OCIOFileTransform node

pluginIcon

This documentation is for version 1.0 of OCIOFileTransform.

Description

Use OpenColorIO to apply a transform loaded from the given file.

This is usually a 1D or 3D LUT file, but can be other file-based transform, for example an ASC ColorCorrection XML file.

Note that the file’s transform is applied with no special input/output colorspace handling - so if the file expects log-encoded pixels, but you apply the node to a linear image, you will get incorrect results.

Supported formats:

.3dl (flame)

.3dl (lustre)

.ccc (ColorCorrectionCollection)

.cdl (ColorDecisionList)

.cc (ColorCorrection)

.csp (cinespace)

.lut (houdini)

.itx (iridas_itx)

.cube (iridas_cube)

.look (iridas_look)

.mga (pandora_mga)

.m3d (pandora_m3d)

.spi1d (spi1d)

.spi3d (spi3d)

.spimtx (spimtx)

.cub (truelight)

.vf (nukevf)

Reload / reload Button   Reloads specified files
CCC Id / cccId String   If the source file is an ASC CDL CCC (color correction collection), this specifies the id to lookup. OpenColorIO::Contexts (envvars) are obeyed.
Direction / direction Choice Forward Transform direction.
Interpolation / interpolation Choice Linear Interpolation method. For files that are not LUTs (mtx, etc) this is ignored.
Enable GPU Render / enableGPU Boolean On
Enable GPU-based OpenGL render.
If the checkbox is checked but is not enabled (i.e. it cannot be unchecked), GPU render can not be enabled or disabled from the plugin and is probably part of the host options.
If the checkbox is not checked and is not enabled (i.e. it cannot be checked), GPU render is not available on this host.
(Un)premult / premult Boolean Off Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
Invert Mask / maskInvert Boolean Off When checked, the effect is fully applied where the mask is 0.
Mix / mix Double 1 Mix factor between the original and the transformed image.
