OCIO file transform
Last updated
OCIO file transform is a Colour effect.
What it does
Section titled “What it does”Applies a look-up table or an ASC CDL grade from a file, read the way an OCIO config
reads its own files. No config is needed. A cube is sampled tetrahedrally, where the
LUT effect samples trilinearly. A .ccc or .cdl file with
several grades applies the first.
