Aces not loading config

[21:08:09.465] Error : Error: Loading the OCIO profile ‘C:\Program Files\Blender Foundation\Blender 5.1\5.1\datafiles\colormanagement\config.ocio’ failed. This .ocio config ‘C:\Program Files\Blender Foundation\Blender 5.1\5.1\datafiles\colormanagement\config.ocio’ is version 2.5. This version of the OpenColorIO library (2.4.2) is not able to load that config version.

The minor version 5 is not supported for major version 2. Maximum minor version is 4.

This was done in the VFB. I clicked on OCIO to work in aces.

There is also a choice to choose aces in the color management tab in blender. Should I do it through there? But I did not see any difference in the viewport rendering of blender.

And VFB as you can see I could not test it.

Get Blender config from older versions or try this one (slightly modified Blender 5.0 config, OCIO v2.4):

OpenDRT for Blender 5 - General Forums / Blender and CG Discussions - Blender Artists Community

If everything goes to plan, we will release a fix for this next week. I don’t think full OCIO support will make it into this release, as I had promised in an older topic, but the next release of V-Ray for Blender will support the Blender 5.1 OCIO config inside the VFB.
