Python script for generating neutral LUT tables of different sizes. It supports both Unreal Engine style LUT (top down) and the Unity style LUT (bottom up).
Based on a GitHub gist by Koki Ibukuro.
The script uses Python 2.7, OpenCV-Python and NumPy, which can be installed using pip (though perhaps not the recommended way, but it is easy).
pip install numpy
pip install opencv-pythonThe script can generate either a square layout or a long strip layout. Include --flipy for Unity style output.
python lut-generator.py --strip 32 --flipy output.png
python lut-generator.py --square 64 output.png
-sq --square use square format - accepted values 16, 64, 256
-st --strip use strip format - accepted values 16, 32, 64
-fy --flipy flip the image vertically
| Size | Unreal Engine | Unity |
