I am running Darktable 4.6.1 on Windows and there are 2 issues with the LUT module I have found. Firstly, it will not load a LUT from the Program Files directory. I’m thinking it is probably due to admin permission issues. Secondly, when I move the LUT to some other folder it loads but says “INVALID”. This is a HaldCLUT I use with RT quite regularly so I know it is a valid LUT.
Wondering if anyone else managed to work with HaldCLUTs in DT without issue?
Works just fine here. Downloaded HaldCLUT from the RawTherapee link, unzipped and installed in a specific folder, set up in dt the path to the folder in “processing” → “LUT 3D root folder” and now I can use these LUT within the LUT 3D module.
