Method
This Node applies a Colour Look Up Table to the Image.
Colour Look Up Tables (LUTs) are a method of transforming the colours of an image. They are used extensively in colour grading in post production. Notch supports the standard 3D LUT format of .cube, exported by the vast majority of colour grading packages.

Attributes
Name |
Description |
---|
Active |
Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance. |
Blend Amount |
Changes the opacity of the new effect over the original image. |
Blend Mode (RGB) |
Change how the generated effect blends with the parent image RGB. |
Blend Mode (Alpha) |
Change how the generated effect blends with the parent image alpha. |
Cube LUT |
The imported .cube resource. |
LUT Working Colour Space |
The colour space in which to apply the LUT. This should be matched to the space in which the LUT was authored.
- Gamma 2.2 – convert the input colours to gamma 2.2 space before applying the LUT.
- Linear – convert the input colours to linear space before applying the LUT.
