LUT

A LUT or lookup table is a special texture that is used to perform color grading. To create a LUT you usually use the neutral LUT and make the same color adjustments to it that you want to apply to your render results. LUTs can be used by Camera nodes.

Create

LUT textures can't be created like other files, they have to be imported with FxFile.Import and the FileType 224.

lutID = FxFile.Import(224, "c:\\MyFolder\\MyLUT.png", "");

Files

The default LUT is located at Programs\Foxel Studio\default.fxllut. Other imported LUTs are stored as shared files in Shared\Luts\ with the extension .fxllut.
