Factorio LUT tool

A tool which applies LUT colours to images.

Requires:

• Python 3.7+
• Pillow

Usage methods:

A. Process all images in the folder automatically

Simple to use method with little control over what the script does.

• Copy the LUT.py and _LUTs folder into your mod directory.
• Launch LUT.py directly, without any arguments.
• ALL found *.PNG images in this directory and subdirectories will be converted.
• Outputs can be found in _OUTPUT folder.

B. Process only selected images

Launch LUT.py with arguments, the most controllable way to use the script.

• -i specifies the input file
• -o specifies where to output
• -l specifies the LUT used (from _LUTs folder)
• -if -i is not used, all files in the current directory and all subdirectories (except _LUTs and _OUTPUT) will be searched
• -if -o is not used, the output file path will automatically be the same as the input, under the _OUTPUT folder
• -if -l is not used, lut-day.png is used

Example command:

• LUT.py -i nuclear_furnace.png -o _OUTPUT/nuclear_furnace.png -l lut-day.png

C. Drag&drop a file on LUT.py

Simple to use method for individual files.

• lut-day will be applied to the file.

You can find which images got which LUT applied in the vanilla_instructions directory.
