Using OCIO for ACES
Color Management in Fusion
When using Fusion Studio or not using color management in DaVinci Resolve, you have the
option to use OpenColorIO nodes in Fusion to composite in an ACES color space.
OpenColorIO (OCIO) is an open-source color management framework for visual effects and
computer animation. OCIO is compatible with the Academy Color Encoding Specification
(ACES). Three OCIO nodes located in the Color category of the Effects Library allow you to use
OCIO color space transforms in Fusion.
 OCIO CDL Transform node allows you to create, save, load, and apply a Color Decision
List (CDL) grade.
 OCIO Color Space allows sophisticated color space conversions based on an OCIO
config file.
 OCIO File Transform allows you to load and apply a variety of LookUp Tables (LUTs).
Using OCIO for converting MediaIn or Loader nodes to linear gamma is based on the OCIO
Color Space node. Placing the OCIO Color Space node directly after a Loader (or MediaIn in
DaVinci Resolve) displays the OCIO Source and Output controls in the Inspector.
OCIO Color Space nodes can be used to work in an
ACES color managed environment.
Within the Inspector for OCIO Color Space node, Fusion includes default Source and Output
transforms for standard color spaces. However, to use the full OCIO standard, you’ll need to
download and install the OCIO config file. You can download the config file from the
OCIO website.

Clicking the Browse button in the Inspector will allow you to navigate to the downloaded config
file. From the download, locate the ACES 1.0.3 or later folder and select the file config.ocio.
Source and Output menus are populated based on
the config.ocio file that you download.
