General Software Setup

This page explains how to integrate AIO-OCIO config recipes with Autodesk Maya, Foundry Nuke, SideFX Houdini, and other DCC applications.

Pre-made Recipes

The configuration bundle contains four optimized recipes depending on your workflow and software type:

Config File	Target Usage	Workflow Description
`config_CG_ACEScg.ocio`	Maya, Houdini, general 3D	Default CG configuration supporting standard ACEScg rendering space.
`config_COMP_ACEScg.ocio`	Nuke, Fusion, comp software	Optimized for compositing workflows using ACEScg.
`config_CG_Lin709.ocio`	Blender, 3D software	Specifically tailored for Blender where the working color space is Linear Rec709.
`config_COMP_Lin709.ocio`	Nuke, Fusion, comp software	Tailored for compositing linear Rec709 renders (most commonly used for Blender pipelines).

Setting a system environment variable is the recommended way to load the OCIO configuration globally for all compatible CG tools.

Open your OS Environment Variables settings.
Add a new system variable:
- Variable Name: OCIO
- Variable Value: The absolute path to your chosen .ocio file (e.g. C:\color_management\AIO-OCIO\config_CG_ACEScg.ocio).
Restart your DCC application to inherit the variable.

Autodesk Maya: Navigate to Preferences > Color Management > check Use OCIO Configuration and point to the config path.
Foundry Nuke: In your project settings (S key), go to the Color tab, change color management to OCIO, and set the OCIO config to point to the file path.
SideFX Houdini: Set color settings via Edit > Color Settings > OCIO path.
