |

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?
