Basemap – The base texture to be corrected.

Config Src – Specifies the OCIO configuration.

Auto - Automatically finds the OCIO source by checking environment variable, file and the V-Ray internal configuration.
Environment – The OCIO environment variable is used.
File – Manually set the OCIO config file.
Internal – Uses the V-Ray configuration that includes srgb_linear, raw and acescg options only.

Config File – When the Config Src is set to File, specifies the path to the configuration file here.

Inout Type – Determines how the input and output color spaces are specified:

Colorspaces – The user specifies the input and output color spaces directly.
Roles – The user specifies the input and output color space depending on the task that they want to perform, as defined in the OCIO configuration.

Mode – Specifies what color transformations to be performed:

Color Space – The texture performs color space conversions.
CDL Transform – The texture performs an ASC CDL transformation. CDL stands for "Color Decision List", which is a color grading information exchange format developed by the ASC (American Society of Cinematographers).
File Transform – The texture performs a color transformation based on another file (i.e. .3dl, .lut, .cube etc).
Log Convert – The texture performs log2lin or lin2log conversion.
Display – The texture performs color space conversion for display.
Look – The texture performs a look transform. The OCIO configuration must define looks for this mode to work.

In – Specifies the input color space (the color space that the input texture is in).

Out – Specifies the output color space (for rendering, this would typically be a linear color space).

Look Input Colorspace – Specifies the color space of the base texture.

Look Looks – The name of the look, if the OCIO configuration defines looks.

Look Output Colorspace – Specifies the output color space.

Look Direction – Specifies whether to apply Forward or Inverse transformation.

Look Ignore errors – When enabled, attempts to perform color corrections even if there are errors.

These parameters are available when the Mode is set to CDL Transform.

Cdl Slope – Multiplier for the red/green/blue color components.

Cdl Offset – Offset value for the red/green/blue color components.

Cdl Power – Gamma value for the red/green/blue color components.

Cdl Saturation – The saturation value; 0.0 makes the image grayscale.

Cdl Direction – Specifies whether the Forward or the Inverse CDL transformation is applied.

Cdl Use File – When enabled, the CDL parameters are read from a .cc or a .ccc file, instead of specified directly.

Cdl File – Specifies a .cc or .ccc file to read.

Cdl Cccid – Color correction id, as specified in the color correction file.

Filetr File – Specifies a color transformation file (.3dl, .cube, .lut etc).

Filetr Cccid – Specifies a color correction id, if present in the file.

Filefr Direction – Specifies whether Forward or Inverse color transformation should be applied. Not all file formats support Inverse transformations.

Filetr Interpolation – If the file contains tabulated LUT data (i.e. .cube files), specifies how this data is interpolated.

Nearest – Nearest neighbor in all dimensions. This method is fast, but may introduce artifacts, especially in textures with smooth gradients.
Linear – Linear interpolation in all dimensions . This is a smooth method, but is slower than nearest.
Tetrahedral – Tetrahedral interpolation in all directions.
Best – Chooses the best interpolation type for the requested context. Currently the same as linear.

Logconvert Operation – Specifies whether to convert from linear to log space or vice versa.

These parameters are available when the Mode is set to Display.

Disp Input Colorspace – Specifies the color space of the base texture.

Disp Display Device – Specifies a viewing device from the devices listed in the OCIO configuration.

Disp View transform – Specifies the desired view transformation.
