OCIOFileTransform

This node applies a LUT transform using a specified file.

Connection Type

Connection Name

Function

Input

input

The place in the node graph where the LUT transform is applied.

 

Control (UI)

Default Value

Function

src

N/A

Specifies the src file path and name to use for the transform. This can be any file format that OpenColorIO supports: .3dl, .cc, .ccc, .csp, .cub, .cube, .lut (Houdini), .mga, .m3d, .spi1d, .spi3d, .spimtx, .vf

cccid

N/A

When src points to a .ccc file, specify the id to lookup. OpenColorIO::Contexts (envvars) are obeyed.

direction

forward

The direction of the transform, with forward being used to bake in a LUT transform, and inverse typically reversing out a previously-baked in LUT transform.

interpolation

linear

Specifies the interpolation method. This is ignored if the file used is not a LUT. The following interpolation methods are listed from fastest to most accurate:

• nearest

• linear

• tetrahedral

• best

context

Manually define keys and values for the OCIOFileTransform node.

key1; key2; key3; key4

N/A

Set a key that corresponds to the value of the same number in order to modify elements of the OCIO node, for example, setting a key called SHOT now tells the node that the corresponding value should be used for shots.

value1; value2; value3; value4

N/A

Set a value that corresponds to the key of the same number in order to modify elements of the OCIO node, for example, setting a value fora key called SHOT now tells the node that this value should be used in this context.
