VRayOCIO is a texture that allows users to apply OpenColorIO (OCIO) color transformations to textures in 3ds Max to manage their look.

In the example shown, an aces_0.1.1.ocio file is used to define the output colors of the texture.

Image Modified

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

Slope rgb – Multipliers for the red/green/blue color components.

Offset rgb – Offset values for the red/green/blue color components.

Power rgb – Gamma values for the red/green/blue color components.

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

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

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

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

Direction – Specifies whether the forward or the inverse CDL transformation will be is applied.

Save cc – Allows the CDL parameters to be saved in a .cc file.

get values from file – When Use file is enabled, this button copies the parameters from the file into the texture parameters so that they can be adjusted if needed.

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

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

Cccid – Color correction id if present in the file.

Direction – Specifies whether forward or inverse color transformation should be applied. Not all file formats support inverse transformations.

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.
