OpenColorIO-Config-ACES 1.0.0 for ACES 1.3

The Working Group is pleased to announce the stable release of the new OpenColorIO Configuration(s) for ACES.

It is the culmination of almost two years and half of work and countless bi-weekly meetings. Those configs were designed to be lightweight and use the new features of OpenColorIO 2. We hope that they will be useful for the community and that they pave the way toward an increased adoption of OCIO 2.

We sincerely thank all the authors and contributors from the original OpenColorIO-Configs as it was always ingrained in all our discussions and decisions. We also thank all the contributors that gave feedback and participated into the Working Group meetings.

Config Naming Convention

Those new configs adopt an advanced naming convention so that they can be uniquely identified:

studio-config-v1.0.0_aces-v1.3_ocio-v2.1.ocio
|-----|-------------|---------|---------|---|
|Type | Colorspaces | ACES    | Profile |   | 

Where:

• Type : The type of the config, e.g. Reference, CG or Studio.
• Colorspaces : The colorspace definitions versions, semantically versioned.
• ACES : Supported aces-dev version.
• Profile : Supported OCIO profile, greater versions will enable more features, e.g. ACES 1.3 Reference Gamut Compression for 2.1 profile.

OpenColorIO-Config-ACES 0.2.0 for ACES 1.3

This release introduces the new ACES CG config, which is a beta OCIO config intended for use in CG lookdev, lighting, and rendering applications, and game engines. It implements a fully-featured ACES color pipeline without the many camera input transforms that make up the bulk of the OCIO v1 ACES configs, and which will be implemented in the upcoming VFX-focused ACES Studio config.

The CG config is completely self-contained (no external LUT files), providing a single file color pipeline with minimal clutter. It has robust support for the most common texture and working color spaces, and SDR and HDR output transforms used in high-end CG production environments. This config can be used as a starting point for studio CG feature pipelines, and is an excellent choice for bundled default OCIO configs in content creation applications.

Summary of the CG Config

• sRGB
• Rec. 1886 / Rec. 709

This highlight of this release is support of aces-dev 1.3 for the Reference Config.

Features

Reference Config

• aces-dev 1.3 support, note that the Gamut Compress LMT is not implemented yet.
• Display colorspaces family has been set to Display producing proper sorting in DCC applications, cf. #18.

OpenColorIO-Config-ACES 0.1.0 for ACES 1.3

This is the initial release of the OpenColorIO Configuration for the Academy Color Encoding System.

It features the first officially distributed version of the Reference Config.

This config is a strict and quasi-analytical implementation of aces-dev and is designed as a reference for software developers. It is not a replacement for the previous ACES configs nor the future ACES Studio Config.

It relies exclusively on OpenColorIO 2 features.
