LUT management is short for Look Up Table management. This docker controls the HDR painting functionality of Krita.
This checkbox asks you to use Open Color IO(A colour management library, also reffered to as OCIO), instead of Krita's internal color management. This is required as Krita uses OCIO for it's HDR functionality.
This allows you to choose the engine.
This allows you to browse your files for a OCIO configuration.
|Some system locals don't allow you to read the configuration files. This is due to a bug in OCIO, and can be fixed in Linux by starting krita with LC_ALL=C krita from terminal|
