Select the format you want to use for your. This may cause the result to be unreadable in other packages. Turning this off allows superwhite values to be represented which are allowed in some packages, such as Nuke. In general this should match the input bit depth.Ĭlamp 3D LUT output values to the range of 0-1. ![]() For instance a 10-bit file has values between. The bit depth to scale output values to for. ![]() For example, a 10-bit file has values between. The bit depth to scale input values to for. Use this setting to get your output LUT values encoded the way your use of the LUT requires.ģD LUT (These controls are only visible when you’ve selected 3dl in the file type dropdown menu.) Some LUT formats are assumed to encode values as either logarithmic or linear. Some systems assume the LUT is designed to apply to logarithmic images, others linear. Together with OpenColorIO and the native Nuke Vectorfield node we feel all the Nuke color management issues for which the Truelight node was originally intended are now addressed.įor further information on Baselight for Nuke, please contact preLUT The Truelight node has been superseded by the free version of Baselight for Nuke which itself can import a BLG (Baselight Linked Grade) that can contain a Truelight strip, plus optionally a lot more in terms of creative grading intent. Note:FilmLight and Foundry have elected to no longer bundle Truelight as of Nuke 11. vf - Nuke's native LUT format used by the Vectorfield node (3D). cub - FilmLight Truelight LUT format (1D and 3D). csp - Rising Sun Research CineSpace LUT format (3D). cms - Light Illusion LightSpace CMS LUT format (1D and 3D). blut - Side Effects Houdini binary LUT format (3D). 3dl - Autodesk and ASSIMILATE Scratch LUT format (3D). The following file extensions are recognized: If this is set to auto (the default), Nuke guesses the format from the file name extension. The file format of the LUT file you want to generate. The path and file name of the LUT file you want to generate. Inputs and ControlsĪn arrangement of nodes that do the color correction you want your 3D LUT to do, preceded by a CMSTestPattern node. For more information on how to generate a LUT in log colorspace, please refer to Working with Color.įor more information, see CMSTestPattern and Vectorfield. Tip:For good visual fidelity when using 3D LUTs, it is recommended that a log colorspace is used for 3D LUT generation. 3D LUTs can adjust saturation and brightness together, and are very useful for emulating a particular known look, such as Cineon. This is represented by a 3D grid or cube. For each input value, there are three output values. In 3D LUTs, the output values of each primary color channel are calculated based on the input values from all three channels (red, green, and blue).They are useful for quickly creating an image for viewing purposes, using less processing power, but they cannot be used to adjust saturation independently of brightness. For each input value, there is one output value. 1D LUTs assume that the primary color channels (red, green, and blue) are independent, and the output for a particular primary color (for example, red) only depends on the input value of that channel (rather than the values of all three channels). ![]() You can use the GenerateLUT node to create both 1D and 3D LUTs: LUTs are generated according to the size of CMSTestPattern cube size. Generates lookup tables, or LUTs, from color management nodes downstream of a CMSTestPattern node. ![]()
