Apply Colour LUT
Apply a Colour Look Up Table (LUT) to an image.
Apply Colour LUT
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.
Parameters
These properties control the core behaviours of the node.
Parameter Details 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.
Apply To Solid Geometry Only Toggle whether the effect should only apply to solid geometry, or the whole of the scene.
Apply To Filled Pixel Only Only apply to pixels with some content on them. useful for virtual production contexts, where post-fx applied to the front plate shouldn’t apply over the backplate.
Toggle which of the RGBA channels are affected by the effect.
