When using the default OCIO v2 color management system, the input spaces that are available depend on the configuration file used by the scene. Only the spaces that are defined in the configuration can be used.
The author of the configuration can also limit the color spaces that are available to select for file textures, image planes, and so on by using the categories attribute of color spaces. If these are used, Maya includes any color spaces that have the category file-io.
The configuration files that are installed with Maya are named config.ocio and are available in subdirectories of resources/OCIO-config/ in the installation location. However, your project or studio may be using a different configuration with different spaces available.
The Maya-default configuration is used for new scenes. It includes the following input spaces:
| Input Space | Description |
|---|---|
| ACES2065-1 | Scene-linear values using the ACES2065-1 color space. |
| ACEScct | Quasi-logarithmic values using the ACEScct color space. |
| ACEScg | Scene-linear values using the ACEScg color space. |
| AdobeRGB | Images encoded in the Adobe RGB (1998) color space. |
| ARRI LogC (v3-EI800) / AlexaWideGamut | Images encoded using the Alexa Wide Gamut primaries and the EI 800 curve of Log C v3. |
| DCI-P3 D65 | Images encoded for DCI-P3 displays with an artistic white point of D65. |
| Gamma 2.2 / Rec. 709 | Images encoded with the Rec. 709/sRGB primaries and a gamma of 2.2. |
| Log film scan (ADX10) | Scanned film plates with the Academy Density Exchange encoding. |
| Raw | Non-color data, such as normal maps, depth maps, etc. |
| Rec. 1886 / Rec. 709 video | Video encoded using Rec. 709. |
| RED Log3G10 / REDWideGamutRGB | Images encoded in the REDWideGamutRGB color space using the RED Log3G10 curve. |
| scene-linear DCI-P3 D65 | Scene-linear values using the DCI-P3 primaries and an artistic white point of D65. |
| scene-linear Rec.2020 | Scene-linear values using the Rec. 2020 primaries for UHDTV. |
| scene-linear Rec.709-sRGB | Scene-linear values using the Rec. 709/sRGB primaries. |
| Sony SLog3 / SGamut3 | Digital camera footage in Sony SLog3 format. |
| sRGB | Images encoded with the sRGB primaries and gamma. |
The Maya-legacy configuration is used for scenes saved from Maya 2020 and previous versions. It includes the following input spaces:
| Input Space | Description | Primaries |
|---|---|---|
| ACES2065-1 | Scene-linear values using the ACES2065-1 color space. | Converted to the rendering primaries. |
| ACEScg | Scene-linear values using the ACEScg color space. | Converted to the rendering primaries. |
| Arri LogC | Digital camera footage in Arri Log C v3 format. | Converted to the rendering primaries, after applying the Academy input device transform (IDT). |
| camera Rec 709 | Images encoded with the primaries and gamma specified by Rec. 709 for HD video cameras. Note that almost no cameras actually use this encoding. However, this is very similar to a gamma between 1.8 and 2.2, so it might be useful if you have images encoded with a gamma of about 2.0 or to get a useful video-like contrast boost due to the difference between the input and view transforms. | Converted from the Rec. 709/sRGB primaries to the rendering primaries, after applying a curve on all three RGB channels. |
| gamma 1.8 Rec 709 | Images encoded with the Rec. 709/sRGB primaries and a gamma of 1.8. | Converted from the Rec. 709/sRGB primaries to the rendering primaries, after applying a single curve on all three RGB channels. |
| Gamma 2.2 / Rec. 709 | Images encoded with the Rec. 709/sRGB primaries and a gamma of 2.2. | Converted from the Rec. 709/sRGB primaries to the rendering primaries, after applying a single curve on all three RGB channels. |
| gamma 2.4 Rec 709 (video) | Images encoded with the Rec. 709/sRGB primaries and a gamma of 2.4. This applies the inverse of the gamma specified by ITU-R BT.1886 for HD video monitors. | Converted from the Rec. 709/sRGB primaries to the rendering primaries, after applying a single curve on all three RGB channels. |
| Log film scan (ADX) | Scanned film plates with the Academy Density Exchange encoding. | Converted to the rendering primaries, after applying the Academy input device transform (IDT). |
| Log-to-Lin (cineon) | Scanned film plates with Cineon-style log encoding. | No conversion of the primaries. A single curve is applied to all three RGB channels. |
| Log-to-Lin (jzp) | Scanned film plates with the Josh Pines, or "pivoted", log encoding. | No conversion of the primaries. A single curve is applied to all three RGB channels. |
| Raw | Non-color data, such as normal maps, depth maps, etc. | No conversion. |
| scene-linear DCI-P3 | Scene-linear values using the DCI-P3 primaries and the DCI white point. | Converted to the rendering primaries. |
| scene-linear Rec 2020 | Scene-linear values using the Rec. 2020 primaries for UHDTV. | Converted to the rendering primaries. |
| scene-linear Rec. 709-sRGB | Scene-linear values using the Rec. 709/sRGB primaries. | Converted to the rendering primaries. |
| Sony SLog2 | Digital camera footage in Sony SLog2 format. | Converted to the rendering primaries, after applying the Academy input device transform (IDT). |
| sRGB | Images encoded with the sRGB primaries and gamma. | Converted from the Rec. 709/sRGB primaries to the rendering primaries, after applying a single curve on all three RGB channels. |
