We support ACES 1.2 OpenColorIO configuration installed on the farm,

In Maya you have two ways to address it:

1. In the Maya Preferences in Ocio Config Path use : “C:\ocio\aces\config.ocio”
   
   
2. If you want to use another ACES version:
   you can copy your ACES directory in your project directory “sourceimages/” and
   In the Maya Preferences in Ocio Config Path use : “..\sourceimages\aces\config.ocio”
   (Don't forget to use the Maya→File→setproject
   to set the project directory where you have “sourceimages/” and your other assets)
   

Please send a test project first (6 to 10 frames for instance) to the RANCH, to confirm everything goes fine.
Please come back to us at contact@ranchcomputing.com in case of any trouble or questions.
