How to use ACES in Blender

Building Blender
1

If you want to use ACES with the currently released Blender, you can use it by rewriting the config and specifying the rewritten config in a bat file. However, configs such as ACES1.2 distributed by AMPAS and others differ from Blender’s config naming rules, so they cannot be made to work correctly. To solve these problems, volunteer Blender users are distributing configs that have been rewritten for Blender, but I don’t know which one is correct. One of my wishes is that they would officially support this area. Also, does Blender have plans to change the default color space to ACES like Maya and Houdini in the future? If so, when will it be realized? Until then, if you want to use ACES, you have to use Config. I would like them to officially prepare Config for ACES.

hello, maybe these guides by “Daniel Brylka” to use OpenColorIO (OCIO) could be useful:

Blender 3.5:

updated for Blender 4.1

Anyway in the website menu you can find additional guides and info like:

I think that you can donwload the config file of OCIO for ACES, from the original site of OCIO
But i have onother problem. If you download the OCIO file from their original site and use that inside blender, yes you can use ACES, but all other color space or Luts like Agx Filmic, disappear

ACES is free and opensource, i don’t understand why not integrate inside blender by defualt… The perfect thing have it inside color managment with all other color space of blender. Or share a Config.ocio file the allow this

This is not the right place for this, as it isn’t a support forum, but for the record, use this OCIO configuration:

it includes the most common OCIO configs, including Blender’s Filmic, Khronos Neutral and AgX, and ACES and many more. It is compatible with existing projects so it needs no conversion.

The detail of integrating it in Blender is not as striaghtforward as one might think, to ensure all workflows are working, that you get the maximum benefit from the configuration, and things like that.

It is on the radars to eventually pick it though: https://projects.blender.org/blender/blender/issues/68926
