The Maya ACES workflow (using Syncolor) is simpler to use with fewer transforms, for those users who do not need a full set of transforms.
More information about Color Management can be found here and here.
Set OCIO Config Path
This can be done in two ways:
- Next, you will need to add the path to the downloaded ACES configuration in Maya (most 3D graphics packages already contain a predefined configuration package), but in this case, we will use the downloaded version.
- Install the OCIO variable with the path to the config.ocio file. This can vary according to your ОS (you can install OCIO as the default color configuration for all apps). This can be in the Maya.env or in the user Preferences (similar to the OS variable but only for Maya). For example:
OCIO = C:\OCIO\aces_1.0.3\config.ocio
- Or you can set the path to the config.ocio file in the Maya Preferences for working with projects.
We will consider the second option:
- Start Maya and create a New Project. Open the Preferences window (Windows-> Settings/Preferences-> Preferences). Go to the Color Management settings.
Color Management Preferences
- Set the path to config.ocio at OCIO Config Path
- Enable Use OCIO Configuration
Set Transform Preferences
- Rendering Space ACES - ACEScg.
- Set the View Transform option based on the discussion above in section ACES Output Transform Choices. For example: "sRGB (ACES)".
Define Color Space Rules
Go to the Input Color Space Rules, and choose OCIO Standard Rule or Default. When using Default, you can change the color space by default to what you need, when opening all images in your scene. For example, choose ACES-ACEScg in Rule Conditions -> Add Image Color Space (for opening images), and save your Preferences and scene.
Alternatively, you can deselect 'Use OCIO Input Color Space Rules' so that you can add your own rules for various file formats.
Maya Color Management Preferences
For all other images, not converted to ACEScg, you will need to individually set-up the color space for the Image and File nodes.
